5.1 ROM with working bluetooth, any help? - Galaxy S III Q&A, Help & Troubleshooting

My sister-in-law Galaxy S3 was getting old, so I installed for her Temasek 12.3 rom, and she loves it very much, except that she depends a lot on Bluetooth for car/headset, and with the default ROM and kernel the bluetooth is troublesome: freezes, doesn't work always, needs a lot of reboots.
What ROM/kernel combination can I put to have a stable device with a working bluetooth?

@mcbyte_it: BT stays an ass-needle in LP. You'll have to test various ROMs & your hardware. For 100%working BT go back to JB: NCS-ROM is based on newest firmware and hardly debloated. So very fast & batteryfriendly. Perhaps you'll miss same little LP-features of courseā€¦

[Q] Bluetooth and custom ROM

I have tried both Froyo and CM ROM (2.2) and both are stable except for bluetooth. At least for mediasound. The headset connects fine, but after a while disconnects. Sometimes the telephone sound is still available, sometimes not. Can anyone recommend a custom ROM with stable bluetooth experience? What about the Gingerbread ROMs?
I've had the same problem, its annoying when you're driving and try to answer the phone, but all they can hear is your pocket
anyways, i used this http://forum.xda-developers.com/showthread.php?t=947613 rom for a while, and haven't come across any problems with that one for a few weeks
I got the cm7 rc2 v009 rom now though, havent had any experience considering BT yet
my wifi or bluetooth disconnects all the time. I can only have one at a time :S

Same issue here, with all 2.2 and 2.3 roms Using BT with WiFi disabled works fine. Also Blade's WiFi fix makes things worse while it reconnects hung WiFi connections. Some radio\"driver" problem.
Hope to see a fix! Ill investigate it myself when I have some sparetime.
edit: Try the following mentioned by Wolfbreak;
Bluetooth issues:
1. Try this App [ http://www.foogod.com/android/ ]
2. Download APK and put on your SD Card
3. Install with a File Manager

[Q] Bluetooth audio streaming over WIFI

Hey all, I've been lurking around here for a while. I'm currently running CM 10.1 using the N4 conversion and I've been really happy with it. My only problem I've had is when I try to play A2DP bluetooth audio with something streaming over wifi, the wifi disconnects and switches over to LTE. Sometimes it reconnects quickly, others time not at all. Then it proceeds to disconnect and reconnect wifi constantly making it unusable.
I read that other N4 users with 4.2 were having this issue and it was supposed to be fixed in 4.2.2, which I'm running. I also had this problem with the korean 4.1 port. It worked fine on stock ICS.
Are other people having this problem? Should I try a different rom? I really need a jelly bean rom because I have some apps that I've made for business that use 4.1 features (expandable notifications).

Cyanogen MOD 10.1 ROM Bluetooth Isues

I really want CN 10.1 on my rooted HTC One except the bluetooth connection with my Ford SYNC system is awful. I've tried other ROM's that work but they are missing features of CN I like. ANy fixes out there.

[Q] USB Audio out using CM11 Dev

Hello,
I just installed the new dev version of CM11 for my i777 from here:
http://forum.xda-developers.com/showthread.php?t=2559694
and was hoping that it would have fixed USB audio out that CM10.1 didn't appear to have and that others have stated that is disabled in the latest stable release.
The cable that I am using shows "Car mode enabled" when plugged in but when I attempt to play any audio, it still comes out through the phone. Is there any way to enable this functionality, maybe with a different kernel or maybe modifying system files?
Any recommendations?
Thanks!

So I did some major researching and found a solution for anyone interested. It seems that only Android version 4.1.2, packaged in CM10 (not CM10.1 or later) work great with usb audio out on the i777. Not quite sure what happened with CM10.1 or later that broke usb audio functionality but I hope it comes back in the later releases.
Some report that CM9 will also work.
Here's a link to CM10 builds if you want to experiment:
goo.im/devs/cm/i777/nightly
I installed cm-10-20121217-NIGHTLY-i777.zip which looks like the last CM10 build before it goes to 10.1.
So far so good, but it's only been a few hours so far...

Current State of Bluetooth: 5.x.x and 6.x.x ROMs

How are Android L and M ROMs handling Bluetooth connectivity, both for audio and talk?
I'm wondering specifically about CM12, CM12.1, and CM13 based ROMs vs AOSP, AOKP-based ROMs.
What are Verizon S4 users' best choices for stable Bluetooth 2 & 3 performance on Android L and M?
I'm using OctOS, specifically OCT-L-M6-FINAL-5.1.1-20151229, and Bluetooth more or less works but I have run into a few Bluetooth Share FC's over the few days I've been testing it so far.
