[Q] Best WP7 version for Bluetooth A2DP? - HD2 Windows Phone 7 Q&A, Help & Troubleshooting an

I have a stereo bluetooth headset (LG Tone) that I have been using with my HTC HD2. When used with Android, I get pretty good sound quality. However, in WP7 (I have tried two 7.8 ROMs) I get horrible sound quality with a hissing staticky noise. Anyone else have this problem and know a solution or a WP7 ROM that doesn't have this problem?
Thanks

check how many fast is your SD card (with WP Bench)... if lower than 6 MB/s change Sd card...
but unfortunately if you want good and no problems with A2DP you must buy original WP7 device... HD2 device not originally supported by WP7 and all drivers and settings developers make by own and still BT functions not working very well on HD2 with WP7

Ansar Rom works for BT A2DP.

That it does, and it's a fantastic ROM, but there's still absolute horrible sound quality through my bluetooth headset. It's a real pity, because Windows Phone is so brilliant otherwise, and it sucks to have to leave it over such a minor quibble...

Universal's A2DP Quality

Hi,
maybe someone can give me some info.
Have a T-Mobile Germany MDA Pro with the newest Stock ROM supporting A2DP.
Have board a brand new Plantronics Pulsar 590A Headset. It works, but the quality of the sound is very very bad with my Universal. I have also tryed the smal A2DP Sender, that comes packed with the Plantronics device and the quality is 100 times better. What is the problem? Can I adjust the bitrate of A2DP transfer in wm 5.0 registry?
The sound is a little much deep and on mid to hig frequencies, i hear a high frequencie noise.
Does anyone else has this problem?
This is not a problem of the receiving device.
Thanks for any help on this :`)
No Ideas?
Please Help!
I have the Qtek WWE ROM on my Qtek (latest official version). I use a Jabra bt620s, and i have no problems with it.
Maybe it's some obstruction of the signal? Do you encounter the problem when the Qtek is in clear view of the headset at a meter away?
I have the Motorola HT820, and finally got round to installing the Qtek WWE ROM today. Connects fine, I can walk into another room from the Uni and have no problems; But -
I also get a high pitched noise, particularly on music with lots of treble. It can be controlled up to a point by tweaking the graphic equaliser, but it is still annoying.
When using the HT820s linked to my Bluetooth PC and laptop, they sound superb - so it is a problem with the universal.
Thanks so far, i start hating my Universal ....
I think, there can be 3 reasons for that.
The Windows Mobile A2DP Software encoder, if it is software encoded.
The Bluetooth Chip, if it is HW encoded in Bluetooth.
The Radio ROM or Chip, if it is encoded on the Radio Processor.
I am not so deep in the Universal Technologie, but i know, that the sound was very clear on Blue Angel using the broadcom stack. So I think, it is M$ Bluetooth that makes the problem, but i am not realy sure.
... or is there anyone how don't has this kind of problem?
Hi,
I personally have never had that problem (which I interperate as "some form of noise" when listening to music over A2DP) you guys mention here, neither with my Motorola HT820's or i-Tech BluePRO's.
Only problems I have had with A2DP and my Universal is;
1. Pause/Resume button not working always in Windows Media Player (works fine in latest version of PocketMusic though)
2. Not automatic reconnect of A2DP when I turn headset on (only prob with the i-Tech's, Motorola's seems to work fine)
3. Occational drop/loss of sound for a second or two (have this under control now, only an issue for me now, when there is to much obstructions between Universal and my i-Tech headset)

This is a general Universal Problem. Maybe Radio Interference, maybe missing some CPU power.
The noisy and unclean sound can be a ROM Version Problem, if you don't have that. I have tryed also with a Linux Computer as A2DP SINK Client, and the sound is same bad.
That's my ROM Version Info:
ROM-Version: 1.30.113 GER

Try downloading the latest PocketMusic version (if free for 30 days I think...so you'll be in heaven for 30 days at least), there it works perfect. ...it was enough for me to "cough up" the money to buy it!
And yes it seems to be every second time, and then one has to press button on Universal/Media Player once...bloody irritating...when the Universal is in the bag or something.

