A2DP Bluetooth on 2.1 Based Roms - In search of a final answer

Hi all,
Apologies in advance if this is in the wrong forum, but it does pertain to the array of 2.1 ROMs out there.
I am in search of a 2.1 based ROM that has fully functioning A2DP stereo bluetooth capabilities.
Ive used Fresh 2.0d for a long time (still do), tried DamageControl 2.08 etc.
Only one that I had some success with was DarchLegend v5.0.5, but it seemed to have problems getting my contact pictures from Facebook etc. (Admittedly I may have to try it again).
My question is whether anyone can recommend a ROM where A2DP is known to work perfectly?
Also, a more general question: are ROMs like Fresh and Damage Desire-based as opposed to Darch being Legend-based? If this is the case, what are the benefits of a Desire-based ROM over a Legend-based ROM?
(I fully admit that I don't know enough about this stuff...I've tried to search but am still in need of answers - please help a curious guy out!)
Thanks for all the help

I've used an a2dp stereo bluetooth (Blueant X5i to be specific) with the ZenEXP (mytouch based) rom, with Fresh Toast 1.1 and with Fresh 2.0d. ZenEXP seemed the best to me, but they're all glitchy. Slacker works fine with the headset. Pandora will stop playing music over it after the screen turns off. I don't use the built in media player so I can't say how well that works. NPR stream & tweet and iheartradio both worked with it just fine too. If it gets a hiccup though, it'll stop the audio and the bluetooth will get stuck saying it's disconnected and it won't reconnect properly until you restart the phone. Pandora did this any time the screen turned off.

Just yesterday I upgraded the firmware for my blueant Q1 and streamed some audio from slacker just fine. Also checked htc music app and worked too. Ill do more extensive testing tonight. Im on Damage control v2.08 which is a sprint hero based rom.

I notice that both of you above are using Blueant...
Here's my problem...I have both a Jawbone ICON and Bluetooth Stereo speakers in my 2010 Mazda.
The Jawbone seems to work fine when I upgraded it to support A2DP, but I just don't really like it because its quiet and outputs just through one speaker (obviously). My Mazda is the one Im really trying to get working...it worked flawlessly on a 1.5 based ROM (proving that the speakers/bluetooth in the car itself works)...its just on these 2.1 based ROMs.
Any ideas?

I have a 2010 Mazda 3i with bluetooth that worked fine with android 1.5 but the audio is messed up with android 2.1, it plays at 2 times the normal speed and will randomly slow down and sputter at times. I am thinking about rooting my phone in a couple days and playing around with the bluetooth files if possible since you aren't having any luck with any of the 2.1 ROM's out there

bluetooth
My phone worked perfectly on bluetooth in my tacoma with car m_media. Since 2.1 it works sometimes. The sprint store told me it was not the phone which I know it is and I should get a newer bt device. It was new last year. I have now found if I go into airport mode for a few seconds and then go back the bt will work until I get away from the truck again. I have to do the airport thing everytime I come back, but it will work.

Jawbone A2DP update
Anyone with jawbone can now use earphone as headphone for 'any' media from Hero, http://mytalk.jawbone.com/jb2/mytalk/beta, hope this helps!

Froyo - back to older radio because of A2DP

Had issues with Froyo and streaming to my car's Parrot MK6100 handsfree. Audio would cut and then skip. I switched back to the older radio (and broke video recording ATM) but now streaming works great again. This was a real show stopper for me so now that it's fixed I'm happy again.
I opened a seperate thread so this does not get lost in the radio thread in case someone else can use this info.

That's interesting. I'm using FroYo, with the updated radio (4.06.00.12_7) and haven't had any of the issues that others have been having with the new radio . I use a Motorola S9-HD bluetooth headset and haven't had any issues with call quality or streaming music.

I haven't had any problems with my Pioneer head unit in my car, either. Works perfectly.

same with my sony unit, no problems at all

The new radio is much better for me with A2DP.. I could only get it to connect about 1 time in 3 with the old one (causing much frustrated switching on and off of bluetooth until it worked) and now it works 95% of the time.

Well, streaming to my BT headphones was OK with both radios so I guess it's some incompatibility between the N1 and the Parrot MK6100... It would seem to me as if their sampling rathe was incompatible, causing buffer overrun or underrun (it would happen at fixed intervals). Guess the MK6100 is to be blamed (last time I am buying Parrot products anyway).
Other than that - no issues with any of the radios.

