Bad / low audio from this phone - HTC EVO 3D

Hey guys, does anyone have this issue? The audio from the loudspeaker is just crap, and also the position of it is away from the screen?? What sense does that make? I'm trying to watch a video, not broadcast the video's audio to everyone in my general area (except me).
Now that's a physical problem and can't be fixed. What I'm really mad / inraged about is the jack audio. Any type of headphones I plug into is extremely quite. Compared to my old phone (xperia play) I can't hear anything....is this normal? Does anyone else have any similar problems? I can't even wear these outside and listen to music, the wind and car noise is far louder. I'm forced to bring my old xperia play instead just to hear something (which btw, it's like twice as loud on this phone) and if that's going to be the case every day then it's time to sell this Evo 3D.
Another side note is that the range of the audio is also not very good, I can hear it struggle with high ranges as it makes "pops" in the audio...very disappointing..

My audio has always been fine, but maybe you could try using an EQ or something (might need to be rooted)

It's possible that my phone is faulty, but let me ask you this; what volume is your phone at when you think it's fine? I have to place mine at max to be "fine", not great, but fine. While the xperia play is at 50% being just fine.

I personally keep mine at 30% - 40%, it's a comfortable volume. Anything past 70% is a bit too loud. Do you think it may be your headphones..? Or it could possibly be a software issue like your ROM.

Originally I thought it was my rom, so I flashed another; same issue, so then I flashed the RUU...same issue. Tried different headphones, same issue, tried the same headphones on different devices...works completely fine at loud audio. Guess the phone is screwed. It already doesn't have any gsm radio connectivity.

Are you using the HTC headphones? Because after plugging in the original HTC headphones it came with, I found that these headphones are loud and working correctly. So it seems that any other 3rd party headphones will not duplicate the same result. That is unfortunately because I hate the htc ones, they don't cancel out background sound at all. They all have the exact same jack, 3 rings, same size, etc. But the HTC one is different. When plugging those headphones into my xperia it gives an error and says they aren't supported. So it's obvious that HTC put some type of technology into them that differs them from regular headphones.
Edit: Alright, so I tried yet another pair of headphones lying around and they work fine too. Is it possible that I tried the worlds only two headphones that don't work well with this phone? In any case, I'm no longer mad about the jack audio, it's obviously fine. But the loudspeaker is and always will be an issue, which sucks but oh well.

Nope, using third-party (JVC) headphones. Good to see you've got it sorted out though. Also I agree about the loudspeaker, it's a piece of crap. My old Evo 4G had a better one.

My phone is quite loud!
On mwakious Rom and it has tweaked audio settings.
It's gsm but maybe try the xloud mod available. Should improve audio volume

[Q] Static/background noise on audio

Hi All,
When I use headphones (tried 3 different pairs) whenever I listen to any audio output, whether from a game, mp3s, radio, system noises, there's always a lot of static and/or hiss. It's in the background and not too terrible but I'm thinking there's something wrong with the hardware in my Photon. I tried taking out the battery and it made no difference.
Anyone else have this issue? Should I return it? Any advice?
Thanks!
I use Moto bluetooth headset to listen and don't have any additional noise over what would normally be there (say, compared to what it sounded like on my EVO).
Do you get this background noise through the phone speaker as well or just the headset? Might be something with the audio plug on the phone.
If you have tried other headsets and the phone speaker is either doing it or not, wouldn't hurt to take it in to a Sprint store and have them check it out.
Thanks CCallahan. I exchanged it and the new one doesn't do that so I guess it was just a fluke.
I have the same thing going on, with headphones only. Guess it's just the luck of the draw
Sent from my MB855 using XDA App
I would exchange it. I guess it is the luck of the draw. My new photon has been less buggy overall - not just with this issue. The other one wasn't terrible but there were a lot more fcs and hard crashes. Could be just coincidence but with the audio jack issue too seems like there just might be bad ones out there.

[Q] Static noise through earphones

Hi all,
I have this static/buzzing noise whenever I play music. It just stays there in the background and it's completely noticable. I also get this sound, whenever I get a notification, like a sms, e-mail etc. also, if I turn the volume to 0 and I play a song, all I hear is that static/buzzing noise.
But, whenever I pause the music, the noise stays there for a few seconds and than it dissapears. But when I play music again, the static/buzzing noise comes back...
I have tried different roms, kernels, music players and different earphones.
None of the above seemed to solve my problem.
Could anyone help me?
Thanks!
Have you tried other headphones? Have you experienced this on other devices? I ask because it is normal to hear a little hiss/noise from audio devices when they're powered and no signal is coming through if the volume is up. Just some devices have more than others... If it's buzzing, though, that could be a bad ground in the connection. It could be the headphones or the headphone plug on the phone.
If another set of headphones doesn't do the trick, you may have something faulty on the Evo. That is if you already went back to full stock to test.

