Hey guys, are there different modes in the Quad Dac? The v20 had Normal, External,and High Impedance depending on what you plugged in. I'm not getting any regardless what I plug in, auxiliary, or normal headphones. Any ideas?
Yes, there are different modes. Long press on the Hi-Fi Quad Dac icon in your quick settings. This will take you to all of the different modes.
I just got my audio files sorted and onto a card and into my phone. I'll take my Senn's into work tomorrow and have a listen. Also recorded some FLAC files tonight that I need to listen to. I'll be able to tell you tomorrow at some point. Up to this point, I've just been using my B&O's and some Apple ear buds that we just have laying around work. Neither of which trigger high impedance mode.
I think I misunderstood the OP's question, sorry about that.
I haven't noticed any changing of modes by plugging in different earbuds either.
That's what I'm saying. With the v20 you plug in axillary cable and it changed to external. You were even able to fool it with an extension. My v30 doesn't have that option, but I've seen it in couple video reviews.

OP- do you mind posting a screenshot of what you are talking about. I had V20 and remember seeing high impedance mode when I plugged in my aux cable. Sound was 10x better when it was in that mode. So V30 doesn't have different modes anymore, just on and off? Thanks
Yeah, I'm not seeing anywhere where it shows normal vs high impedance modes but it is definitely switching. Had my B&O's in which are normal on my V20 then switched them out for my Sennheisers. The volume jumped and the sound improved. So there's switching going on even though it doesn't say it like it did on the V20.

I believe this shows what the OP is talking about. The V20 would show Normal, High Impedance, External, something along those lines. The V30 does not appear to.

Thanks! So I wonder if the DAC is simply always on in one mode when it is turned on?

It might be due to software version. When I first had the phone (shipped from Korea) mine showed this as well. After the first of two updates so far, it no longers shows normal/high impedance mode.

I don't even know how to tell if the mode has changed. I plugged in an AUX cord and I think the only thing visually that changes is the settings screen says that the volume or something has been automatically adjusted if I use earbuds. No matter what, volume is limited to 75 it seems and is just shy of being loud enough for me while mowing and such

It seems not all v30s are having the same software. Maybe new software changes the mode automatically but doesn't show, why would it. It seems to switch depending on what you plug in, I can tell in the sound quality. It's just the peace of mind of it showing you to know it's actually working I guess.

I hear ya. With the V20 there was either normal HIFI DAC mode and Aux or high impedance mode and TBH the normal mode just wasn't loud enough. That's where I'm coming from, if we see the mode then we know that it's on its best,loudest setting.
Idc if it shows it, as long as it's working. I was worried it wasn't and I was missing something. After all this was one of the main reasons I got this phone, the audio.

Hello all!
This could be the place for people to detail what outboard DAC's they're using with their GSIII. All of you audio centric people can use it as a source when shopping for a USB DAC.
Post some details about your phone, and what you worked with! Also, post what hasn't worked for you and maybe more knowledgeable members can help you out.
I looked for a thread on this and couldn't find anything so far. Hopefully this one will be helpful.
Here is a list so far of DAC's that are reported to work with the GSIII. Note that some of these also have amplifiers integrated in them.
-Emmeline "The Predator" (predator of wallets!)
-Fiio E7
-Headstage USB DAC cable
-HRT MusicStreamer II
-iBasso D12
-ODAC (Objective DAC by NwAvGuy and Yoyodyne Consulting)
-Topping D1 MKII
-Topping TP30
Here are some DAC's that people have reported DON'T work with the GSIII
-Fiio E17
-M-Audio Transit
Any others or corrections, please fill me in.
Anybody tried using one yet?
Are you talking about this?
http://www.slate.com/articles/arts/music_box/2010/12/dulcet_downloads.html
If so, nope. I don't think I'll ever have the need for one as I'm fine with what I use currently.
I'm not enough of an audiophile for it to matter.
Fiio E7 has been. I believe DACs based on TI USB controllers are more compatible at this stage.

