p3600 A2dp, crappy sound

The quality of music with A2DP is really bad, have much better sound with my qtek s110 with a2dp hack. I have been using the same sony ericsson ds970. Is there anything that can be done about it?

perhaps you can follow the instruction to turn on the stereo, then the sound will be better.

This is my experience to. I had a SE m600i before and the sound was way much better on that device.

The sound clearly suckes with the headset that is packet with the P3600.
The sound on the S100 was far more better.
Lets just hope the ATi chip get's activated on the rom-update, so that the Graphics and Sound get better.

guys, could you please be more specific? what exactly made you unhappy about the sound produced by HTC Trinity?
please define the problem. is it too soft, too loud, lacking bass or higher frequencies, choppy, etc, etc????
P.S. forget about stock standard wired headset supplied with your Trinity. it's bad.

ATI chip?

Guys try using the Hermes Registry Tweaker
I used the hermes registry tweaker to take BT Stereo sound from "Okay" to "Excellent" the tool has five levels of quality as well a tweak to enable true stereo rather than joint stereo.
It worked for me! You can unlock and mount EXTrom too.

It has a desturbing sound on the higher tones and the bas is muffled. I tried the fit4 program and changed to the best quality, it sounded a little bit better but it was hard to hear, beacuse now the music skips even more thnat earlier. You know you ger music for a while, it cuts of for a second and then comes back. Now it does this every 5 seconds.

just tested it here. seems to work. The setting was on LOW on my trinity.
I also tried to turn on the GPS settings, which turned on a nice little menu for configuration of the GPS. Looks promising if this is what we get
does not look like the settings gets any gps functionality to be activated besides the settings.

Excellent
Made a big diference on mine too! Nice to know it worked for you.
Try this to disable joint stereo so you get REAL stereo sound, then you will see the difference.

..now the music skips even more thnat earlier. You know you ger music for a while, it cuts of for a second and then comes back. Now it does this every 5 seconds.

please see this thread for details. There are good chances for this little gem to work on Trinity as well.

you guys might also want to check out the effort made to port the WIDCOMM stack onto the hermes (to replace the microsoft BT stack). the widcomm stack is superioir and the testers so far have indicated that sound on a2dp is great. the hermes and trinity are basically the same... so it might work.

Last time I tried the Widcomm stack the stack started well, but I couldn't see any bluetooth device. The blue-led did not flash either.

Can't find any bluetooth device.

3D surround configuration
On page 78 of Trinity's manual there is an instruction to set the 3D surround configuration at the headset by going to
Start> Settings > Personal > 3D Surround Sound
and enabling surround sound + setting levels.
I simply can't find the "3D surround sound" selection at >Personal tab...
Can someone help me to configure (eventually by using some registry configuration) how to make this command to appear?
Seems to me this could help to improve stereo quality at P3600...

The problem with my new p3600i is that the volume is much too low. With volume control at max setting, I can just hear music in a quiet environment. e.g. an empty room. When there is any background noise, e.g walking along the street, on a train etc, it is almost inaudible. I am mainly listening to classical music, so the dynamic variation is greater than for rock etc., but nevertheless very disappointing.
I am using the supplied headset, but the sound is not loud enough to know what the quality is like.
Are there any setting I haven't found yet? All the talk about changing the ROM sounds like something which might void the warranty
thanks

I have used HTC_UseJointStereff.cab and HTweakC, it seems that the sound changes a little, i don't konw which helps, but they help....
Thank you all.

Trinity A2DP problems - Temporary solution

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!!!

Problem With BT Stereo Headset

After upgrading from WM 2003SE I have not been able to use my BT stereo headsets. I have both a Motorola S9 and a Jensen WBT212. The music from audio manager or WMP will start but then it will become choppy as if the connection is going on and off every second. Didn't have this issue with WM 2003SE. When used as a handsfree headset there is no issue. I also noticed the elapsed time of the song in progress is also erratic. This happens to both media players. When the BT stereo headsets are not used both players play normally. Anyone else having this issue? Any ideas or resolution would be greatly appreciated.
Device : Siemens SX66(WM6)
ROM Version : 5.60.00 WWE
ROM Date : 03/02/05
Radio Version : 1.15.00
Protocol Version : 1337.45

I finally got the bluetooth headset to work by installing the Helmi BT CAB for WM5 I found in the WM% forum. It is kind of strange now that it seems l;ike there are two BT connection managers but I can now get the headsets to coneect properly and the media players seem to be working properly too.