Crackling bluetooth

Hi all,
I have the Plantronics Discovery 975 bluetooth headset which has never given me problems before on previous HTC phones, but I now hear crackling whenever someone speaks...
Are there other bluetooth headset users with the same problem?

+1 voyager pro sametimes cracle sometimes no

We bought two SGS2 and two Plantronics Discovery 975 Bluetooth headset at work. I got one of the phones and one of the headset and I'm having the exact same problem as you have. My other colleague who were happy enough to recieve the other phone does not have any cracking noise which is rather weird.
I even tried my headset connected to his SGS2, i had to make sure my head wasn't messing up the signal or something lol... and it worked fine, so it's something with the phone i guess.
In this thread they talk about KE7 having a new sets of Bluetooth profiles and what not. Perhapes Samsung recognized there was some bug and changed things around.. But i'm only guessing here.
In case anyone is wondering:
Yes, both phone and headset was fully charged when tested.
Yes, both phones and headsets were tested in the same room around the same time so it cant be interference from external sources as it didn't bother the other SGS2.
I'm using KE2 over here. I forgot to check what version my colleague is using but we got the phones the same day from the same store so I bet he is using KE2 as well.

Did both phones have WiFi enabled or disabled?

Come to think of it, I think i had it enabled on mine but not on the other phone. I'll try compare them again and this time have wifi off on both phones.

I had a 975 for about two weeks before I returned it. I wasn't getting consistent performance on either my G2 (HTC), G2X (LG), or Vaio P (Sony). I replaced it with a BlueAnt Q2 and didn't have any problems with the same devices. It works really well on the SGS2 for phone, media, and Voice Talk. The 975 also wasn't A2DP and I like to listen to music and audio on my headset sometimes.

I tried disabling the wifi, not sure if its just now or not but, it seems to be working better. I still hear the crackling noise every now and again but not like before. However i think i will keep using my SE MW600. It delivers more solid performance and the sound quality is better as well. Maybe it's because the MW600 supports A2DP.. i cant really tell.

HTC HD2 Tmobile USA I am also having serious crackling problems...to the point of contacting Plantronics to replace my Voyager Pro and pay $49 for refurbished headset. Distance to phone 2 feet and only getting 1 bar on bluetooth strength. Any sort of obstruction like moving head between headset and phone still at 2 ft away...noticeable crackling and 1 or less BT signal strength on phone. With Wifi enable crackling increases. Connecting to a linksys router just 3 ft away is quite fast but still only 3 signal strength. Turning off bluetooth causes a rise in wifi signal strength but zero bars if more than 10 ft from router. I hard reset but problems still existed.
Extensive research on the problem came across issues about bluetooth and wifi electronics on circuitboard are side-by-side and has something to do with the negative affect on each other.
Anybody have similar "crackling" audio or crackling sound and / or LOW signal when close to phone or wifi routers. I welcome any suggestions at this point.

Jawbone and bluetooth crackling
Hi,
I have a Jawbone Prime which I used for my iPhone 4, which was crystal clear, now I've used it a couple of times with my S GS2 and so far I'm struggling to get a clear call quality.
I thought it was the headset but I have tried it with a friends Advantax speakerphone and that happens the same, every 10 sec's it goes quite and crackles to the point that it's impossible to actual have a conversation!
My phone is only 3 weeks old is it worth exchanging it or will I get the same problem if its a software issue??
Help please
BTW I have just spoken to a lady from Samsung about this issue, to find out if it is a handset issue or software. After being passed around saying it was the headset, though I explained I have tried another 2 headsets, she now said my headset is not compatible.
When I asked her for a list of compatible headsets she put me on hold and then came back saying 'Please go to an accessory store to find out'.
I don't like being fobbed off but I believe Samsung are doing that to me and everyone else! I asked if they were fixing this issue, as there are other forums of this issue, she couldn't answer that question funny enough!
I'm now going to try another handset with my sim and the headset as I work in CPW, finger crossed!

I don't know if I am having the same issue as you guys. You are describing it as "crackling"? My connection falls into a state where the audio sounds as if the bandwidth is REALLY low. So the other person's voice is choppy - really fast choppy - I don't mean intermittent sound.
If I briefly transfer the audio to the phone and then back to the handsfree device again it clears up.
This happens in my car which has a Parrot CK6100 and also our BMW mini built-in bluetooth system.
I have a UK Orange branded SGS2 with KE2 firmware.
Could someone try doing the above and see if it clears up the audio?
As a side issue, stereo audio over a2dp works without problems so it is not a signal strength issue.

