Question Low volume on USB C to AUX - Realme GT 2 Pro

Hi All
I listen to music in car a lot streaming from Spotify, and have been using a standard AUX connector on a stock radio in a Corolla 2011.
Before the Realme GT2 Pro, I have been using a Lumia 650 and the sound was amazing. Balanced, loud and not lacking in any area. My volume settings were Max on the lumia, and about 40 out of 60 (max) on car radio (and this was already very loud). Before Lumia, I used Galaxy S7 and while the sound quality was slightly worse than Lumia, the loudness was still OK.
I borrowed an OEM Samsung USB C to AUX connector and found out that the sound from GT2 Pro is too quiet. With GT2 Pro volume at Max and my car volume at Max (50) it was much quieter, I could hear noticable distortion, and the sound profile seemed flat. Almost as if there was no pre-amp in the GT2 Pro.
I have a suspicion this is not an isolated issue to Realme, but to all phones that pass audio through USB-C.
My question is:
What would be the best way to get same or better quality of audio as any phone with a pre-amp/integrated audio chip out of Realme?
I am considering:
- Do I need a different USB C to AUX adapter? The adapter tested was original Samsung USB-C to 3.5mm, not a knock-off.
- An aux-to-bluetooth kit, however bluetooth streaming is generally LoFI
- A USB powered DAC? Ideally one that can take bitstreaming audio from phone via USB C and pass into AUX lineout
- Replacing stock radio. I really do not wanna go this route as I feel it is redundant, because my cheap a** Lumia sounds superb on it, and Galaxy S7 was good too.
- Some kind of jerry-rigging offline Lumia to handle audio streamed from GT2 Pro. I have no clue how this would work
Any suggestions are most welcome!

It's due to a recent law that limits the sound level on phones and accessories.
I bought the apple 3.5mm usb c dongle and tried it on my car and same story it's very quiet, have to crank to the max.
The European version dongle have limited voltage compared to the US version and Android also has a limit on the volume but you can change if the phone is rooted.

Hmm.. I read that apple usb-c adapters don't play nice with android phones and are quiet by default.
I've tested a Samsung OEM adapter. As a band-aid solution, I am hotspoting wifi from Realme to Lumia.
EDIT: Here are the findings so far:
1. Tried installing Viper4Android with no avail. Driver not found loop. Maybe someone can figure out a method that works.
2. Confirmed the sound is much louder when Samsung adapter is used with a Galaxy S10+ as compared to Realme
3. Dolby Atmos EQ in Realme actually worsens the quality
4. The volume can be boosted with a shell command, but only with root and after the adapter is plugged, since it acts as external audio device. Tasker or other app can be set to run the command on headphone adapter plugged in
The command is:
su -c "tinymix -D 1 2 100"
Where the "100" is the gain
To display all adjustable variables:
su -c "tinymix -D 1 2 -a"
The default value for Samsung adapter is 83, where 84 is equal to 0dB gain. Maximum range setting is 108, which would be equivalent to +24dB gain.

BIG PROBLEM...terrible Noise USB Docking audio/charging out

Has anyone noticed terrible noise when using an S3 docking system or cable to output both Audio and Charging?
- extreme hiss and random noise, machine processor noise, crackle etc. (only if charger is plugged in as well)
- after 2 seconds of no sound, you can hear what resembles to be an AUDIO gate...that kicks in and mutes the noise until you trigger your next button sound.
- Even if you listen to a song, and think it doesn't happen while listening to a song...IT'S still there...fighting the song and causing degradation in Audio quality.
- not too mention, phone calls will NOT route through the USB jack, and music and navigation type stuff.
- if you unplug the charger, the sound cleans right up and sounds fine. It's the combination of having the audio and charging outputs all in one.
- ground loop isolators do not help
I have a background as an audio technician and some electronics skills and I did hours of testing and modding...unfortunately! All failed. I own an Ibolt car cradle (which I did most of my testing with), a KiDiGi desktop docking cradle, and I even hand made a cable that could trigger docking mode. All three of these scenarios FAILED with the NOISE factor.
I have resigned to thinking it is a hardware design bug with the S3. I have modified my Ibolt so that it sends out audio from an extra cable that plugs into the Headphone Jack...which as a bonus, as sends Dialer audio.
(I just realized that this is the i9300 thread, and I have a i747m but maybe this thread could help all the same)
I've had three S3's and used USB audio out to my car stereo via 3.5mm. None ever generated any additional noise.