I tried many headphones, no static noise when it's in an iPod. Never experienced a static noise on my iPod.
so you tried other pairs of headphones in your evo? Not just compared ipod to evo right? The plug could be touching a little differently in the evo between headphones and might be completely different in an ipod. This is why some people experience tracks skipping randomly when there's an inline mic.
But if another set of headphones with the evo produces the same problem, it could be faulty hardware. might have to get it replaced if it's that big a deal to you.
Good luck, just hope I could be more help. It'd be easier to hear and get a clearer idea of what is happening exactly.

Discovery about headphone noise (humming)

I looked and didn't see anything about this, so forgive me if it's been posted already.
I noticed, like a lot of people, the annoying humming that this phone makes when you listen to music (for me most apparent when I have it hooked to my car stereo) but I was listening to music with a portable speaker, speaker connected to my LAPTOP (not the phone), and I moved the phone close to where the 3.5mm plugs into the laptop, and I heard the same buzzing sound. 0__0 ... So I think the humming is coming from some one of the wireless radios.. not sure which one, but after a few seconds, it wouldn't hum anymore, which means the radio must have shut off...
Again, forgive me if this is already known information, but if it isn't ... this may help some people, maybe the GPS radio causes the noise?? or Wifi??

yeah its the 4G LTE radio. it makes your speakers make weird crazy signal noises when it's too close, too, just like the old GSM flip phones did back in the day

Yep found that out on day one. Switch to wi-fi or turn off data and all will be well. If you're streaming in the car, I barely notice it with the music turned up. Droid Charge didn't have this problem, but it also didn't have an amplified headphone jack. I had to turn my car radio up way higher than my iPod with that phone, not the case with this one.

You've got to be kidding me... That is nuts, and that buzzing drives me absolutely CRAZY! I noticed something that with my Beats over ears, every time I touched the screen the buzzing would start, couple seconds it would go away. I put the phone into airplane mode and presto, all the buzzing was gone! Verizon HAS to do something about this, it makes the headphone jack virtual unusable!
HTC Is Aware Now
So after getting my second device from Verizon with the same issue I was finally transfered over to HTC. After an hour conversation and then some back and forth emails HTC is now aware! Very exciting as this issue has been bugging me for a while. They have now replicated the issue and are going to begin work on a fix!
Email From HTC said:
Thank you for the information. Unfortunately, it did not take me long to test the issue and replicate it with my personal device. I use in-ear ear buds and will be forwarding this to our corporate office in the morning so that we may complete some additional testing on the team and hopefully find a permanent resolution. I appreciate you bringing this to my attention.

Though not sure how exactly they could fix this without a hardware change. Rezound had same issue.

Anyone try a Ferrite Split Core? Not sure if it would help but if you have one sitting around it would be worth a try. Just wrap your audio cable through it a few times, worth a shot. Maybe two one at each end. See attached image.
I've run into this myself, however.....the humming does go away on it's own after a few seconds even when I'm downloading a large file over LTE....that tells me that while it still may be a hardware issue, they likely have filters in place that the software isn't triggering in a timely fashion. So it's possible it could be fixed in software.

Did you ever hear anything more on this? I listen using quite sensitive molded ear buds, and am considering returning the phone. What good is an expensive media device that sounds like a lumber mill?

If you're using expensive IEMs, why are you driving them with the built-in amp? You need to use an external amp and use a player like Neutron MP to line-out to it.

Thank you! I have considered picking up an external USB DAC. Can you confirm that the stock ROM will support it, and are there compatibility concerns with specific DACs? I'm not an audio engineer any more, so I can't justify spending much...

The E17 is a great USB DAC, if that's too expensive, the E7 is a good alternative. You can use an OTG cable and do USB audio, or line out using Neutron. :good:

I turn off sync when I listen to music and it does the trick. But I also keep sync turned off when I'm not on WiFi so its not really a big deal.

It's not the LTE radio causing it. LTE does not use TDMA (time division multiple access, as opposed to CDMA) as in traditional GSM. It uses a different form of signal transmission called OFDMA (orthogonal frequency division multiple access) which is continuous transmission like CDMA, which does not make speakers buzz. Most of the cause of this is the circuit being closely tuned with the flow of power in and out of the battery. If you plug in the phone to charge while using the headphone jack, it should be even louder and more apparent.
A quick fix for this is to put whatever you're using through a noise filter. This one is only $10 on amazon and is better for those listening through speakers rather than headphones. As for me, I don't really hear it much on my phone unless its plugged in, in which this little filter fixes the issue.

Really, then how come whenever I switch to 4g i get buzz, but while on 3g or WiFi it doesn't buzz. And on top of that HTC has said its the 4g antenna causing it.