Also I am guessing that you meant to write "Headstage USB DAC" it looks like it was just reviewed by Headfonia. No biggie.
Thanks for starting this thread....I would love to get better audio output from my GS3 into my car stereo system.
One quick question....Is there any way to have one of these USB DAC devices hooked up and be able to charge the GS3 at the same time?
I would love to be able to put my GS3 in a dock, hook one cable up to the microUSB, and have it be able to go to the USB DAC, charge the phone, and go into car mode. The car mode could possibly be achieved via NFC tags.
I appreciate any input on this.

No problem. I figured there must be some other curious people like me out there!
Maybe another person who has tried this can chime in, but it seems like you could do it. Possibly if you used a USB hub you could accomplish what you're trying to? Try and dig up a pin out of the GS3's usb port. It also may be possible for you to take an MHL or USB adapter and separate the pins used for charging from the pins used for audio out. Then you could potentially splice the wires to two separate plugs, one used for charging and the other for the USB data.
If that doesn't work, you could try and do the palm touchstone charging mod to your phone so that you keep charging and audio out totally separate. That's pretty involved just for a car dock but hey, I'm not one to know your DIY ability!
For me personally, car audio doesn't seem like the environment to benefit from a separate DAC. With road noise and all, would there be that much to gain quality wise? Haha, I'm probably just of that mind set because my car is pretty loud. Good luck with your project dude.

I updated the OP with a few more DAC's that have been reported to work. Let me know if you've had any experiences with these or others.
Bought Fiio e7 on Amazon and its en route. Should be here tomorrow. S3's DAC is too noisy and e7 will definitely come on handy.
Btw, those who already have one, will e7 use phone's power if it runs out of own battery power? Leaving on a trip soon and need to know if I should buy one of those 12,000 mAh battery packs just in case.

I don't know if you can use the S3's power to charge your E7 but I can tell you that the E7 has CRAZY long battery life. As long as you remember to turn it off. I'm really not sure you'll need it.

Ok, got my e7 and my gawd this thing is amazing. It can go so loud that it would probably blow my ears and headphones before I even get to 50%. Also, on the other side of the spectrum, it can play so quiet that ambient noise is louder than my music, lol. My goal was clarity at extra quiet volume and yes, e7 delivered what I was hoping for 100%. Set e7's volume to 1/60, phone's volume to 1/15, lower PlayerPro's volume even lower and wow the sound is still crystal clear. Of course there is still some of that natural white noise you usually get from electronic devices, which is almost nonexistent compared to other DAC's I've tried, but that can be easily fixed for the peace of mind by setting volume to 30/60 and then using a pair of resistors to lower the overall volume back to 1/60.
Oh and also, looks like the e7 WILL charge from the phone if you want to. Plugged it into the phone, made sure the "usb chg" is on, and I do see the battery icon on the e7 scrolling indicating that it's charging. Not that I'd need that after fully charging e7 before using but still, it's nice to see such flexibility
TL;DR: Mind, blown. The best $71 I've ever spent.
I was under the impression that the E7 had issues with the GS3. Now I'm intrigued.

Just wanted to know if anyone else noticed faint buzzing/scratching/hissing noises coming out of their headphone jack...
(and yes I have tested several headphones/earbuds and tested with my MDRv6's all with the same results. Its definitely the phone not the headphones)
When I insert my headphones there is a quick beeping sound that plays for a second or so then goes quiet.
When music is playing, especially soft music (a particular song was Instant Crush; Daft Punk) there is a hiss in the background, specifically when certain tones play.
It was terribly noticeable right at the beginning of a few songs, especially the one I listed above.
I also have button sound effects enabled. So When I press one of the soft UI buttons it makes a tick noise. However for about 5 seconds after the tick there is a long hiss then silence until I press another button.
The volume of the hissing/scratching noises is directly related to the actual volume of the device and the note playing.
Im on stock build 11c w/root, and I havent found a lot of info about this problem.
Just wondering if anyone has noticed this, or if this is a known issue?
If your phone is warranteed, I would bring it in
The G3 boasts an AMPLIFIED 1 watt sound speaker, which means there is a powered sound processor.. Unless the jack needs to be cleaned, I would lean toward thinking there is a defect in your phones jack, or sound assembly. I think its more than likely a defective jack, especially if there are no sounds like you are describing when headphones are not in use
Yeah the phone is brand new. I think I'm going to RMA....

