Well, I was unsure if I should post this under one of the old posts, but I decided to start it as a new clean post...
Many are having problem with "hissing" noise, joint-stereo and low bitrate(or bitpool). For my sake, I've tried "fit4cat - Hermes Tweaker", "Sleuth255 A2DP fix" and several other methods, but without beeing able to get the soundquality I want from my headset.
Now, this is what worked for me after tweaking around with the registry a while, and endless pairing sessions
Download a registry editor(I use PHM, http://www.phm.lu/Products/PocketPC/RegEdit/ <- Download the PocketPC 2002/2003 ARM/PXA)
1: Turn off bluethooth on the Trinity
2: Unpair the Trinity with the headset(Delete the headset from the list!)
3: Change the following registry settings:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\A2 DP\Settings
MaxSupportedBitPool=80
MinSupportedBitPool=40 (or more if you want)
(if these arn't there, add them!)
And DELETE:
UseJointStereo = 0/1 (depending on whatever you have put there before)
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\WaveDev]
Priority256=149
(let the rest be as it is)
4: Reboot
5: Now, DO NOT use the headset for direct pairing!(since you've already added your phone to the headset, pressing a button on it will useually pair it back with the Trinity) <- This seems to be the function that triggers the sound-problem...
Instead, set the headset in visible mode, and use the trinity to pair(search for new devices), when you find the headset and pair it, you will hear the pairing-sound from the trinity-speaker, and NOT the headset.
Now you can enjoy high quality stereo sound without any disturbance
But, the problem comes when you turn off your Trinity, or the headset. If you try to connect the headset and the phone by using the connectbutton/playbutton on the headset, it will pair, but this time you will hear the pairing sound in the headset, and then you have all your problems back... So then you have to turn of bluethooth, delete the headset from the trinity, and add it back once again by turing the headset in visible mode again.
So the solution to this, is to go to the device list on the trinity after you have lost connection with the headset(this is if you have turned of the trinity or the headset), and hold the stylus on it and choose "Use as wirelss stereo" and "use as handsfree"...
Thanks to all of you guys here who have posted solutions to the A2DP problems And if anyone have suggestions to other values that are better fit then the onces I've supplied, share them with us
And if all of this have been posted in another thread that I've missed out, the moderators are free to delete this one
Good grief, I can only imagine how many times you had to pair the headset before you noticed what was going on LOL, hope you didn't turn blue in the face
I imagine a ROM update could fix this problem.

Hehe! The thing that made me going was that I was able to get perfect sound once or twice, and since I made it work those few times I just had to find out what I actually did that made this work (And paying 175$ for the headset also keept me fueled for a while ) hehe!
I think I've used about 5-6 hours total these two days sitting pairing, adjusting settings, rebooting(ARGH!), untill I found out that the problem actually occurs when you use the headset to pair instead of the trinity
I don't understand what is it with bluetooth stereo:
quality is not good enough to listen to music 64 kbps... no bass, no medium, nothing just a hiss.
and plus you get 80% cpu (with a 400Mhz...), just to encode this crappy 64 kbps.
Yes exactly for all people having so many skipping problems check your cpu with taskmgr.
So you cannot play video with A2DP unless you have 1Ghz!!! good for battery life.
If you like music you want good earbuds. There's none with A2DP.
So what's the point again apart from having to charge one more device?