Coincidence? I've never gotten any buzz, and I'm always on 4G.
Not happening here on stock. I use headset for about 3 hours a day. Best sound yet and i'm a picky listener with only high quality headsets. My Bose OE2 would have picked up any noise.
a little off topic... I havent tried to replicate this on my DNA yet but my iPhone 5 and everyone iPhone I've had since '07 (I've had them all) have this buzzing noise in the car when I have them playing through the aux jack AND charging simultaneously. when I unplug the charger, noise is gone...

[Q] Bluetooth to car stereo phone noise

Hi all. New here, so hopefully this will be concise enough.
T-mobile HTC Amaze 4g, no mods, all stock plus a few apps. Everything working fine on the phone. Purchased a Platronics BT headset, works OK; limited range, but passable. Just bought a Sony MEX-BT4100P car unit. Did the install myself (retired auto technician, so I know a little about doing it correctly). All working OK, BT pairs fine, functions all good (Phone book, redial, etc). Problem is a buzz noise during calls, only audible on the other end of the call, but it's pretty loud. Sound is similar to a slightly shorted mic cable. Voice is audible, just a loud background buzz. No noises with any other car stereo function. No noises with any other phone function.
Talked to car stereo vendor, they sent new unit and microphone. No change. Talked to HTC. They say that since the Plantroncs works fine, there's no problem with the phone.
I'm trying to find out if anyone else has experienced this specific issue and if so what had to happen to resolve it.
Any thoughts? I don't have another BT phone to try
Android 4.0.3, Sense 3.6. Don't know what other info might be helpful.
Thanks.

Hey Charlie,
I remember having a plantonics headset. They were awful for me and they broke eventually. Did you try another headset? I think the headphones you're using could be the source of the problem. Hopefully someone else experienced in BT and headsets can assist you.

The Plantronics headset is fine; it's the Sony car stereo BT function that's making the noise...
It's been a while since I've had the stock ROM on my phone, but try looking under the settings menu in dialer for 'noise suppression' and make sure it's ticked.
Does your head unit have a gain setting for the mic? I had a JVC unit that had one in the Bluetooth menu settings.
Actually, I just looked up your manual, you do have a mic gain.
It looks like you also have an echo canceller/noise canceller setting as well. See what playing with those do for you.
Failing those options, it sounds like you have interference in your mic. Try routing it away from any wires that carry current. You might try just holding it out in the open and making a test call.

Head unit - I've tried all settings on mic gain and noise cancellation with no changes at all to the noise, although voice quality changed as expected.
Microphone has been pulled out of the car, literally to the full extent of its cable, with no change. I've wrapped the mic and its cable in tin foil and jumpered that tin foil shield to chassis ground with no change.
It does indeed to me sound like microphone interference, but nothing I do, including a different mic, changes the noise. Head unit and mic have been changed out for new.
Does it happen even with the engine off?

This tells me it's not interference, at least not from the car's electrical system. Do you happen to live under high tension lines?
Ok, here's what we've got in an extremely simplified flowchart:
mic------>head unit------->bluetooth-------->phone-------->person called
Follow the path, eliminate as you go.
1. Unplug the mic completely. Make a test call, see if your caller hears the noise still. If not, it's either the mic (replaced already, but not unheard of to get multiple bad ones. Try a desktop computer microphone?) or poor shielding in the radio (not easy to fix, even harder to locate.) If it's still there....still might be shielding in the head unit. Unlikely though.
2. You've already messed around with the head unit's settings. Nothing to do here.
3. Bluetooth. My radio used a USB bluetooth adapter, yours is built in. Can't try a different BT.
4. Phone. You don't know someone with a phone with bluetooth? If pairing with a different device results in a clear call, it's the phone (you could try rooting/updating/replacing it. Maybe they just don't like each other?) If the noise is still there with a different phone, it's either the head unit (you got another bad one or they just don't make them very well) or it's outside your control. Maybe the tower itself. You could try driving quite some distance away, till you're on a different tower. See if it's clear then.
Beyond all this, I really don't know of anything else to try, apart from getting a different head unit.

I did try unplugging the mic and the noise goes away, but according to Sony and the vendor, if a mic isn't plugged in, the entire audio chain gets muted automatically, so it's not much of a test. I'm going to see if I can dig up another mic like a computer mic with a mute or on/off switch and see what that might do.
I'm in a rural area and not too many cell phones I can borrow here. Might be one I can find...
I'll try another tower too; that's something I have not tried. But this really sounds like audio input chain noise rather than post-processing noise. I was an audio engineer in a previous life and I am still leaning towards mic-related issues...
Thanks.

Update... Tried driving to another location, and voila! The noise disappeared. I'm now getting normal audio from the system. And what's really strange... back at the house the noise is gone as well...
Thanks to all for the suggestions and ideas! Glad it wasn't something more difficult to fix...

Audio qulity from headphone jack

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....

I've noticed it. Seems to be worse when charging.
Verizon remotely detected root, warranty voided.
Posted about it here.

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"?