Hi I have that weird skipping problem with my HT 820 motorola stereo BT It's not really bad but it shouldn't skip I think. could you send my a link to that cab? any help appreciated.
Thanks Gyurma

I got my new BT headphones yesterday. Charged them all day. I did the pairing thing last night. They worked great. Fantastic. The audio was crisp and clear. I was able to answer the phone with them, and again over the phone the audio was great on both ends. But it's like that poem about the girl with the curl. When they're good, they're very, very good. But when they're bad, they're horrid.
I've spent the entire day fighting with the BT. It seems that I can use the headphones only right after I pair them to the device. If I shut them down or turn off BT, when I go to restart, I get the choppiness that's so bad you can't even understand what song is playing. Resetting doesn't fix it. If I uninstall the headphones, turn off BT, and then do a hard reset and reinstall the headphones, I can use them again and everything is perfect. Until I turn them off, and then it starts all over again.
What is causing this?
I know I could just install the Broadcom BT. In fact, I did today. Twice. The problem with that is that I can only get it to recognize the headphones as a high quality audio device, not a headset phone device as well. I can install it as both, but they don't play nice together when I do, and if I install it only as the high quality audio, I can't answer the phone with it. (And yest, I did install all the patches and addons I found throughout that thread.)
Also, the Broadcom audio quality isn't as good as what I'm getting with the MS. Almost like the difference between an mp3 encoded at 96kbps, rather than a better quality.
I've tried the A2DPAudioFix. No help there that I could find.
Am I missing something?
Is it really a choice between crappy audio quality and no phone headset functions and having to hard reset my device over and over?

Same exact problem
Just upgraded the radio today to 1.15 and rom to WM6 last week - Bluetooth stereo headphones work ok for phone but not for music. Please can someone posts links as to where I need to look for various cabs - I've tried searching the forum but am not having much luck. Just happened to stumble on this thread.
Michelle

Stereo bluetooth works now
Well - my dh is sick of me working on this - but I know how BT stereo headphones that work w/ audio and the phone.
I am not even sure what I did other than install every cab I found and I'm sorry I don't have links-
RestartRadio.exe
BroadcomCorp_BT1.0.0.3900.cab
RestartRadio.exe
(still had problem w/ scratchy / stop / start)
then ran
ba_oem_audiogw.cab
and
BroadcomCorp_BTUpdatefor1.0.0.3500.cab
but I don't exactly the order of the last two - I am not even sure I ran the audiogw.cab - anyway, it was like magic - stereo sound minus static and skipping.
This is after flashing to wm6 and flashing the radio to 1.15 - and there was something else I tried - oh, I did change the registry to 64 from 128 I believe - the SD card entry.
Anyway, it's been a long day - now I'm off to figure out how to change the 72M B free in Program to give some to storage which only has 5.48 free.
Michelle

Mgrunk- Which SD card entry did you change? Could you kindly check to see what version of BT you are now on? Start/Settings/Connections/Bluetooth should get you to the version. I have mine working like I described earlier using the HELMI WM5 Broadcomm 1.7 cab, however still have periodic static and skipping. I am curious because my BT headsets worked well with WM2003SE and BroadcomCorp_BT1.0.0.3900.cab. Thanks in advance for any info.