Eddie...can you confirm these points:
1) You have a usb cable or dock that comes out the bottom of your S3, and it splits into USB for charging....and 3.5mm for audio? (NOT THE HEADPHONE OUT)
Is it a cable or dock and would you mind tell me the name of it?
2) What do you plug the audio into?
- stock car audio input
- front aux input on a car deck stereo system (stock/aftermarket)
- rear aux inputs to aftermarket stereo
- other?
3) with the steareo turned up fairly loud, but no music playing, do you hear any noise when you click buttons (assuming you have audio enabled for button clicks in Android settings) When pausing between loud music, do you hear any white noise, machine noise, hiss etc.?
4) What is your S3 model? (i9300?) and what OS version.

I don't remember any noise when clicking buttons?
But we're talking about AUX input which is analog, so when you turn the volume up with no music playing, you'll always hear some "soft" occasional clicks & hiss.

AT&T GS3 with various ICS ROM's. I don't use AUX anymore because my favorite ROM (AOKP) doesn't have audio out capability when docked.

Thanks for replying Eddie. I am so sick of this troubleshooting this crap sometimes. I am very happy with the S3. It is a giant leap forward from my HD2...in most ways...but not all. I am suspecting the USB audio out on my S3 has a defect.
Right now, in the car, I have resigned to using the USB for power and the Headphone jack for audio send to the AUX input of my Sony car stereo on a custom wired Ibolt docking cradle. I still get some PROCESSOR noise when pressing the buttons but it is about 5% of the intensity of using the stock wired Ibolt, or KiDiGi desktop dock...or my hand wired Ycable. Without the USB charging wired up, there is NO NOISE whatsoever with either method.
Digital Output
Reading many threads last night, I discovered that with some roms/kernels, it is also possible to output pure DIGITAL audio from the S3 USB port into a select number of little affordable boutique like amps which decode and amplify the audio and power spkrs and headphones.
My first S3 had some weird noise when using bluetooth. So I drove over to my local corporate AT&T store and let them know. They walked out to my car with a demo S3 and we tested it and it didn't have any noise at all. So they swapped out my phone for a new one and I've been happy ever since.
Maybe you could try that?
Regarding boutique amps... this guy in one of my threads was talking about that. I didn't understand half of what he said.

Yup that's it. There are a few examples on youtube. Interesting how it's this TRADE SECRET feature. I mean, I have not seen this advertised anywhere and the places on the net where I found examples....the guys talk about it as if it's this common well known feature. Apparently, next to having one of these setups, the Iphone4 has the the best rating for sound/volume/curve output...almost neck to neck with a dedicated DAC...I think they call it!
I bet if I spent another $100+ bucks for one of these amps, and ran it in my car through a power Inverter (12v to 110v inverter), that I could run the Digital signal out without the interference of my USB analogue out issue. But, I am past that now.
Thanks for your input Eddie!
DAC direct solved this problem for me with Siyah Kernel.
This also happens when you are charged with a car charger and using the line out.

Arkanius...are you saying...
1) You had the same terrible noise when charging in a car.... with usb audio analogue into aux input of car stereo?
2) and that you hooked up a DAC to resolve the car noise issue? If yes, would you mind sharing the DAC model with us and the cable used?
Although I may be digging up an old thread, it may be worth looking into (Currently majoring in Electrical Engineering and having completed two signal analysis classes).
themadproducer, were you able to get a spectrum output of the noise? If it just a set of static frequencies, a cascading array of notch filters may work out
EDIT: reading your mention of the USB charging, its quite possible that if the voltage converter is of cheap quality, the transistors involved in the voltage conversion from 12.0-14.0 Volts DC down to ~5.0 Volts DC may be giving off Radio Frequency noise, with the noise being picked by the audio cable due to physical proximity, akin to cross-talking in network cables ( a form of mutual inductance)

Phone as an external DAC for stereo?

