Crackling sound on Bluetooth. Cm10?

Whenever I pair my gs3 to a Bluetooth device and play music, I get bad crackling sounds. Is this cm10 problem or hardware problem?

I have the same issue on OTA non root JB. Motorola headsets S10-HD and S305 both have the same problem for me. This is very discouraging as they worked great with CM 9.1 on my last phone (G2)
Was hoping to find out that CM 10 was better.

Change your govenor to performance. It helps. And for CM10 I used faux kernel and got the least crackling. Or set a profile with set cpu like I did when using your favorite music player.

CM10. CM10 did not have BT support until recently, and its buggy at best.
Run stock and all your devices' features will work.

It might have to do with the bt bass bug. It was fine on earlier nightlies, but it started happening about 2-3 weeks ago. You can test by playing music, then call someone real quick and hang up. Your music should resume with full range of sound frequencies.

Recent ROMs that depend on DSPManager have terrible audio quality

Has anyone else noticed this? I've tried LiquidSmooth RC8, the latests Paranoid Android, and the newest SlimROM. They all must be based off the same ROM, because audio quality is equally horrendous. I notice that in the Settings > Sound that there is an option to select between MusicFX and DSPManager. However, none of these applications seem to have any affect over the audio, whatsoever. I am surprised that the BASE audio wouldn't be the same as every other ROM. Shouldn't these EQ/DSP add-ons just allow you to modify the stock flat-EQ? Most people would probably want a flat EQ anyways, because their audio ends up on the car stereo, or some other device that already has these controls.
With that said, are you guys noticing the same thing? I absolutely cannot get Pandora or Spotify (haven't tried any others because I don't care,) on these new ROMs. I hope this isn't what the latest CM10 offers, because I am about to flash to that now.

Oh man, I just loaded up the latest CM10 stable and it has the same problem... At least DSPManager can modify the EQ for the entire system, not app-specific. Even still, it sounds nowhere near as good as it did before. While I'm flashing my phone I am playing feeding the same Beacon "The Phoenix" audio cube on my desk with my Transformer TF300T and it is shaking the whole surface with bass, and sounds very full. I played with all the EQ settings, and went manual and got nothing remotely close using my S3 with these ROMs.

Just restored my CM10 11/7/2012 nightly and it has flawless audio over bluetooth--but other issues like missed calls, etc

You silly op you.that's backwards dspmgr is simply part of the general aosp experience and all aosp roms recently developed that bug

I dug through quite a view AOSP-based ROM threads and could not find anything. I don't understand how anyone could possibly use these ROMs with that horrifying bug?

Freeze or uninstall DSPmanager then install a new audio engine (I use team AC!D's), problem solved.
EDIT: I've never had that happen before but I always freeze that app and I've been using AC!D audio mod since the beta for this phone.

Hate to say it but it's unrelated and all over the cm10 thread

I just bought power amp and all of my songs are extremely low quality. This doesn't seem to be a problem on aokp for my cousins s2. Wonder if its an s3 only deal.

Its terrible...I cant even use any of these ROMS because of this!

I don't have issues over wire, but Bluetooth is borked in aosp. Due to the transition to 4.2 don't expect quick fixes so.... I moved to a tw rom mainly because of bt and ril related battery drain.......

Is this supposed to be a 'feature?' If so? They should remove DSPManager and let us decide. I would always prefer some flat EQ so that I can process it elsewhere.

I have 2 sg3's one Jelly Bombed and one CM10 based. Side by side TW BT sounds better. 1 fix for CM10 is after starting BT audio go to your phone and make a call (I just dial 123) then hang up as soon as it connects. Viola, bass is back and audio is tolerable... hope this helps you out

crackling noise on Headset and speakers

so recently my samsung galaxy s3 has been making a cracking noice, at first i thought it was the headset i had so i just switched those out, but it didn't fix the problem.
My phone is rooted and im running a custom ROM
is there solution to fix this?

If it's not your head phones it could be the head phones Jack
Google for a way to clean it
Also you could have messed up using a mod like bats audio app or volume plus

Are you using Bluetooth or what kind of headset? And what ROM are you on?

the tom i am currently using is JellyBomb ver. 13.0.0 [LJ7], also im not using Bluetooth im just using some Skull Kandy headset and Beats Audio Head set and they both have this cracking noise, yet when i use my other Samsung Galaxy S3 it doesn't make the cracking noise, so i have no clue if my current S3 is just creating this noise for no reason.

Are you using volume+? That app has caused me audio problems in the past. I would check DSP levels too, make sure you don't have anything jacked up to high.
Also, are you using any other sound processors like Beats audio? I really feel that your culprit lies somewhere in the sound processing and/or settings. And from my personal experience I recommend staying away from things like Beats and V+.

I wipe and clear everything then re flash my phone but I keep getting this noise.

[Q] Bluetooth Pairing With Car

Hello All,
I've tried to pair my phone with my Honda Accord's bluetooth system but whenever I stream audio there is a lot of feedback and static noises. However, if I am on a call then the audio is fine. I'm currently running Darth Stalker X2, I've tried multiple versions of the rom, other roms (including aosp) and kernels, odin back to stock, and I still receive the same results. When I tried to stream music with a htc sensation everything was working perfectly. So I don't think my car's system is the issue. Is there something I missed, or is my phone's bluetooth probably messed up? Any help is greatly appreciated.

I had the same issue with my bluetooth all I did to fix it was using rOM Toolbox to adjust the CPU slider.

so you were under-clocked and you moved the cpu slider back to "full" and it worked?

Yes

Audio plays through both phone speaker and Bluetooth speaker

Just like it sounds, audio plays through both outputs at the same time. Now this only seems to occur with phone audio like notifications and system sound, not media sound. Gave not tried game sound yet.
On CyanogenMod 4.2.2 with the latest Franco.Kernel nightly on my toroplus. Never had the issue with stock