In regards to the version - now I have to BT icons on the Connections page - the About on the second icon says PE "Version 1.0.0 Build 3900"
But last night I deleted AudioManager and then had the horrible BT stereo headphone problems - I also noted while WMP was playing, it sucked the available program memory down to 5M - didn't matter what I started w/
I reinstalled AudioManager - no luck w/ BT, renistalled all the BT cabs

I have to go into CommManager and uncheck handset and headphones, click save, go back and click them back on and click save and then start audiomanager up and play music. But, I found that even w/ that I had to repeat the whole uncheck the services and then recheck them - somehow it's different than turning BT off and then on (that didn't work at all)
*** hey this morning the BT stereo headphones worked fine w/ AudioManager - didn't have to turn anything on or off - once in a while there's a short pause in sound but otherwise it sounds fine.
*** for no reason, BT stereo headphones are back to non-functioning - tried soft reset, reinstall cabs, etc. - no decent sound out of them - of course they work great for BT phone. Any suggestions?
I was a programmer in my former life (before 8 kids) and I design websites, but I was totally frustrated w/ the BT issue - so I'm not being methodical and I didn't really find a definite thread that said do 1, 2, 3 - so I've thrown every cab I can find onto my system.
I'm sure this doesn't help - it's very scattered and unorganized.

meanwhile found the Helmi BT 1.7 but I am getting a insufficient driver memory available. I have to preform a soft-reset which I did but didn't help. Whats is the solution?

Give up
ok, it's back to not working - I'm going to return the stereo BT headphones and wait for a new answer - maybe it's the headphones.
But, in regards to the about screen - I had 2 BT icons on the Connection page and the 2nd one had an about page - I hard reset today and it's gone.

Mgrunk- I hard reset a couple of days ago as well just trying to cleanup because having two BT connection managers was bothering me. I have gotten the MS stack to work better by doing the SD card registry edit you suggested and another one at HKLM\software\microsoft\bluetooth\a2dp\settings\bitpool and setting it to 25 then settling to 23. It was at 48 when I started. The lower the number slows down the data transmission rate and reduces the choppiness. The lower the lower the sound quality as well so you will need to adjust on your own. Start with 25 then work your way down. What headset were you using?

Well that worked sort of
I changed those 2 registery values - I had to take the bitrate back to 21 - the sound has really degraded - but the music plays - who knows if it will work tomorrow.
Oh, and I have a set of Spider BT stereo headphones - the people I've called said the sound is fine so the mike works ok and the sound is great for the phone.
They're behind the neck, over the ear as opposed to earbuds but I didn't want wires. The ones I really wanted were $129 - earbuds behind the neck.

I've been able to keep my BT headphones working by deleting the entry and forcing them into pairing mode and re-pairing them whenever they get choppy. If I'm careful about how I shut them down and restart them (shut off music, wait until I hear the headphones stop transmitting sound, shut off headphones, shut down BT -> start music, start BT, start headphones) I can use them several times before I have to re-pair them.
But it still seems very weird to have to go through all this crap to use them. If I deviate from that shutdown and restart pattern, I have to re-pair them to get them working properly again. If I do a soft reset, I have to re-pair. It can't be the headphones. They work great with other BT applications.
They do work fantastic when they're working though.

so, now I'm off to convert some of my music to mp3 - and then I'm going to try some different players - AudioManager has the same issues w/ wma music as WM10 player - having the bit rate down to 21 really makes for some static in the music.
Update: didn't work - low rate mp3's w/ MortPlayer had same issue

A2DP skip : any solution ?

I am trying Touch HD with a Jabra 620s, A2DP (stereo headset profile), but I suffer occasional music skips.
I have read numerous thread about this problem, and habitual registery fixes like Priority256 etc.. doesnot seems to work with Touch HD.
With Bitpool=30 I have no skip, but sound is awful.
With Bitpool=40 I begin to skip. JOINEDSTEREO=1 helps a little.
I have not tried all Bitpool values below 40 (painful, softreset etc..) but Bitpool=40 is minimum quality IMO.
I tweaked Priority256 (/HKLM/Drivers/BuiltIn/BtA2dpSnd) down to 1, with not much improvement.
I noticed also turning Wifi off helps, but it is no sufficient.
Does anyone of you use A2DP ? Do you have problems ? Thanks for your help.

i use it with the Sony Ericsson DS980 and i dont have any problems at all.. the only thing i notice is that the screen turns on every time i change the song.. any way to get rid of that? want to save battery lol.. ..