1: Well, I'm not sure on the bluetooth 2.0 specs, so If there is a spec limit on 64kbps, then this is new to me.
2: And the skippingproblem is not just connected to the CPU-usage.. But if you have some info on this issue, then please; do share it with us.
3: A2DP headset with minijack is available many places, even HTC has one. And if you take a look at DS970, you will see that it's the same as Sony MDR-series.
4: And well, the CPU usage is a issue, but that is the only part that I agree with you on..(but let us be frank, I've bought a pair of A2DP headset, so I do smell a bit "conflict of interests" here...)
And to the bottom line, I've bought the Trinity because it's one hell of a gadget, and so is bluetooth stereo So if anyone want to shoot me for that, well hell yeah, go ahead
Edit: And FYI meroupow: I do feel you are a bit rude in the way you wrote that response, or at least a bit arrogant when you post a comment like that. Trying to mock people who have bought A2DP headsets and are tweaking and fixing issues to make them work correct(this also goes for GPS on the phone, black coating comming off, improving camera quality, getting the ATI ImageOn to work correctly... etc) . And I must honestly say that yes, you do have some points there, but you should be able to present your views in a much more polite way...
Sound better but discontinuou. Impossible ear music. The sound goes on and off continuously. Why?. How can I do?
I am sorry if you felt I was being rude.
That was not my point and It was probably the wrong place to say what I said.
It is just that just like you I bought this A2DP stuff with my Wizard.
Just like you I tweaked it as much as I could and managed to get it work.
The problem is when it comes to sound quality is important and just working is not enough.
When you show your happiness because it's finally working, people think you are happy because it's good and they are buying it. And get disappointed too.
I just wanted to warn people on the fact that it's not working to watch movies because of cpu and that a 5$ earbud will have far superior sound quality.
It's just a toy and by no way a mature technology.
I've got a CB2530, hard to pair and I still don't know what do I do for the pairing to be successful, but I do manage to pair it after a few attempts, on the registry I just disable jointstereo, set the MaxSupportedBitPool to 320 and the quality is quite nice and with minimal skipping. High cpu usage of course, but if I set the MaxSupportedBitPool to 80 the quality is quite crappy and the device gets equally sluggish(gets worse when you touch on the screen, as K-Rally does even with the new ROM).
As for the pairing, I still haven't confirmed, but I think the registry setting that enables the bluesnarf option on BTCrawler has something to do with it(the bluetooth ISC mode thing), because right after setting it I managed to pair the headset right away, the thing is, I was also successful in other occasions when I hadn't set that reg. option.
Hearing the pairing sound from the trinity or headset doesn't indicate anything on my case, and I think I've already tried these reg settings you mention, but I'll try them again as soon as I get home to see if there's any difference and post the results.

Install the Widcomm BT stack. With that, you won't have complaints - neither have I.

Does anyone know what is changed when you DO pair with the button on the headphones? With some models, you MUST do it because, otherwise, the music will be muted after about a second (see http://forum.xda-developers.com/showthread.php?t=282008 for more info).
I've searched around in the Registry for changes, without any success. It's possible we could directly edit the headphone connection-dependent parameters set AFTER the headphone's initiating the connection to avoid sound problems. If we knew where they're stored, that is.

BTW: is it the profile and software on the phones/PDAs that arn't handling it, or is it the standard itself that sucks? (or in other words, should I keep my headset for later usage or return it to the store)
I use Plantronics 590a and the skipping problem appears very rarely, mainly when I use volume/track buttons on headset. However, yesterday I also connected the headset to a normal stereo (via the 3.5mm adapter) and noticed the same occasional skipping. So in my opinion the skipping issue problem might be from headset, not Trinity.
I also tried a Nokia stereo bluetooth headset and noticed serious skipping problems - unusable.
PS: there is indeed a skipping problem if I open/close other applications while listening to music. It looks like the processor is very busy - system very slow etc.
PPS: any suggestions for a player that has equalizer? WMP doesn't and the sound is not that great (especially when compared to my old SE P900 which had an excellent player - best I've heard so far... )

Stereo BT experience is very positive
Hi all,
As always, someone has to have a different view of the issue. I got my trinity a couple of weeks ago and went and bought a Plantronics Pulsar 280 stereo headset. Mostly because of the stereo jack. I have not updated trinity nor have I applied any fixes, just paired right out of the box, as always from trinity BT manager. It really sounds great, particularlly the base is fantastic because of the earbud design. Even you may choose the actual headset of your dreams by using the standard 2.5mm jack. I have owned a "no brand" headset (still do) but it is not BT 2.0 and I think it makes a difference. The plantronics does not skip and it sounds great. Most of my MP3 is 128k and above so no limits with that. I have not checked my registry settings as they are default rom image set. I am using ROM 1.15.412.2 and Radio 1.20.00.11 (my trinity only speaks spanish for now, hope to change that soon).
Point being that the software and quality of the headphones makes all the difference, don't be so quick to blame trinity, just a piece of my mind. Keep it up guys!!!

Ok, I'm looking for some way to route the audio of my Magic to a mono BT headset. I have been searching the threads and Google for days now and unless I'm blind (come to think of it I've been called this before) I can't find any app for this purpose. I had a program called BT Audio for my WM phone that worked like a charm. Anyone got any ideas or up for the challenge to making an app let me know?
Android 1.5 introduced A2DP support, so all you should need to do is pair the device and fire up the music app (might be a couple more settings in between, but AFAIK it's a simple pairing job). So I'm wondering if your headset doesn't support A2DP and that WinMo app was channeling audio through the regular headset profile.