Yepp, I have exactly same behaviour (handsfree no prob, while A2DP needs manual reconnect with iTech's...but with the Motorola HT820's I belive it was automatic though)

For me I am pretty sure it is pure radio problem now (have tested with an app called SuperTask, and A2DP takes approx 20% CPU, and my JasJar now used a total of 40-45% CPU when I listen to music over A2DP with PocketMusic). I only have this problem when I have the JasJar in my pant pockets, are in an area I know there is a lot of interference+have some obstructions. Except from that it is fine now.
You can see this post on my "socalled test" (it was just a simple test, but it seems to give a good indication at least) of A2DP's effect on CPU here;

I have no clue...do you have a Universal (I would guess so from that you post it here )...if so the HW is identical...so then...yes it should be the SW/ROM...since you actually have tried with another "headset" (your Linux computer). But I am sorry, that I am not much of contribution...if nothing else...I agree with your logic here!
BTW my ROM version++ is stated in the A2DP-test post I linked to above (don't remember the numbers...but I have the "latest QTEK WWE" ROM).
Thanks for your comments.
Maybe it's the T-Mobile Germany ROM that is the Problem. Have allready called the technical support at T-Mobile, to help.
Maybe they are ignoring me, but i have tryed.
Universal's blue tooth signal terrible
Look I had many imate devices and bluetooth sets. The Universal has a very weak bluetooth signal even with normal bluetooths.
I have tried 3 or 4 different bluetooth headsets and they all give me a max of 3 meters. With the Jam and pda2k with the same headsets I used to get 10meters.
I gues this is the reall problem you are facing, the bluetooth reception is terrible on Universal, try being really close like 40CM away and if the sound is good you will know that it is only a reception issue from the universal.
I noted the 40 ~50 cm distance problem when I reviewed my nokia hs-12w a2dp headset about a month ago, it is very irritating. I think it is to do with where the BT chip is placed !!! it is between the keyboard and the battery, from what I could tell of the exploded diagram on this site !! meaning it is surrounded by metal !!! not good .
PS I never have problems connecting my hs12w headset for audio use, however if I take a phone call, after the call has ended I loose AVRCP

Hi cr2,
yes I read about it in IRC Log. But what you like to do is, streaming sound direct to the bluetooth hardware. Universal hardware supports this feature. There are 2 Bluetooth Profiles implemented for, one is called "Handsfree" and one is calles "Headset" and ini Windows Mobile Registry you will find it if you look for "Audio Gateway". The registry values are also documented in the online MSDN Lib. I will post a link, later, if I find it.
What I am doing is A2DP, that means ... all stereo sound will be compressed in software and then send as datastream to the bluetooth device.
Have attached the A2DP specification. Under Linux there is a project calles "bluetooth-alsa", that supports A2DP and Handsfree. Look for it at sourceforge.net.

There are several options here. It can be sent directly
on some phones, or (theoretically) through the phone,
or even redigitized from the analog (for mono).

HTC Hero/Magic Bluetooth

i have a hero rom on my htc magic and everything works perfectly except the bluetooth audio,
is it possible to somehow install the original htc magic bluetooth instead of the one that comes with hero rom to get it working like before?
Bluetooth issues with Hero ROM's are a known, but they are not fixable at the moment.
So either run a ROM where it works or live with bluetooth audio not working.

Yeah a MOD should post a big sticky at the top of this forum about it, gets asked way to often, must be a bigger deal in other countries. I can do without the slow transfer rate and battery sucking feature.

Bluetooth audio is tremendously important if you spend a lot of time on the phone with bluetooth headsets. For me multitouch is one step more important. Now if only 2.0 would come out I could switch back to a rom with bluetooth!

Improve sound quality via BT A2DP

Does anybody know how to improve sound quality for playing music over A2DP profile with Parrot handsfree? On Rhodium i applied some tweaks for quality improve and it was clear and nice to listen, but Leo is not so nice to hear
Thx a lot
I had to tweak my diamond too, looked for tweaks on the HD2 but couldnt find them, but the sound quality is way better on my HD2. I dont think it needs the tweeks tbh.
If i take both, TP2 and HD2 to my car, let play the same song and im switching between HTC's then has got TP2 much more clear and brilliant sound, without any quiet cracklings from tweeter speaker like it is on HD2 :-(
Same problem here, sound quality for a2dp is not what it should be. I tried adding the LineSpeed registry setting, it did improve the overall quality, but did not remove the cracking noise - and in my case I still have frequent skipping and gaps in the audio playback. Have not yet had a reply for Tech Support, and if/when I do, I don't think it'll be a very intelligable one...
Yop, i think too, that the answer will be unusable, or maybe they tell you that u should do a Hard rst :-D
First time i connected it to HF and let music play i thought that is a bad quality song, but it isn't :-(
Anyone idea?
I know there are some settings to definately improve the sound of A2DP. I've added them on my previous HD, and worked perfectly after that! I just found some things you might try (I just applied them myself as well, but havent tested them yet; I'm almost sure they'll work):
http://forum.xda-developers.com/showthread.php?t=308752&highlight=A2DP+settings+bitpool
If I'll find the previost post which I applied in the past on my HD, I'll let you know. If the one I just posted will work, I'll let you know as well of course, because the litteral and figural crappy sound of A2DP is something I hate as well...
Edit:
Take a look at those settings as well from J-A-J-O at page 6:
http://forum.xda-developers.com/showthread.php?p=1677577#post1677577
Again, I don't know exactly if it were those settings, but they sound familiar to me. I'm also busy trying to get the best sound quality via bluetooth out of my HD2

