[Q] Q Audio Reset - Nexus 7 Q&A, Help & Troubleshooting

I was getting horrendous distortion from my speaker and assumed that it had somehow blown. I'd never installed any volume enhancing apps and to be honest had just decided to live with it.
I then connected to my Jambox via Bluetooth however the delay was handicapping me at songpop (yes I was that bored). However when I switched off the jambox and the internal speaker kicked in my distortion was gone, and noticeable quieter.
The question is does anyone know of any apps that have self-contained volume boost that might have caused this?

Hissing/static noise everytime G1 plays sound. Both speaker and headset. Just me?

I have a noise problem, I don't think it's quite the same as previously posted noise problems.
I get a hissinh/static noise from the phones speaker (on the back) and from headphones. It is only happening while the phone plays sound (and some seconds later). Every time I up or down the sound with the volume keys, there are noise coming out of the speaker for some seconds. Please report if you have the same issue, especially eith headphones.
I could live with the speaker-noise, it's not that big a deal.. What's worse is it is in the headphones. I have a quite low impedance set of in-ear plugs from creative (I am able to hear the hard drive spinning up in my old mp3-player, but no constant noise) Crap. I want to use the phone for music listening. Question is: software or hardware related? Using JF 1.51 ADP for the record
I hope it is hardware related - I bought mine off ebay, allthoug brand new and everything, I don't know how I would go about getting it fixed/a new one with no receipt. Shipping it back and forth to England isn't really tempting either.
It's not just you, it's piss-poor rf isolation on the audio outputs. Listening with bluetooth doesn't solve the issue either as bluetooth has its own noise.
Yeah, I have yet to listen to a decent pair of BT headsets.
So this is a known problem, and it's definitely a HW issue? The fact that it's only there when sound is played, and is also there with a headset (where shielding around connectors is not and should not be a problem at ALL) made me hope this was softwar related. Argh, what to do then? The sound quality despite this seemed prety decent, although a headache today prevents me from really listening to music and say for sure. Shame.
*Pondering refund options.*
Any chance of isolating around the connector and fixing this, if it is "airborne" caused noise, or will the noice enter the equation before the connector (cabling, sound chip)?
I will try with a relatively high impedance headset (sennheiser 555) and see if it is better there. But can't take them on the bus anyway. But a couple of Ωs could always be added somewhere along the cable and might do some good. Have to have the sound at the lowest levels with the in-ears. Maybe a software fix to lower the volume output will help? Or won't it, if RF noise is the cause?
red: I will buy this item and hope it helps. And will look into lowering the volume output when using headphones as well. Should be possible (atleast it usually is with tweaks in WinMo.)

[Q] Nexus 4 random freezes and headphones sound is distorted

Hi,
I have been having random freezes which force me to power boot my nexus 4. These occur mostly when I'm having phone conversations or using Skype, but also when I listen to music using my headphones.
Also, the music from the headphones is all distorted, as when you play very loud music from very crappy speakers. These two problems started at the same time.
The music sounds fine when played from the phone's speaker or when using bluetooth. I have also performed a factory reset but the problems are still there.
When I try to replicate it whilst monitoring with adb logcat, the freezes never occur, which leads me to believe my battery is messing up the electric system
I'm running stock android 4.4.2
Please help!
I've replaced the headphones module nut the problem is still there. The internal speaker audio is also messing up, it's all distorted, but the loud speaker seems to work just fine. I really have no clue what is wrong with it.

Extremely low Bluetooth volume?

I swapped from a Nexus 5 to the 6P, and I'm finding bluetooth volume to be incredibly low. I basically can't hear my audiobooks in the car with it being as low as it is. This is a serious problem for me. I have the volume maxed and it's like a whisper.
Is anyone else experiencing this? Is there a way to boost the volume? My bootloader is unlocked, but I am not rooted yet.
I have had the same issue. Car was fine, but my sound bar was SUPER quiet. I had to delete the sound bar and re-pair and it was fine.
I have also had issues where the sound coming out of the phone was super quiet, I had to reboot to get that to resolve.
I think something is wrong with the bluetooth on my phone. I am contacting Google.

[HELP PLS]Audio distortion over headphones

Hi,
I've just bought a pair of Sennheiser Momentum Headphones for the Galaxy series (M2 IEG) and i'm experiencing some very weird distortions.
Best description would be a compression effect, taking out all the base and highly accentuating highs and mids.
First thing i though was there's some handsfree sound option, like a voice preset, that gets activated if there's a 3 pin 3.5mm jack detected, but i can't find anything.
I've tried the following permutations:
- New headphones with PC soundcard and with older HTC One -> no issues (other than volume up/down, next track etc commands were mixed up on the One)
- S7 with another pair of headphones -> no issues
- switched on/off pretty much all audio settings on S7 (equializer, surround, upscaling, adaptive sound etc), factory reset -> no change.
What i did notice after a factory reset was that when i started the first track, it worked fine for a few seconds, then the sound got distorted as soon as i turned the volume up (timing might be a coincidence). This leads me to believe it's a software issue. Maybe i'm blind, but i can't find any more sound options to change.
Any help would be highly appreciated.
Thanks
This is strange. Never heard of this as a software issue with any device. The description of ur distortion almost sounds like when I dont put the headphone fully in the jack. Could a phone case maybe be preventing the jack from going fully in? Otherwise I'm at a loss.
I managed to fix it, but it's a weird one.
I cut a thin strip of scotch tape and isolated the bottom pin on the jack, so that the remote commands were blocked out. As i was expecting (since the remote commands are the only difference between these headphones and the other ones i tried), it worked just fine.
What i didn't expect was that after removing the isolation, it kept working fine. I am now several reboots and updates later and everything seems to be ok.
Maybe someone more tech savvy can figure out what it was, because i sure can't.

Both speakers playing?

So my phone took a tumble very soon after I got it and I've noticed that when playing audio, I get sound coming from the earpiece as well as the main speaker. At low volumes it's basically a distorted rumble, but somewhat clearer when the volume is higher.
Also during phonecalls the earpiece is noticeably distorted unless the volume is set to 1.
At one point when adjusting the volume via the slider, I was blasted with a bass frequency, forcing me to restart to make it stop. Not sure if this was the cause or effect.
Is media playback meant to utilise both speakers?
Any tips on troubleshooting this issue? I get the feeling the hardware may have taken a beating but hoping there's a fix that doesn't involve me sending my phone away.
Tia.
Yes, both speakers are used, but these have different frequency range as far as I remember.