Your right my headset doesn't support A2DP (It's cheep ). I know it is possible though, cause sometimes when I am using an app or game with audio and someone calls in I hear the audio through the BT headset for a sec before the phone connects.
WinMo had a few different apps for this so I'm surprised that I haven't been able to find anything for android yet. I didn't think it would be that hard to do.
It could be that its built in to the ROM that I have and I just haven't found the settings for it yet. I'm using the My Hero ROM. If anyone knows Let me know.
Hi!
Once you pair your device (on my Cyan ROM anyway...) you can go into the BT settings, long select the device you just paired with, choose options and if it supports X feature on the BT profile (in this case, audio) then there will be a check box that you can click to enable that function/feature.
Other than that, you might have some luck searching the Market for an app similar to BT Audio. I used to have a Shadow and I know exactly what app you are talking about, all in all though I was less than impressed with the meager selection of apps I had available compared to what I have now; and definitely even the out-of-box experience is light years ahead of any WM experience. What I ended up doing instead was just grabbed a new Stereo BT headset and problem was solved There was one on http://www.woot.com a little while ago that I'm loving (LG BT250 I think?).
Good luck!

I wish I could . I didn't mean the one I have was cheap in the way of money cause it cost me $80. Cheap in that it was the cheapest of the headsets that I could get with voice recognition built in as I work and drive around a lot of noise. I didn't want to pay the $130 for the good one.
I wonder if there is anyone with the right skills out there that can write a app like this. hint hint.
I do appreciate all the work that goes into making these cool app that I use every day so if nothing shows up, I guess I'll have to live without.
Thanks guys!

Dunno, I think they just want to advertise the site in their sig...
I have a stereo Bluetooth headset (Plantronics 855) that works great with the Droid; however, there are times when I want to sent A2DP to my Jawbone Prime, which is not A2DP compatible. The profile only shows phone audio when selecting the device in the Android BT manager. What needs to happen to transmit full audio to a non-A2DP headset is enabling SCO (Synchronous Connection-Oriented) connection. I have searched everywhere I cannot find a software gateway that enables this feature in the Droid. There is an app in the market called Sound Route Switcher that claims to enable this but then blames Android for is application not working with Bluetooth.
I will keep looking and post anything that I find but I am stumped to this point.
Thanks dbigdawg
There's a little Greek in there for me, but I appreciate the effort and I'm sure many others will too. Look forward to what you can find.
Hate to bring back an OLD thread, but has there been a solution found?
Last I looked was back in April.........................Nothing
But like I said before I have been known to be blind to anything past the end of my nose!
I really miss being able to listen to music all day and not have on headphones.
Thanks for the reply bud. Maybe with some luck I can see if I can find that old file I had that was supposed to work, but didn't on 1.5. Now that I use 2.1, it might be a different situation. If I can locate it I'll post it here.
Hi, there is a new app named "Super BT Mono" which could route audio to bluetooth mono earpiece. It might be what you are looking for.
Thanks
Thanks for the info. That Super BT Mono did the trick for me.
is it just me??
there aren't that many reports of this issue on the net. it was briefly mentioned on one of the reviews and that was it.
anyway, on higher bitrate mp3 playback, bluetooth headset audio stutters and skips a lot, even if the device is held very very close.
wifi was not running, 3g data was not on.
if you guys think the issue I posted on google Android's bug site is relevant, then please vote.

whats the x10 like by the way...it looks really nice but someone somewhere said SE's skin is slow?
how much battery life do you get out of it?
I do have trouble using just a plain headset. I only get about 30cm range before the audio begin to stutter.
I've tried with two different Sony Ericsson headsets (HBH-PV710, HBH-610a) and a TomTom Go930.
Is it a software issue or hardware related? Repair?