The XDA tweaks are rubbish and do not work. I currently have a call out with HTC.
I have removed all reg tweaks from my HTC and now can get A2DP working on my parrot ONLY in the following situation:-
(1) Reboot HD2 (hold end key and select off. then switch on)
(2) Allow to connect to Parrott (will connect handsfree first)
(3) Open bluetooth from settings and select stereo audio and select connect.
(4) select handsfree and select disconnect.
(5) Press PLAY on the parrott kit
By doing this I get no skipping at all and the quality is good. I have no tweaks running.
This is obv crap and is why I have been speaking to HTC all week.
Steps 1-5 have to be strictly followed for this to work.
The BT tweaks mentioned on this forum do not work. They only appear to work as you have rebooted. After using the HD2 for a while and then connecting A2DP, skipping will occur again.
Try steps above and it will work.
Interesting! I'll try that on mine. Greenfrog all of those links and bitpool settings relate to the Microsoft Bluetooth stack. However the HD2 uses the Widcomm stack so those registry settings can't be made.
I too am fed up of the bluetooth sound quality. How can they assume we'll be happy with this mediocre sound?! I can't see why with a 1Ghz processor it skips.
Have you guys tried the A2DP with the latest 1.61 ROM? I'm still on 1.43....
When I find my 'goldcard' that I made I'll try it on 1.61 and let you know
We'll get there in the end....this is really my only bugbear with the HD2, so it would be good to get it fixed!!!
There got to be a way!
I, too, am really p***ed off by the bad audio quality i get using stereo blutooth. It's really an issue with the HTC HD2 and apparently no pro reviews pointed it out!!! I use it with the sony DR-50 which are one the best A2DP headphones out there, but the sound is horrible Please help...
I'm too suffering from the A2DP situation...
The Linespeed registry hack helps me on some devices ( HKML\Software\Widcomm\Plugins\AV add DWORD Linespeed with value between 64 and 512, the higher the better sound but higher probabilty for skipping).
With Linespeed = 320 sound is great and I have no skipping with a Sony DR-BT160AS. But: My Motorola S9 badly skips unless I have it very close to the HD2. Linespeed = 256 is working ok with both devices...
BUT:
I also have a blueLino A2DP Receiver which has a bad quality on both settings, at least on some songs. That's really disturbing.
Just a quick update, I've just flashed to 1.61 and it makes no difference. Default A2DP sound quality is unacceptable. Grr

Well, first I have to say I don't have the 'skipping' issue at all. I have my HD2 connected via bluetooth to my Pioneer DEH-P7100BT car radio. I have a clear connection when calling, but when playing music via bluetooth, I have the 'hissing' issue.
Next is that I have to admit that when I changed the settings according to my previous solution, did work a little, but not as it supposed to. When I had my previous Touch HD if found a link which worked perferctly for me! When I changed to those settings, the hissing were gone completely and the sound quality improved to CD level. Although, I'm still searching those ones again for my HD2 at the moment....
So, conclusion this far is that it totally depends on the hardware which you are connected to as well.