Has anyone figured out if you can use the phone as an "external DAC", use the ESS DAC but in a "line-out" mode for connection to a stereo via analog cable to their stereo line inputs? I tried using it normally, and the DAC showed as enabled, but the quality was not as impressive as I had hoped (in comparison to my Marantz UD5007 when playing a standard red book CD via it's analog output to the same input on my stereo).
thanks!

What kind of cable did you plug in? LG set it up to limit the DAC based on the cable plugged in, I'm assuming they did this as most users probably use earbuds and the DAC at full power would probably damage most earbuds. And I've found in my car, plugging the aux cable in when its not plugged into anything enables the DAC at full power. I didn't discover this, some on headfi did.
I'm using a 3.5mm to stereo RCA cable into the line inputs on my stereo. The phone shows the HiFi DAC as being enabled but it is not in Hi Gain mode, and I get the HiFi volume adjustment levels when I change the volume. So basically the same as when I use it with my IER's, but not Hi Gain mode like when I plug in my Sennheiser HD580's. Which is fine, but I'm wondering if I can bypass the amp while still using the better DAC.
thanks!

Low volume for headphones solution

Some of you may agree but some may disagree. The audio output of the 3.5mm headphone jack is far to quiet.
A cheap and easy solution to this is I bought the USB-C to 3.5mm DAC from HTC. Join the HTC club and it was £5.95 with free next day delivery.
Much louder and very good quality. Can't find any specification on what BIT the DAC is and I don't have the tools to measure it but its far better than the build in 3.5mm jack.

I've got tinnitus in my right ear from constantly having a headphone in it for a number of years. I used to always listen on the loudest volume. With the xperia xz you can have active noise cancelling headphones, I can warmly recommend the nc31em in ear, I bought a pair for 15 bucks and it uses the processor of the phone so you don't have to carry a big dongle. Now I can listen at half volume and still hear everything better than I did before!
I received a Griffin iTrip Clip Bluetooth headphone adapter so I could be wire free from my phone and found this improved the loudness and remained good quality audio. You may get a bit of breakage occasionally if multitasking but for £14 from Amazon, it's a cracking piece of kit!
Fantastic solution
I have followed the steps of signing up for HTC Club, and ordering the adapter straight away. It really came next day with no extra charge for delivery. And oh boy, the sound is amazing! I am bit of geek when it comes to headphones, so i have a multiple different types. The difference between using the audio jack output of the phone and using the usb c adapter is NIGHT and DAY. Not only loudness is incomparable higher, the pure quality of the sound is improved in every way. I do not believe that there is DAC hidden in the adapter, as it is quite small and low priced. What makes difference in my opinion is the additional power phone can send to the headphones by using the USB C out. Difference is so big, that this workaround can be seen as hidden features to extent, as Sony has not said a thing about using your USB C out for audio. Now I truly understand why the removal of headphone jack make sense as even phones with not the best DAC and AMP can produce great sound thanks to power of USB C.
In case of Sony Xperia XZ however, it looks as DAC is of a top- notch quality(it officially supports Hi-Res codecs after all) but the AMP is criminally under-powered and so combined with Sony obeying EU regulations for safe listening volume converts to quality sound but on quiet side. But thanks to this adapter the DAC is no longer tied to volume level set by headphone jack.
Everyone who owns this phone must buy this, especially considering the low price of the adapter. You need hear it to believe it.

Two kinds of USBC to 3.5mm Adapters, beware.
Just so folks know, there are two types of USB-C 3.5mm adapters out there - Digital and Analog.
All decent phones should support the Digital adapters, since they are just USB Audio Class devices made small. You could also plug them into a PC. Because they contain the DAC and amplifier, they will be spendy.
However, the $2 Passive adapters have no DAC in them. They trigger a special mode of the phone that basically puts the USB-C jack into an analog 3.5mm mode and the rest is just plastic and metal. The DAC is in the phone. The phone has to specifically support this mode, and will likely indicate USB-C Analog Accessory Mode in their specifications. Xperia XZ Premium does NOT support this mode, and never will - it has to be built into the hardware.
Just sayin.