am guessing it's hardware...
but perhaps it can still be helped by modifications in software
basically im still getting the same issues with a custom ROM
Got the phone replaced with a brand new, still the same problem.
Audio in headset is really bad, but in the other end they can hear me loud and clear.
Could it be poor output power from the Bluetooth transmitter in the phone,
while reception is good?
I've restored it to factory settings, and had WiFi disabled.
I've got the same problems on my Legend.
Both A2D2-profile and standard audio for talking.
No more than 80-90 cm before the static and noice occurs.
My colleague here at the mobile-store had the same problems on Hero, and now on his currently X10..
So to me this seems as an Android problem overall, but I can't tell for sure..
My Legend is my first Android handset, and I like it..
I only wish these blutoothproblems hadn't been here.. Should have been just the same as on my beloved Sony Ericsson handsets..
Got a new headset a Nokia BH-602 and the audio is a lot better, not perfect but at least I can hear every word said.
It's quite strange that SE HBH-PV710 and HBH-610a including TomTom Go930 just didn't work.
I'm just curious what qualification Android or Bluez did meet to certify for the Bluetooth standard.
Sorry to bump an old thread...
But just wanted to add I have the exact same issue, the bluetooth range is not very far at all, however it is a lot better then 30-60cm.. i'm able to go for about 2-4 meters with line of sight.
So i guess its usable as long as the phone is in my pocket which is fine.. just wish it was a little better like my previous phones where I can just leave it charging and walk around the house.
Bluetooth support is pretty atrocious on this HTC Legend.
Never had any problems streaming audio or using any of my previous devices with my car stereo for handsfree.
But this Legend is pants! - It won't work with Bluetooth Audio streaming at all - I just get static and some wierd clicking noises (using 2.03 latest official ROM) and handsfree connects ok - but then drops half way through a call causing me to lose my call at the time.
Any resolves for these bluetooth woes?
thanks in advance.
PS - Using it with my Pioneer FH-P80BT
I use my Legend with a pair of Sennheiser MM400 headphones. I have no stutter with bluetooth stereo (except minor cuts when browsing some intensive websites or typing fast in landscape mode). My headset works well even with the phone in my pocket (although it skips momentarily if I turn my head right or if my hand touches the bluetooth transmitter near the camera lens).
Perhaps some of the reported problems are caused by some background process using CPU cycles with high priority?
Incidentally, I highly recommend these headphones - bluetooth playback is of identical quality to wired playback. I don't know how Sennhesier have acomplished this feat but every other brand of bluetooth headphones I have used before have had intolerable reproduction of high frequency sounds.
I am having this problem as well...streaming music from my T-Mobile Vibrant to my radio via bluetooth. The radio is bluetooth 2.1 compatible and the Vibrant is supposedly Bluetooth 3.0.
I used to have a Mytouch 3G running Android 1.6 and I do not remember having this problem.
Same problem here !
am using Legend, and "Jwin Stereo bluetooth" headphones that needs "A2DP" to work, and its working clear but there is some silly cuts while listening mp3's and its disturbing me, i cant ignore these cuts coz are alot !
Please tell us if there is any way to solve it ...
Thanks..
Maybe this should be in Accessories, but it seems more like a general question.
I'm in the market for a bluetooth device, but being that I use my phone as a music player, I had a question.
When hooked to bluetooth, and my car stereo, is there a way to separate calls so they are routed to just the BT, but when the call ends, the music will play through the 3.5mm jack?
I'm probably not making any sense, but I hope you get the gist of my question.
Thank all!
Yeah I think its possible
I remember I had a pair of blackxbeats or something like that with my hero and when I paired it, I remember that it linked to music and calls seperately
I think you can disable the musiclink when you pairand when you're done with the car dock or whatever you just tap it and it'll take the music too.
I might buy another bluetooth because I forgot how convenient it was lol

It really depends on the BT device you get, I think. I had a Moto stereo one that allowed you to separate those functions in the phone's settings, but the Sony one I just got (model MW600) has its AVRCP functions crippled if you don't enable it for both phone and audio. This is one of the reasons I like the Blackberry Stereo Gateway, because it's designed only for audio, just a dumb but well-designed audio BT receiver that works simply and well for the car and almost never needs to be touched.
The guys at my local electronics store say Plantronics because of voice clarity.

I was able to apply this fix to legendary rom with samurai kernal el30 modem and all is working perfect.
To be exact went thru asound.conf found headphone_in call section change 4 to 5 for bluetooth restart and everythings works perfect when call comes in radio pauses and come back when call is complete. everything else like voice commands thru bluetooth dont get routed they still come thru speaker thats OK for now.
Hi guys
i read xda so much, but i don't write as well
i have a big issue with my galaxy s 2
i use a bt car stereo, with a2dp and avrcp support
i used to stream all my music collection from my iphone4
now i got my sgs2 and i love it... but
the audio stream looks "limited"
it seems a bandwidth issue, or i don't know a quality issue
with iphone4 i streamed at full quality, now the sgs2 sounds a lot worst
other than that, i have to disable wifi because if on, the music is choppy and skips a lot
with wifi off, the stream goes well, but it sound bad...
sorry for my not so perfect english... i hope there is a way to improve sound quality because i "live" with a2dp on in my car...
That's strange. My a2dp stream actually sound better from sgs2 than it does from my ipod touch 2nd gen, iphone or my computer (bluez).
Receiver is a belkin stereo a2dp receiver.
Are you sure that it's not in handsfree mode? Long press the a2dp device in bluetooth settings and there should be an option to select it to be a media device, make sure it's checked.
thanks for the reply gvoima, no it's in media device mode
i think the problem is the bitpool
i've got the same problem of this guy: http://forum.xda-developers.com/showthread.php?t=708685