@Greenfrog:
I guess the bitpool settings which worked well on my HD as well, only work when using the MS Bluetooth stack. The HD2 uses the WIDCOMM Bluetooth stack, I haven't found a noticable difference.
The LineSpeed registry setting does improve overall audio quality, but I still have skipping and playback gaps. Very poor performance for the performance beast the HD2 is. I urge everyone to report this to HTC (I did) - this is really unacceptable.
I will also report this to HTC. I am so frustrated by it tbh
As Moses posted...I had linespeed set up on my TP2 and the sound was great, but now i have no time to test it now, can someone other test regitry key?
Bluetooth settings
Can be found here HKLM\Software\WIDCOMM\
A2DP Tweak Provided by R_phAn (Please note this will not work with all devices)
As we know from the past, each device has it's own preferences and capabilities (So you'll have to play around)
Managed to improve soundquality by adding DWORD 'LineSpeed' to HKLM\Software\WIDCOMM\Plugin\AV\ with a value of 320.
it is posted here for TouchPro2: http://forum.xda-developers.com/showthread.php?t=524655
Edit: I tryied it tomorrow morning and it is still the horrible quality, poor music quality and during the call skipping :-/

Okay, thanks a lot for this update! I was really unaware about the different stack, so I don't have to look further for the the previous links anymore... I'll try to add linespeed as well to see if it works with my Pioneer car radio. I hope it will...
There should be an answer for sure for this issue. I also cannot understand why it have to be this difficult. The previous solution did work very well. Why have they changed to the other stack anyway? Does someone know that?
I'm running the 1.48 ROM btw.
GreenFrog
I found one thing, i'm using SPB Radio for online streaming, when im listening in my car streamed radio then the sound quality is excelent...? How is that possible?
That's a very good question.
I experimented a bit with different quality settings during mp3 encoding. I found out that there indeed is a connection between the quality settings of the mp3 file and the badness of the sound quality, at least to a specific degree.
The most important setting seemed to be the stereo setting. If I set a song to "Joint Stereo" its by far better than normal stereo, although not perfect, yet. That's very confusing.
Do you know the settings of the radio channels you can stream with good quality? Maybe that would be worth a test.
--Update--
So I had a predictably useless response from HTC. Namely 'have you tried unpairing and repairing' and 'your device may not be fully compatible, please check our website for a list of compatible devices'.
Useless indeed. Their compatible devices amount to 3 items! The phone is either A2DP or it isn't. There are no compatibility options - it's happening to us all.
So, I haven't mustered up the energy to continue onto the next pointless exchange of basic trial and error possibilities. No doubt their next reply will be "have you tried rebooting the phone"...
Anyway, I digress. I noticed something today. I put on a new album to my SD card and out of nowhere the skipping was worse than ever. Audiomanager is always on the lookout for new songs as you may have realised. When you have music playing, a small circle rotates to show the player is searching. During searches whether or not you've introduced new mp3's to your device, it always makes the skipping far worse. When my circle had come to a stop, then the audio was fine....with very rare pauses and skips.
Still there but much less obvious.
Well that's my latest update and I will continue my investigation. I wonder if this skipping occurs in other music programs? ie wmp or pocket player? Has anyone tried?
Great work, guys. Nice to see a lot of people looking for a solution. I REALLY want to get this A2DP thing working right, it is bugging me a lot, and I'd like it to be fixed when I'm going on vacation (I'll be driving to two straight days, and would love to listen to my own music then). That'll be in about six weeks, so there's still some time left.
I'll try SPB radio myself, see if that causes the same amount of skipping. It could be that it is not the BT link causing the skipping and pauzes, but the audiomanager itself. That would be a bummer, because fixing that is probably way beyond what we can do here, and we'll have to hope for a HTC fix or a custom rom with an older and better working version of the audiomanager.
In my search for possible solutions, I found the priority of the A2DP can be altered. I've added the reg Dword value "Priority256" to HKLM/Drivers/BuiltIn/BtA2dpSnd, with different values. If the value is too high (150+), nothing changes. Set it too low - I tried 60 - and BlueTooth fails to start altogether. I've now set it 149, and it seemed to work, but haven't done extensive testing to see if the skips/pauzes don't return. Will get back on that.