Just got my G3 a week ago and didnt use headphones until I read your post, I tested many different songs with different players, stock player, google player, Iheart radio, pandora, etc, headphone sound is crystal clear on mine, I dont get any beeps either like you described, I did notice you need to make sure the jack is pushed in good and tight, I put it in and thought it was all the way in and sound was crappy, pushed a bit harder and it clicked in good and sound was great, do you have a case that may be preventing the jack from being pushed in all the way, I had a phone in the past that this happened to me with, had to cut away some rubber on the jack to make it fit snug, if none of those are the issue, I would look into a warranty claim. I am using the beats audio earbuds that came with my HTC M7 I had before this phone.

That could be the issue. I know on the 2012 Nexus 7, it's really bad. It's supposedly due to the microUSB port and the headphone jack sharing the same circuit, or some engineering thing like.
Wonder if it's the same or if they didn't shield the headphone jack very well and it's picking up interference from the microUSB port when charging?
I didn't want to leave this up in the air so I figured I would post an update.
I replaced my G3 through Verizon for a brand new unit. My first phone was of an earlier batch (came with the 10b update) the second one was of a later batch and had 11b pre-installed.
Both phones had the same issue. There is a hissing noise/distortion that comes from the headphone jack. Even when not playing music.
I noticed it on other phones too but not anywhere nearly as much. I understand that any audio source is going to have a little background interference but the G3 definitely has a more significant issue than others.
However it seems to be entirely dependant on what headphones you are using.
1st. I tested first with my Sony MDR-v6's which the problem is most noticeable on. Extreme hissing/background noise.
2nd. Then I used a pair of Audio Techina ATH-PRO500's and the problem was almost unnoticeable.
3rd. I also tried my Steel Series Siberia v2's and the problem was again almost completely gone.
4th. I also used my receiver at home. JVC 5.1 channel receiver with RCA speakers and a Kenwood sub, didn't notice the issue at all. However there where some occasional strange popping noises when no music was playing I didn't get on my GS3 or other MP3 player.
5th. Finally I tried the ear buds that came with my Galaxy S3 and the distortion was again totally noticeable with and without music playing.
This is most definitely an issue that totally depends on what headphones you are using not sure if it has to do with sensitivity or impedance (this is what most people think) however it is most definitely an issue. I saw a few threads saying that audio issues were a problem in Android 4.4.2 however LG/Verizon have yet to release a stock base on anything but.
I suppose I could flash AOSP 4.4.4 and see if the problem persists but I don't know if that would even be worth it.
2 phones and 4 headsets later this is starting to seem like either a software or a design issue.
However I have nothing but good to say about every other bit of this phone. Really besides the audio jack top notch all around.

I might have found a workaround for this
I have tested 3 LG D855 and all of them have noise/static/high-freq leak from the processor out to the headphones. It might be a faulty design for the headphones amplification stage for headphones (when the headphones logo appears on the status bar). However, when using line level output (the jack appears on the status bar) the problem does not reproduce.
Therefore the workaround I've found is to trick the phone into line level output mode and then plug the headphones. To do this you need to plug in a 3.5mm jack extensor or a 2-to-1 3.5mm Y-adapter with no load, that's it, with nothing connected to it. At that moment, the phone will activate the line level output mode. Only after that you will connect the headphones, and you'll see there are no artifacts on the audio.
That being said, I'm not sure this will work with all kind of headphones as I have only tried with mines that are low-impedance ones, but on those it works perfectly. To be checked if the level of the signal in line mode is enough to drive other headphones.
In any case, it is a shame this happens with a high-end and expensive smartphone. I was hopping this will be fixed in a newer hardware revision but I got two replacements of mine and no luck. I have read somewhere this might be a flaw in Snapdragon 801, as it integrates completely the signal routings but isolates badly highfreq noise from processor stages, etc. etc. but I do not remember where I did read it unfortunately.
I hope this helps!