I got a belkin stereo receiver as well, but it sounds bad and choppy, just like the topic starter described. Though still compressed (this is a known issue for A2DP due to bandwidth limitations) songs sounds much better from my Nokia E52 work phone.

The "but my (insert phone) worked better" isn't really valid. For as many people who make that statement there are an equal number who are shocked that the SGS2 works where other phones haven't. This is kind of like the Wi-Fi issue. When two pieces of equipment don't interact well you can't just blame one of them.
In my car and on my Yamaha YSP-4000 the SGS2's Bluetooth works better than any phone I've used. That includes the HD2, G2, and G2X. The sound is much more defined and headset controls (random and repeat) show available for the first time. The SGS2 also feeds track info to the car which none of the others did.
Bluetooth connections and sound quality are always a big YMMV.
My Sony MW600 sound great, I use to have a Motorola Defy , and it use to have an "Enhanced Stereo" option in the blue-tooth menu, the Samsung S2 does not have this option.
@BarryH,
Oh I know, I not blaming the SGS2. I only think the SGS2 out sound to it's output module which is somehow less suitable for the kind of compression, maybe set by the Belkin module. Actually I'm currious if there would be ways to change the way the SGS2 sends sound signals via A2DP

LG's implementation of Bluetooth drove G2X owners crazy. Check out this thread from the G2X forum...

Maybe it will help. The only other solution for the G2X was installing an AOSP ROM.
Well, I tried it (Bluetooth Fix Repair), but off-course that tool is for a problem the SGS2 does not have.
From the tinkering I've done now I know.
- Having MusicFX installed does not make a difference
- Video players running ffmpeg codec do also not make much difference in sound quality
- The -type- of file does make a difference, i.e. low bitrate files play better
This makes me think, is there a music program which can resample/recode music before playing. I'd rather have software do that than A2DP do it badly, or is mono output (other than all the tools enabling playback on mono headsets which is for pre-A2DP headsets and thus something else) possible?
Edit /system/etc/bluetooth/audio.conf
Uncomment "Master" option and set it to "True".
Uncomment "MaxConnections" and set it to 3.
Most Android devices have this file configured poorly by default, those 2 settings should help though.
I'd suggest also enabling HFP and AutoConnect.
Great! That definitly reduced creaking/noises and even the occasional stuttering music!
Since you seem to know your stuff, would there be a way to send a mono signal to (only) the A2DP stack and would this decrease the 'tin can' effect? I'd rather have better upper tones than stereo.

Thanks for the suggestions...going to try this and see if the sound quality improves in my car stereo.
Till now the best A2dp sound quality was on my Nexus S, but that was with the help of custom rom development and vodoo sound. Worst was the g2x.

Ok guys, I think I might have... accidentily... run into a phenonemon.
I tested my phone on a Creative D100 wireless speaker it it went great, no tin can sound, no hickups.
This proved to me that there had to be something wrong. Now when I was posting here earlier I was listening a lot to music and at a certain moment I thought... wait I'm not hearing a tin-can sound anymore. However, later on while testing I heard it again so I thought I imagined it.
Powering off the phone and powering on again I was able to create this again. No tin can sound... however a lot of hickups (as if a lot of data had to be sent and it didn't quite fit). I made a call to my work phone (sound on the handset) to test and then the tin can sound was there again, no hick ups anymore though. Strangely enough a haven't been able to replicate the 'no tin can sound but hickup situation' though by powering off and on again. Tried after playing on the Belkin on the D100 again and no problems at all, great sound and no hickups whatsoever.
It appears to be a bigger issue with android connected to the bitpool setting the bluetooth receiver desires...

Let's hope the upcoming Cynogen can fix this issue.
I too felt that the A2DP sound quality on the Nokia BH103 is crap as compared to my Nokia 5800 (sounded even better than stock wired headset). It also uses a lot more battery, I find mediaserver using a lot of battery.
How do we escalate this to Samsung?