Better with wifi off, but still crappy sound.

I have been having a problem with my bluetooth crackling in my car for a very long time now. I did a search and found this very old thread. I wanted to bump it up to see if anyone else is having a problem like this and if there is any known troubleshooting steps we could take. As previous people have posted, stereo bluetooth works fine, its just on calls with my car that it intermittently crackles. I can toggle the connection to my phone and back to my car to clear it up, but who wants to do that? This happens nearly every call. I thought it was my car so I ignored it but I recently tried my phone in a different car and had the same issue. Ironically, I never have this issue with regular bluetooth headsets, only with cars. Anyone else have a problem like this?

[Q] Bluetooth Audio Dropping in Car

Happens a few times during my morning commute. I'll be listening to a podcast and using Waze, and the audio from both drops.
Bluetooth is still connected. At this point I can wait it out (usually a minute or two) ... or turn BT off/on again ... both usually resolve the issue.
It's happened since day one - and my previous phone (HTC Inspire 4G, running stock and CM7) never had this problem with my radio.
Anybody else having this problem? Any suggestions on a fix? I know Goog changed the BT stack in 4.2 to improve "reliability" ... but this is driving me crazy.

I've been using my bluetooth regularly in my car (09 TSX) and not once has it dropped/stopped playing music. Whether I'm streaming from Tune-In or just from the Play Music app it always works. In fact it worked for my 3 hours road trip this past weekend without a single issue!
No issues with phone calls either.

I just set up bluetooth in my car yesterday. The audio and call quality is great, but I did have it drop out once. When it dropped out the phone locked up and I had to reboot in recovery. I'm running completely stock and have not rooted.

Try turning off WiFi , mine was cutting out whenever a wireless network became available. I turn off WiFi when I get in my car and have had no issues since

Problem with Bluetooth audio in the car

When I connect the smartphone with the car via Bluetooth, the music is just intermittent suonds. How do I fix this?

I would like to know this too, anyone?

I started having this same issue after the last/first Tmobile update, before it was fine.

Same thing here. The music would either play through the phone's earpiece or sound like a call playing through the Bluetooth speaker. I read YouMail was a cause so I uninstalled and it still happened I force closed the phone app and it worked normally after that. The issue may definitely be from the T-Mobile update tho.

Yeah been having an issue with volume fading after initial connection, drives me nuts since I use the phone for GPS and music streaming. so I use the v30 for bt music and OnePlus for gps

I'm having an issue with the phone trying to automatically connect to a second Bluetooth device and begin playing music on it. This happened tonight while following behind my wife's car.
Every time we stopped at a light it would connect and I would loose audio in my vehicle and play in hers. No way to stop it connecting other than forget the device or turn off all the functions in that device settings.

I have the T-Mobile 6T and I have this same issue.
It seemed like the previous update fixed it, and was broken by the current update. Anyone know if the international rom has the same problem?

I'll be updating this on the weekend. Nothing worse than having the beat drop to have the volume drop...

I feel you, dealt with that for a while until they found a way to convert the phone. anywho hope it fixes your issue.

Bluetooth nightmare
I've been having the same issue since I bought my T-Mobile 6T last year and am pulling out my hair trying to figure out how to fix it. I have a "GTA Car Kit" Bluetooth module installed in my '06 Mazda 3 and I use Android Auto with my phone docked in a CD slot mount to give me hands-free text messaging, navigation and music / audiobooks. My phone is also always connected to my android wear watch, so it's technically connected to two Bluetooth devices at once when I use it.
The problem is that audio playback via Pandora, Google Music and my audiobook app that plays on-device mp3's intermittently stutters or skips. It happens immediately sometimes, other times it will work perfectly for half of my commute and then start stuttering every few seconds until I finally just turn off the music/audiobook completely.
I've tried:
Turning bluetooth on and off
Turning my car radio on and off
Changing the developer mode settings for Bluetooth AVRCP Version, Codec, Sample Rate, Playback quality etc.
Clearing storage/cache for Bluetooth
Switching to the international version ROM for the device
Once I got the Oxygen OS v10 update I really though the problem was fixed, but after a few days of working fine it started skipping again.
Does anyone have any idea what's causing this or other things I can try?
[EDIT] I found one more new thing to try on the OnePlus 6T forums https://forums.oneplus.com/threads/bluetooth-stuttering-solved.1076196/
I'll give this a try and report back