Ive been having the same issue. I have a pair of Shure SE846 which are about 8ohms. I experience the poor audio, especially the noise in the left channel. I find that placing a call and then listening to music removes the left channel static but the sound is still kinda bad. Ill try your suggestion tonight and post back. Just wanted to let you know your not alone.
I despise my G3 because of this. Im looking to get a new phone unless I can fix this.
Nope, my sound is perfect on my high-end Sony over the ear phones. Crystal clear on pure stock G3 .
I haven't noticed any artifact issues on my phone when using headphones, however when I plug it into my vehicle and also plug in the charger that causes everything to go nuts. The USB interference causes a crazy amount of excess noise. I haven't ever actually tried listening to headphones while charging, so in the car is the only time I've ever noticed it. The same issue occurs when I plug in my Galaxy Tab Pro into the aux jack and charge it at the same time, so this is definitely not unique to the G3. I wish all phones had as good an amplifier as my HTC DNA does, I still use that thing for music because the sound is so good.

I'm having a different audio problem.
With headphones plugged in and listening to music using any player, the right side sound emits distortion/hissing noise at a certain frequencies. When I tested it with plugging a 3.5mm to 3.5mm to an external amp (JDS labs c5) the distortion/hissing noise is completely gone. So it's definitely not a faulty jack
The hissing is evident at the beginning of (first few seconds) Tina Area's Still Running and You set fire to my heart .
I'm testing it with sensitive iem (Westone Um3x).
So does this mean there is a problem with the internal amp of the g3 or more to do with the os bug that can be solved with a custom kernel or update.
Is this a common issue found on all g3s?

Hi! This worked perfectly for me but for me instead of tricking the phone into line level output mode, I detaching one side of my headphones before plugging it into the headphone jack then reattached it afterwards. I'm using pair of sensitive iems (Westone um3x rc)
Everything is quit with no distortion, just how it should be!
One thing, is there an option within android or an app that can permanently enable line level mode ever time headphones are plugged in without having to trick it.
If so, I won't have to sent my phone for repair!
Also are there any disadvantages for using line level with headphones?

Using line out shouldn't make any difference on audio quality. It only disables the remote (buttons and microphone).
Would also really like a way to force the line-out mode. Btw, does this affect all G3s? Cause right now I'm not sure if it's worth the hassle of replacing it.

I know but some how using line out causes the hissing from the right side to go away completely. Strange huh
Are you also having this problem?
I also don't want to return mine if it exists in all g3s and there's a easier work around.
Yea same thing. I have artifacts in the left channel except when I manage to force the phone to recognize the headphones as line-out. I did this with the adapter to test it and it's impractical if not impossible to use the same adapter all the time.
I'm gonna try doing this right this moment to see if it works: http://forum.xda-developers.com/lg-g3/help/hissing-noise-left-ear-playing-music-t2804065/page17

I don't use earphones with a volume remote or microphone so that's not a problem.
It could be more to do with the increase in output impedance but I might be wrong cos the volume level is identical to headphone out.
I'm also getting a lot of static background noise but it disappears after making and hanging up a call as mentioned in a thread.
But yeah a permanent fix by forcing it into line out or doing some changes in kernel would be much more convenient

Great news! I just tried the fix from that thread and it worked. Here's the post: http://forum.xda-developers.com/showpost.php?p=59601465&postcount=150
I'm using stock rom which had 3 mixer xml files and I edited 2 of them, mixer_paths.xml and mixer_paths_qcwcn.xml. Also, instead of changing the value to 0, I deleted the entire line as it was suggested later in the thread.
The artifacts/noise in the left channel are gone!

But mine is stock on stock Lollipop via official update and with the hiss coming from the right side.
Please excuses my ignorance but I know nothing about accessing and editing a ROM.
How do I get into the rom and into the file called system/etc"?
I'm using the tmobile v20 and noticed this morning that my DAC wasn't impacting the sound quality of Google Play Music at ALL. I have been using a v10 for the past year and I could tell that the DAC wasn't working, or it was broken, because my non-DAC listening on the v20 paled in comparison to the v10 with DAC on.
I went ahead and installed the DAC Fix for V10 and it seems to have fixed my issue. In case any of you aren't noticing the DAC working on streaming apps, try this. So far I've had no issues.

