Naugat and USB DAC sound distortion - Nexus 7 (2013) Q&A

Hi
I got Nexus 7 installed in my car. Only device connected to it is Fiio E10k.
RR, and pure Nexus, both clean, running either on stock (whatever came with it) kernel or Glitch or ElementalX have same problem. No matter which player I use (YouTube too). I also run it on headphones from power bank to make sure it's not power supply related.
Sounds like random distortion, easy to hear especially during quiet parts of tracks (as long as some music is playing).
I assumed it's naugat related, as Android 6 doesn't have that problem (either stock with timurs or cm13 with ElementalX).
Any idea how to solve / troubleshoot problem like that?

I tried USB audio player pro with Los, and I don't hear distortion so far.
It made me think it's driver related. Maybe it's forcing different bitrate or something.

Distorted bass (headphone jack)

I am having a problem with the headphone output. When listening to anything bass heavy... such as house music, the bass is distorted. Its sounds almost as if the headphones I am using are blown. I know this is not the issue because I have tested several different pairs, all with the same result. I even experience this when I have the phone hooked up to my car stereo. Volume isn't an issue and everything else seems to sound fine... its just that bass notes and kick drums sound horrible.
I'm coming from a Vibrant which was a powerhouse with voodoo sound enabled.
I understand that the Yamaha dac in the SGSII is nowhere near as good as the Wolfson used in the SGS... but it shouldn't sound this bad?!?!
I have tried just about every audio/dsp app available to no avail.
Does anyone else have this issue?
Also... not sure if it matters but I am running Juggernaut v3.7
Any help would be greatly appreciated.
hmm I was going to suggest you get power amp and just turn down the overall level in the eq. that might help in troubleshooting where in the signal chain the distortion is coming from. If it remains distorted at low level i would assume it wsa a hardware problem.
Ive certainly not any problems with distortion as long as i keep good gain structure in my eq.
I have tried power amp. I also tried lowering all the levels down. Nothing works
I forgot to mention that the problem exists even at the lowest volume settings... quite fustrating
I really hope it isn't faulty hardware... not sure ill be able to get a replacement
Completely different hardware but I had this issue on my HD2 after either making the lower frequency settings too high with other DSP or equalizers or when I used root level volume boosters like Volume Hack+
Are you using a stock (non-flashed non-rooted) build? If not, you can try a nand backup and flash a fresh install of your ROM. Not installing anything and go back to the same songs to see if they distort.
The SGS2 can push a good amount of low frequency granted you have earphones/equipment that can pick up low frequency output. I use it in my cars and with my Sennheiser headphones with no real issues and great output. Even with max volume, no distortion.
The HD2 was capable of only so much before it distorted but I haven't been able to replicate the issue with my SGS2. But then again, I haven't installed DSP or any other 3rd party volume/equalizer apps.
Im running juggernaut 3.7 w/ bullet kernel. To be honest I didnt check what it sounded like prior to rooting and flashing the custom rom. I only installed the dsp apps to fix the problem.
A new release just came out so I will take your advice, wipe and start with a fresh install.
Hope it fixes the problem.... its really driving me nuts.
Have you tried a different ROM? If not, try CM7 Alpha v3. Theres nothing like CM's DSP Manager.
Make a NANDROID backup first, that way if the problem still persists, you can always easily switch back to your current ROM.

[Q] Streaming Bluetooth Audio Still an Issue on AOSP and Sense Roms - is there a fix?

I have done extensive testing with both my HTC One and Samsung Galaxy Nexus regarding the phantom ringing noise that exists on bluetooth audio. This issue is not only present on streaming bluetooth audio but also present when the sound file is kept on the actual phone (using Google Play Music). So far I have tried the following:
1) Tried multiple roms both sense and aosp - the ringing/buzzing noise still exists on both (DEFINITION - PHANTOM RINGING/BUZZING NOISE - a buzzing series of overtones that exists particularly when listening to jazz music that has a lot of ride and crash cymbals being played) As a professional musician, this can be quite annoying.
2) Tried going back and forth between bluetooth and auxiliary cable on both phones (HTC One and Galaxy Nexus), trying AOSP vs. SENSE roms, streaming vs. non streaming. Both phones and all roms have the same issue present, the bluetooth audio has a fuzzy clarity to the cymbals. It is worth mentioning that the AOSP roms are slightly better in terms of less Phantom ringing/buzzing but far from perfect.
My question is, does anyone have a fix for this? I paid big bucks to have Bluetooth installed in my car and really want to use it.
The auxiliary cable sounds good until you plug your phone charger in.....that presents an even larger noise issue. Please help.
Thanks,

if 2 phones and different roms still cause the problem then it might be your BT system.
what music player are you using / do any of them have an EQ system you can adjust.
what BT system do you have?