I get skips too. Haven't figured a solution yet.

I'm using Moto S9 stereo BT headset, I have the same problem......
And I noticed, when I start play music, and press the powerbutton make the HD enter the blackscreen mode, the quality is good, and music play very smooth, but if I press powerbutton again make the HD back to normal status, and screen on, big stutter occured, and after some seconds BT lost connect with HD......

It's a little outdated, however have you used Sleuth's A2DP fix?

i always got skips with a jabrabt620s and a trinity...well you can minimize it - but never get totally rid of the problem....this is an A2DP limitation, sensitive to EMI like wifi etc.
My suggestion: go to wires...

Skipping?
I've been using a Votager 855 A2DP headset for 6 or so months with Pocket player. It's an excellent application, complete with A2DP compliant equalizer.
I listen to head banging music, but it never skips...but maybe it does and I just don't notice between the bangs.
In another forum several months ago a person or two took up my suggestion on the PP app, and had good results with a stereo BT headset.

I've seen it, but not installed it for two reasons :
1) It isn't validated for WM6 nor for Touch HD
2) It seems to eat CPU time too much, according to certain posts
Thanks for the tips anyways. If someone more daring than me installs it on Touch HD, keeps up informed.

A lot of people have problems with A2DP, but a lot too have none. I'm pretty sure problem comes from poor BT stack, not A2DP technology itself or BT broadcast / EMI problems. I've almost the same skipping rate with my headset 30cm from my HD, than 5 or 8m from my HD.
Your suggestion is wise, but I'm eager to make my Christmas present functionnal..

I've just downloaded it and tryied it. For now, no skip at all !!! (with BitPool=42) This application seems to be very optimized for A2DP.
I keep you informed in this thread if this resolves my issue. I want to increase Bitpool to 50 or more to have optimal quality (I listen classical), and I hope PP will handle this datarate.
Thanks for this excellent advice audscott.

I also have had no problems using the HBH-DS980 except that I too can't get it to stay in 'standby mode'.
I started a thread on this exact same issue, but have had no joy up until now.

dear all,
i remember searching up for ad2p anti-skip quite a few months back.
my conclusion was the following settings:
jointstereo -> turn on
samplerate -> 48000
remove all bitrate settings
then all should be well.
The previous settings that involves bitrate, priorit256 are meant for wm5 devices.
in wm6.1, most of these are redundant. in my case, the above settings works perfectly on my itech blueband pro. ad2p and avcrp works well with the default player or with wmp.

Where can one find these settings? I have looked high and low!
***Doh! Found them... HD Tweak is my friend!***

I also have iTech BlueWhatEver and it works better, but still ones a few minutes sound skips
Also how to prevent phone from waking up from standby when I press pause/ff/rew button? Because it's ****ing annoying, I have to manually turn phone back off, so avcrp is totally useless if I have to touch the phone.

I suggest you lower the bitrate to 44100. 48k is useless since your mp3 are in 44.1kHz and you will save some CPU, bandwith
Jointstereo = 0 is prefered for quality purposes.
Then the bitpool ... this is where it gets tricky because every headset have their own limitations.
When i use it with my sony ericsson HBH-IS800 I can go up to 48.
If I use another device I need to lower it to 40.
The "CPU" of you headset needs to be taken into account.
The touch HD have no difficulties encoding SBC in realtime in high bitrate, the issue comes from the headset itself not able to decode SBC fast enough according to the bitpool you chose.
So there's nothing you can do except trying another BT Stack (that can have better SBC encoding algorithm) or changing you A2DP headset.

A2DP sound quality issue with Galaxy S 2

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
there is an mp3 sample of the problem in the first page

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...
http://forum.xda-developers.com/showthread.php?t=1117769
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...
http://forum.xda-developers.com/showthread.php?p=14944891#post14944891

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?