Because people are trying different USB Audio headphones. Sony is not in control of their quality or amplification since the DAC and amp are in the headphones. For those using different 3.5mm headsets, their quality varies greatly. Sony expects folks to buy theirs, preferably with their active noise canceling that they wrote software for. It works well but as stated, they are not very loud.

ok so I have an audio system in my car, and volume in headphones gets super low compared to CD (I know CD quality is the best you can get i think) but still its VERY very low compared to it, in aux on 13db I get same loudness as 7db in CD, which means I have to turn it on almost twice as much as a cd to hear same loudness, (why dont I simply turn my audio more than usual on a cd?) because I like listening to very loud music and I some times get to 23db on a cd and its very loud and on aux i must reach at least 40db to get close to being as loud but my audio system only supports up to 30db so I am getting aux loudness of 15-16db compared to CD.
will the usb 3.0 to AUX DAC help me get louder volume?

Mate 10 low volume through 3.5-mm port (with good 35ohm headphones)

Hey there!
I'm jumping off the Samsung Galaxy Note 4 ship, as it has suddenly died with all my data (thanks, samsung, for using slow and low quality
EMMC flash memory!)
just received my Mate 10 and the key issue (if i should dismiss weak vibro) is low headphone volume.
I have high-quality 35 ohm Denon headphones that deliver outstanding sound quality, and had no problems using them with samsung devices (Note 4, S3, tablets). I usually listened to the music on 60-70% volume and it was REALLY loud).
Now, with Mate 10, I had to max up the volume, but even at 100% it's not enough. Well, its sort of ok mostly, but not so enjoyable, and many tracks say "a bit more volume please".
Is there anything that can be done? I remember that custom kernels allow increasing volume, but that means rooting. Could anyone give an advice?
What is their sensitivity? If I use it with my Hifman HE400i the volume is also a bit low. They are 35ohm and have a sensitivity of 93dB. If they are really good headphones you wont be able to use them to their full potential plugged in to a phone anyways, so it will probably be better to pair them with an external DAC/amplifier. The usb-c port can output a bit of power, so you can probably use a decent usb DAC like the audioquest dragonfly for example. I use a hegel super DAC without any problems.

sensitivity 104dB/mW.
Well, the thing is that i used them with Note 4 and galaxy s3 (both are phones) with no problems - the sound was outstanding and volume very decent.
I did some more tests and found out that volume in videos that i see with VLC player is much higher (and more satisfactory). So the port is physically capable to deliver. Maybe should try a different media player?
You could try Foobar 2000. There is a setting called replay gain in the menu that will probably be able to boost the volume.

These are Bluetooth headset I think. I prefer wired ones
Samsung GH59-15198A, as provided with Note 10+ (and S20 series). I still use it with S23U. It can still be purchased online.
Galaxy Buds 2 (SM-R177NZKAXAC) working great.
I just use the google usb c headphone adapter
You need a USB-C to 3.5mm jack adapter that HAS A DAC. The reason why your Huawei headphones didn't work is because Huawei phones have the DAC built in.
I have both the S23ULTRA and an old Mate20Pro, plus a Huawei adapter (not working) and headphones (also not working).
Bought a 32 bit/192kHz DAC from AliExpress (overkill for my ears) and it sounds excellent.
I use a wired Sony MDR-EX650AP (stereo + mic) in-ear headphones with an iNassen USB-C to 3.5mm jack audio adapter, the latter bought initially for my e-book reader so I can still use wired headphones connected to its USB-C port.
I doubt this adapter has any DAC apart from what it is required for filtering noise and converting signal itself, however for months on this phone it's been working fine. Even at lowest levels sound is sufficiently loud, clear and the adapter is very thin and not bulky so feels like an extension to the 3.5mm cable. Of course, especially since the phone is frequently in my pockets, in moments the USB-C cable can "get disconnected" software-wise (physically it always stays connected) when moving or when the phone hits different parts of the belt or the pockets - S23U is massive, but this has nothing to do with the quality of both the adapter and the headphones. I bought the adapter on Amazon some years ago, although you may try something similar of another brand - just watch for highest possible bit/kHz ratio on specs and it should work straight away - the S23 Ultra is powerful enough to run (without DAC) any non-professional low-impedance headphones connected. Not certain about audio and mic though since the mic on the above Sony's stopped working for me after having this out in a rain last year. But it could, I see no reason why not.

You may doubt your usb c adapter has a DAC, but the S23U does NOT provide analogue music output to the USB C port. Without a DAC in the chain (in adapter, in headset, separate DAC) no audible music.