I am using an Audiovox Media bridge, however, I do not think that is the issue due to the fact that the issue improves slightly on the Aosp ROM. Additionally, when I run the aux through the media bridge I have no issues.
I am using Google play music. I have tried adjusting the EQ using Viper ROM 5.0 and have had no success. Any other ideas?

USB Audio

I'm using an Oppo HA-2 USB DAC with my WWE HTC One M8 and am experiencing the odd popping \ clicking noise in the audio, even when using proper USB audio apps such as Universal Audio Player Pro or Onkyo HF player. If I use "regular" players such as Gone Mad Music or PowerAmp then the issue is more pronounced.
My wife's 1st gen Moto G does not have the issue and I can use any player app and I get perfectly clear audio, so it's something to do with my M8.
I've reverted to a completely stock 4.16.401.10 firmware\rom\kernel and the issue still exists. I've tried different kernels, roms, overclocking, forcing the display to stay on, all to no avail.
I've tried a variety of source media (FLAC\MP3\AAC\OGG) which are clean (as tested on either my PC or the wifes MotoG)
The USB cable, headphones and the HA-2 itself are ruled out as they all work perfectly with every other device I can throw at them.
I've spoken to Oppo (the audio company, not the phone company) and they reckon it's an issue with Lollipops memory management, but I'm not convinced.
The audio from the headphone jack is pop\click free but the HA-2 sounds so much nicer it'd be a shame not to use it.
Has anyone else come across similar issues with the M8, or even better, come up with a solution?
No, but since I lollipopped my M8 the audio on Bluetooth stutters and clicks how you've described

Sound issues with 3,5mm headset on usb c (adapted), electrical crack on (un)plug then

Hi
just set up the device and all went fine, trying youtube music for the first time.
after some seconds the music disappeared with crackle sound through ehadset on highest volume.
unplugging and replugging the 3,5mm headset through adapter that came with device on usb c there was an electrical crack sound in the headset when un- and replugging.
closing the app and relaunching worked for a short time then sound disappeared on one ear. same crack in ears on (un)plugging.
second headset no difference, but then it works without any issues when using headset volume just one step below max volume.
so this is a known issue on that device, software thing or hardware thing?
evreything else is fine, should we cross check built in speaker on highest volume for crackles to chekc the hardware or do headset through usb c and built in speaker run throught two different output stage/amplifier circuits?
thx for any help
Yea this is happening. There is another thread here also talking about it. It drives me crazy... Seems to be software related (hope so), as some people said installing another rom solves the issue. I also noticed (at least until now) that the problem seems to involve instagram, everytime I had this issue, I checked and instagram was opened on background. I don't remember having the issue when I close instagram beforr plugging the headphone. Not sure about the relation though, still needs to test more.
I will install xiaomi.eu rom soon to test if this happens there also.
Btw, what miui version are you running?

Whatsapp aswell is a big issue. Some people said replacing the typec/jack adaptor works.. but i dont have another one for the moment to test.
ah, just saw the other thread, 2 sites already
so at least no hardware issue, at least not the device, maybe the adapter
thought about buying bluetooth or usb headset anyway as i think even if only some grams the 3,5 on the adapter always tears a little bit on the cord/usb c plug over weeks/months/years and might affect the port
after a restart and reinstalling youtube music i could not reproduce it anymore
have been listening half an hour music without any issues and had a phone call another 25 minutes with headset without sound issues
running global version with
global 10.2.9.0 PFBEUXM
while PFBEUXM should stand for eu anyway?
is there a way to flash another official rom without rooting/unlocking the device and loosing warranty?
thx

[HELP] New PCB doesn't work

Hi there folks,
My mic audio quality became very crappy, I've tried changing ROMs, cleaning it, but no success, so I bought a new PCB (the one for charging, mic, speakers and P2, not the main one).
I installed it and charging seems to be working fine, but no audio comes out from the speakers and the mic records audio in a very very very low volume (only in my PC with my speakers at high volume I can hear something).
I think it's software related, but I don't know where to start. I don't want to flash my ROM again because I did it this week already, I'm running Havoc OS 2.9 with Magisk, is there a way to fix it from system or recovery? Like reinstalling drivers in Windows or something like that.
Thank you in advance.
