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.

Stuttering music

Hello folks,
I got my galaxy note 2 for 3 days now, but when I want to play mp3 music then the problems come. Music is stuttering all the time. I'm not using bluethoot or anything like that. Has anyone too this problem or a fix?
Cheers,
Ramon Smit

Do you have power saving mode activated? (Not saying that is the problem for sure but please check)

Nope, I have everything checked twice. I noticed when i upload my music to dropbox the quality is not stuttering. But when I copy my songs directly from my pc trough usb to my note then the problems are gong to come up.

There is some problem with your speaker. Better get it replaced. I suppose you are getting it normal when you listened through the ear phones.

Problem is also there when I use headphones. Its kinda like digitslisation in the sound. Its really weird. YouTube doesnt show as any problems at all

Funnily enough, I noticed a stutter on some music tracks today when using the default music player.
My mp3's are stored on a 64gb class 10 SanDisk sd card if that makes any difference.

I'm using player pro ... for my music player ... and I had this happen once .. but it was some bad mp3 files .. Blahhhhhhhhhh

I'm having this issue too using the beta of n7player. Don't know if it's player's fault (youtube audio seems fine), or it's something related to custom kernel/rom :S

Possible, but i'm still running stock kernel, rom and radio. I think i'm going to the store and maybe they send my phone for repair. I'll keep you guys up to date

Mmm, just noticed, mine is a bluetooth issue, motivated most likely by the custom kernel/rom I'm running..., the shuttering gets worse if I move away from the phone, anything beyond a couple of meters == no sound at all.

im having this problem also
i havent identified why it is but im getting alot of dalvikvm concurrent and for_alloc freed in my logs
things i've tried:
overclocking
set the minimum to 500 mhz
changed cpu govenor
another music player(winamp)
removing any games that i've installed
and then i flashed it with a custom rom, and i still get lag spikes ;/
http://pastebin.com/XQJNyVng
the lag comes when the dalvikvm shows up in log
i notice that it only happens when the screen is off

auto memory manager (play store) and set "empty apps" to 250 - its better but still Some stuttering

The auto memory manager fixed my probleem! I'm glad it fixed the laggy songs! Thanks!

Hi,
Read on one of the threads that when you transfer songs in bulk to the SGN2, they stutter, but if you transfer in batches of 5-6, the same songs play well.

yeh same problem here with stock music player :/

I have the same problem using the stock ROM and music player.
The stuttering seems random, and I have plenty of free memory (~750MB free).

yeh for me it is also random, sometimes i have listened for 2 hours music without stutters, later i get 1-3 stutters at one song. Especially i get stutters when screen is off or surfing the net. Noticed stutters at 4.1.2 firmwares, hadnt any problems with 4.1.1

I'm still on 4.1.1 actually.

Hmm I'm back to this problem. Stock Rom/Kernel. I'm rooted now.
Used the memory manager but the issues are still there. It's really weird. Did put them one at another on my SDcard trough USB.
When I zip my files put them on Dropbox and download them from my Dropbox then there is no problem..
Almost would think that the drivers are screwing the songs up in 320kbps.

Which ROMs have working BT streaming music?

Just purchases some Jay bird blue Bud x headphones only to realize cm doesn't have Bluetooth fixes yet. I'll go back to cm when it's fixed but I need my music for running!

It's your lucky day. It was fixed on CM today.

No it wasn't. Calling works on Bluetooth but others also reported music not playing.
For me, every time I connect the Bluetooth headphone my phone slows and eventually ill have to reboot because of no screen wake

CM 10.1 20120203 - BT audio fixed, according to 30 people in the thread. Unless I can't read. Did you wipe cache/dalvik?

Yes. I did a clean install... I just went back to the thread to make sure I'm not going crazy. Two or three pages from the last post some people explained having the same issue.
I can get the music to play fine until the screen goes off. Then I'll have to restart the phone. I've already tested it 4 times and still get the same results.

I don't know why Samsung would release a phone that doesn't have working BT, I mean they got past all their issues with their first couple releases of phones lol.

The only BT device I have are my headphones so I don't have anything else to test on. Just downloaded stock ROM and I'm going to test it.

If you want aosp rom illusion 1.2.1 has Bluetooth working for both audio and media. Tested by me.

[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
