Annoying noise in background - One (M9) Q&A, Help & Troubleshooting

Mates,
It's been a while that I've noticed that there's sth wrong with my m9's sound:
1) jitter (bonfire-sparkle-like sounds) and hissing when I'm recording audio via the native app
2) Boomsound speakers playback too noisy and hissy sound
3) whenever I connect my phone to the car stereo via USB (the pioneer Android support model), the annoying jitters occasionally show up
I've tried multiple hard resets and running the latest Android on my phone. As far as I remember, it wasn't like this the first day.

[Q] Audio output with acoustic noise cancelling

Hello all, I've got a pair of noise cancelling earbuds (Audio-Technica ATH-ANC3, if it matters) that I've been using to listen to music all the while. With the One X I realise that when noise cancelling is on, a lot of static is introduced in the background. Switching it off makes the noise clean (but then I don't get to remove background noise)
I did a bit of testing and found that this affects only music (or radio) playback and that system sounds are not affected. Furthermore, enabling or disabling Beats audio will affect the texture of the noise. I've played back music using the stock Music app, PowerAmp as well as PlayerPro. Therefore, I am thus inclined to believe that the static is introduced somewhere in the audio pipeline. I've tried installing http://forum.xda-developers.com/showthread.php?t=1636914 with CWM to see if replacing the audio filters would do the trick... but it doesn't.
Any clues to remove all filters? I'm currently running a rooted stock 1.28/CWM.
Thanks for any help.
Oh, and if it helps, I tried plugging the same pair of earbuds into a HTC Sensation (the vanilla edition) running ICS and it doesn't have the problem.
Another thing I discovered: if I take the output of the phone, pipe it to my computer via Line In, then listen to the audio via my earphones with noise cancelling on, I don't get the static.
Perhaps there's some frequencies being generated by the phone that's not agreeable to the noise cancelling circuitry? Plugging it to my desktop would filter those frequencies?

[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?

Weird Audio issue

Has anyone noticed something similar with their LG G4?
When playing music, or podcasts, using different apps (eg CloudPlayer, GMusic, Pocketcasts) via bluetooth in our newest car (Honda Civic '14) I get a noticeable scratchy electric noise now and again - sounds a bit like an old jack cable that needs some cleaning.
Weirdly though, when I use the G4 in our other car (another Civic but this time a '10) which I don't have bluetooth set up for - but rather use the headphone jack and AUX on the car. This also has some weird noise issues on the left channel too. Not like the sound on the other car - but this is amore obvious distortion/static/crap. It's not a continual noise like an out of tune TV (like you'd get in the old days), but it's a frequent intermittent noise.
Do you think this is due to the G4 - or what?
It seems weird to me that in the two cars there are similar audio issues, via different input sources.
Coincidence?
I haven't tested either car with other devices yet - but before I do, I just wondered if someone on here had experienced similar.

Had the issue on g3 my fix was when i use music i had to turn off all other sounds even screen toich sounds
"i had to turn off all other sounds even screen toich sounds "
I don't understand. I don't have any other audio on as far as I know when the bluetooth is on.
Are you saying that the phone needs to be set to silent, in order for bluetooth streamed audio not to be affected?
The thing I find weird is that it's only the left channel which has issues - right channel seems perfect.
And this is both for when using bluetooth, or minijack cable.
Why should only one channel be affected?
I've got same issue with sound via bt in my car with a parrot receiver. Scratches for a few secs after connection, then it stops. But continuous scratchy sound when using gmaps or waze

Static / white noise while playing audio via Aux cable

I have experienced substantial static noise on my Sprint variant of the Samsung Note 7 when using headphone jack to Aux in my car stereo. The static's volume was substantial and made listening to music unbearable. I was thoroughly disappointed that this brand new phone sounded like garbage, and thinking it was a hardware defect and considered returning the phone. I decided to troubleshoot this problem, and found an odd solution, odd because it seems to be a software issue. So, while my phone was streaming music and producing static while plugged into the Aux car stereo, I jumped into settings and toggled on the 'UHQ upscaler' found in 'sound quality and effects' at bottom of sound settings menu. (( Settings > Sounds > (Advanced) Sound quality and effects > UHQ upscaler )) Toggling this switch immediately got rid of the static issue... even after turning the toggle back to off.
Static / White noise Experience Continued....
So, while listening to static free music via Aux cable to car stereo, a call comes in through phone app, static immediately resumes as phone app takes over sound settings. I answer the call and static continues to come through car speakers obscuring the caller's voice. (no, this is not static from a microphone / speaker feedback loop) So, I unplug aux cord and place phone against ear the old fashion way. When call is about to end, I plug Aux cable back into phone, static resumes until phone call ends (phone app releases control of sound) at which point music resumes playing without static.
Troubleshooting methods tried while figuring out static via Aux cable to car stereo:
- plugging in various Aux Cables ( no effect )
- unplugging charging cable while listening to music ( no effect )
- playing music on Note 7 to home stereo via 3.5mm to RCA cable ( Did not produce static )
- toggling UHQ upscaler (( eliminated static via Aux cable to car stereo after toggling on (or off, after it has first been toggled on), static returned for duration of native phone app call and disappeared after call was over ))
I find this issue to be quite odd, seems like it is some sort of software issue... Is anyone else experiencing this or something similar?
STATIC!!!!!
Edit: After doing some more research found that the galaxy S7 and S7 edge suffer from same problem. Workarounds include toggling UHQ upscaler ( Settings > Sounds > (Advanced) Sound quality and effects > UHQ upscaler ) and/or purchasing a Ground Loop Noise Isolator...
The sound on my note 7 is fing horrible especially on the aux line out, the bass and treble is so muddy. i don't get near the clean volume or loudness like I do out of my note 7 compared to my iPhone 6s even over Bluetooth. I'm wondering if there's a volume protection setting on the note 7 I'm not seeing because even my UE mini boom sounds louder and better over Bluetooth with my iPhone.
Galaxy 8 hissing noise
My Galaxy 8 makes a huge hissing noise when I hook the audio jack to an external speaker with the 3.5mm plug.
Samsung engineers are incompetant.
Samsung brags about all these hundreds of "features" on this $650 phone and THEY CAN'T EVEN GET GOOD AUDIO OUT OF IT.

Strange thing with sound recording

I accidentally discovered strange thing while recording the sound via external microphone (the headset that came with the kit) in default recording app and camera app (maybe in other apps too).
That's what it's all about: when i plug the heaset 3.5mm jack in, the message pop up: "External microphone will be used to record audio". Ok. But! The sound can aсtually recording from extenral mic only if you immediately start talking in it, otherwise it will be recording only from internal mic! Is it a bug or feature?
P.S. And the second question, maybe it stupid:
I tried to record sound from Nintendo switch to Galaxy S9 by connecting them via 3.5mm cable (male-male), the sound did not recorded Now i know it was useless, but is safe for both gadgets to connect their 3.5 ports?