Thanks to: http://forum.xda-developers.com/member.php?u=4723056
Funny, listening to Google Play Music with my leftover Note 7 earbuds I hear a distinct difference when I toggle the HI-FI on and off. I tried installing the V10 fix app and can hear no difference enabling or disabling it. I did see that the settings for Hi-Fi say "The sound has been automatically adjusted to the connected audio device". Could the type of headphones/earbuds determine if it engages?
T-Mobile edition of the V20.
I also hear a big difference on my T-Mobile unit. I'm using a set of Skullcandy earphones, and toggling off/on is immediately noticeable.
I ended up testing some more...I turned off the DAC fix, yet the toggle still worked. So I uninstalled the DAC fix completely and the toggle STILL works. I guess my unit was stuck in the "off" position for some reason, but it's working fine now. Weird. Sounds so much better with the DAC on.
The DAC fix makes no difference on my V10. Once the dolby atmos is turned on and Viper, the sound quality is superior. My V20 is arriving today and I'm sure with my 1More earphones and that 32bit DAC my ears will cry for mercy.
I wasn't able to replicate your problem, but I must say... This audio quality is far superior than any other phone I've ever used, finally something deserving to be used with Denon Urban Raver's.
Soooo is the DAC fix only for streaming apps such as Google play?
This is my main source of music...
Im comparing the headphone DAC on the s7 and the v20 and they almost sound the same, Im activating and turning off the Hi FI on the v20. Im using an audio technika m50x. Should i donwload the app to fix the dac? im using a video from youtube to do the testing. going to use google music songs that i have download to see if there is a difference.

Other people's DAC worked fine for streaming apps without the fix. Mine WASN'T working, but now it is. I can't say why. But I'm like you. I use GPM for my daily music.

so mine is not working. is very close to the one on the s7 edge. Should i restore it? I also download the v10 dacfix but still the same. where is the better place to test it out. App wise?

It is quite noticeable on every music app I've used. The best way I would say is just listen to some music you like. I wouldn't know how to fix it, mine works perfectly. Try a factory reset?
Edit: I just moved from the S7 edge, and the difference is quite clear. I even think it's much better without the hi-fi turned on, but with it on it's significantly better too.

Sennheiser Momentum In-ear, SteelSeries Siberia Elite Prism headset, and both Samsung and apple ear buds that come with phones. There isn't a pair I can't tell the difference on.

I figured out a very easy way to tell. If your phone doesn't mute music for 1/2 a second when you turn it on, it isn't turning on. It should have a 1/2 second mute when enabling or disabling.
It does. So i imagine is better in the clarity or something. Because it doesnt sound louder than the s7.

how you are connecting them? first the cable to the phone and then to the headphones? or just plugging them
This dac fix did nothing for quality for me listening through my Bose QC15's couldn't tell a difference

So mine is confirmed working with google play.
plugged my vmoda crossfade LP2 wire into th3 phone , then into to headphones.
Press the DAC button and it is a slight bump in bass and volume. too bassy imo

Hello guys
I have ordered impedance adapter from ebay the one @ChazzMatt have mentioned at many posts
Before using that i wanted to ask that will it work fine with custom mixer path tavils file that is included in anxiousv30 which provides dual speaker and volume boost
or will i have to restore the original mixer path tavil stock file
also can i use impedance adapter with aux cables in car or not ? i mean its safe or not ?

Really don't need High Impedance.
Also don't use the adapter with AUX cables. I'm honestly trying to figure out why anybody would do that in the first place.
Edit, when plugging in the AUX cables, the device will go into AUX mode.
Sent from my LG-H932 using XDA Labs
The V30 in aux mode outputs the same level at max volume as my desktop Teac UD-301 DAC. You do not need more.
The whole boosting to high impedance mode is foolishness.
There are some headphones that need the 2 Vrms power of HIM vs the 1 Vrms of Aux mode. Planar magnetics in particular require a lot juice.
Playing at a lower volume level in HIM as opposed to at max volume in Normal or Aux mode may also slightly affect SnR, although we haven't been able to measure that objectively.
But I agree that going through hoops to force HIM with high sensitivity IEMs, only to turn volume way down is, well... :cyclops:
There is a persistent myth, going back to the V10, that HIM is needed to (fully) activate the ESS DAC, and that's what drives it.

I figured out why not to long ago.
LG is marketing high impedance as pure HiFi without mentioning the type of headgear that is giving high impedance. It's just marketing gimmick. Sure, full sized cans will give better sound while also going over 50 ohms. It would have been awesome if LG actually explained what they meant by having a better experience on high impedance.

Yes. I wasn't so much responding to that. I was merely pointing out that, while most of the HIM chasing is indeed unnecessary, there are a few cases where the extra power is needed, and where HIM is not triggered automatically.

Oh I agree man!
I also did a test on my 30 ohms IEM. Used an adapter to trigger high impedance. Talk about degrading audio quality.
All the people chasing high impedance is from misinformation. However as you always point out, some gear needs it though.

I used it with high quality 35ohm earbuds, but then later after rooting, I used Anxious V30 module to get forced HIM. So, I no longer need to use impedance adapter to force HIM.
This quad DAC will try to give you the best sound, depending on what you have connected to it. So, that's why some say you don't need the impedance adapters.
But the impedance adapters are just to do what the Anxious V30 module does (force HIM or the equivalent) or whiskeyomega's audio mods. If people don't want to do that, they don't have to.

Noooooooo
The distortion is horrendous! Mostly I guess due to the BA. You don't want Anxious mod either. You can possibly kill the IEM's. I would HIGHLY recommend not using a mod. You don't need forced HIM with the KZ.

Obviously you have a choice of whatever color you want. This particular color is out of an aesthetic choice. The cable is for audio. I also noticed I set the volume down lower with the cable. You do get a bit of volume boost . If you find the volume not loud enough, it's because of stock cable.
This really does help the KZ and CCA sound better. I've tried every genre of sound. 3+ hours going between songs and cables and both IEM'S. So it's not placebo.
I can always host high rez files that I used. Just pm me if you want some good examples.

ROOT Your LG V30!
https://forum.xda-developers.com/lg-v30/how-to/root-v30-t3927154
The Root Sticky specifically talks about DTS. . Bottom of post #1.
I use my phone with 16Ω, 32Ω and 60Ω IEMs/Headphones and I don't care about impedance mode. Sound quality is the same whatever mode you're in, it just gives more power/volume that's it.
If you feel that your headphones are underpowered even at max volume, that's when you should think about these hacks. In most cases it's useless and not recommended.
Hello, I was reading something that the V30 only uses the ES9218P DAC Chip when you insert a super high quality ear phone, can some one comment as to whether this is true? And if so, is there a mod or something to force it to use the chip at all times?

If you're on stock firmware the quad DAC is used all the time. However, how many of the quad (four) DAC channels are activated depends on the impedance of your headphones. Usually about 50 ohms for all four.
There are mods (requires root) to force High Impedance Mode (HIM) no matter what headset you're using. That's not always best if you're using low quality headset/earbuds.
I use a version of forced HIM -- using Anxious V30 mod, but she toned it down in later versions of the mod to only half the volume for earbuds with less than 50 ohms which didn't naturally activate "normal" HIM. She called it faux HIM or other names because some audiophiles argued with her terminology.
They'll probably argue with mine also -- but I'm explaining it so it's easily understood.

I will post a link that has a possible work around. I use it, but not sure that it is needed to enhance your low impedance phones. You can try it and see, I guess. It will be in the first post of the link as a "spoiler".
I also have downloaded an app that let's you know if it is in normal, external DAC (the work around), or HIM mode. The app is, "hi-fi status LG".
https://www.head-fi.org/threads/music-apps-tips-and-tricks-for-the-lg-v30.868978/
Use it or not. It may help or not. I do use the work around with my low impedance head phones.
The impedence modes only bump up the amplification to accommodate power hungry earphones.
There is no impact on sound quality. You should not worry about it, just plug in your erphones and enjoy.