I've tried PocketMusic, qualitywise no difference. I don't remember if it had the same skipping / pauzes problem, but the problem for me was it doesn't work with the AVRCP, so I can't play/pauze/ff/rew with my remote, and having to use the screen while driving is a pain - I've mounted my device quite high. I was really hoping to use the inbuilt musicplayer

[dev request] a2dp

Hey everybody,
I hope this can start a bigger awareness/activity on the goal to get a usable bluetooth audio protocol with Android on the HD2.
The Story
There hardly ever are threads or posts adressing this, which I can not understand. For me personally this is one of the 5 most important features in my handset. For example I can live very well with having to reset my 3G connection from time to time, but I can not stand having no A2DP. (I loved how WinMo does this on the HD2, fading down the music to make navigational instructions understandable. before you ask: after having android I simply dont want to go back to WinMo... it would make me sad.)
The Problem
As of what I know, A2DP sound quality ist directly linked to something in the Kernels. Until Hastarin 4.x the sound was beyond ****ty, but then there was an improvement, though it was not mentioned in Hastarins changelog. Was it an accidental improvement?
Anyway, since then the sound quality has been on the same level, being kind of working, but with an awful weird overweight on low frequncy tones. This can not be leveld out by the amps of any of my receiving devices.
Since bluetooth pairing works so well, and the A2DP transfer essentially works, i hope that it can not be the biggest issue to get the quality straight. -for a dev or cook, I mean
Please start a lively and constructive discussion! Now! Find a fix, and be sure that my donation will buy your next beers/organic lemonades/what ever you're in to.
I dont know what are you talking about..I use A2DP every day with great sound quality..It would have been useful if you posted your configuration on the device, Rom, Kernel, Build, and Bluetooth headset so we could maybe try to help you out..
I use:
WM ChuckyDroid
Build is NexusHD2-FRG83_V1.5 with both Hastarin r7.7 and michyprima R11
Bluetooth headset: Plantronics p590 (quite an old one but works great)
Everything works great..please be more specific about your problem
Cheers
I use A2DP on a daily basis as well and it works flawlessly on ever build I have tried
Are you you kidding me?
Since i tried a lot of ROM/Radio/Kernel combinations i thought this made no difference... I was quite sure this must be a development problem.
right now I use:
WinMo CleanEx Rom
Radio 2.14
Mdeejay evo sense 2.3 with Hastarin r7.9
Bevore that I mainly used a Dutty ROM and the MattC sense v1.8 with basically every Hastarin Kernel.
I've testet it every time on two different A2DP enabled stereos, and as described the sound quality is poor.
Can others confiirm having a good (or bad) sound quality over bluetooth?
Zero issues on the ones I've tested.

Devices
Maybe you and everyone should post their devices to see if that is the issue. I have a plantronics 510. It works perfect in WM but doesn't even show an a2dp profile in any android build. I would love to have crappy quality if I could even connect.
BTW: what is a good working headset that is confirmed to work with android bluetooth a2dp?
Yes, the quality is quite low on A2DP. Tested on my SE HBH-DS200. That headset is superb in WinMo.

Bluetooth A2DP
A2DP is a bag of different codecs from decent to bad. All Bluetooth devices that support are only required to support the minimum codec (not very good). Better ones including AAC and Apt-X are available but cost a bunch for a device mfr to include. Some phones, like iPhone have a lousy codec (possibly updated in the next ios release), others, like Nokia, seem pretty good. The tubby bass is a signature of the minimum codec. I don't know if the codec can be added through the OS since it lives in the BT chip. If you have good stuff in the phone it doesn't help at the speaker/headphone end if they don't have it as well.
We should also push to make sure that AVRCP profile is also supported so we have remote control (missing in iPhone until recently).

Sony MW600

For anyone who is interested i have a sony mw600 bluetooth headset which i have tried with different platforms on the HD2 with varying success.
However i now have wp7 mango installed and it works almost perfectly with the headset and is even showing the song titles.
Only issue i find is that sometimes when you use voice command it will call the number but not transfer the audio to the headset - but you can then transfer in call by just pressing the call button
mango seems to be running really well on the hd2 now.
many thanks to all the developers and everyone on this site
Hi redsufi!
In the matter of fact I am very interested that you have the MW600. Your timing also was perfect. I know it's a bit hassle but I wonder if you could help me with any of these things concerning the MW600?

Hello!
To those of you with the MW600 here, I have a couple questions to you:
1) Can you use this as a microphone only device for let's say Skype and other voice communication programs (Ventrilo etc)? Meaning you wouldn't have any earbuds/headset plugged in the MW600 but only use its built in bluetooth microphone and listen through other (wireless) headphones that are plugged straight into the PC?
In other words: does the MW600 work as a microphone without having anything plugged into it? Could someone please test that? I would love to have a wireless mic on my shirt somewhere.
2) How good is the range inside a normal house? Does a single wall block almost all of it or can you wander around many rooms?
3) It was somewhat covered here but would you recommend it for its microphone quality or are there better ones around?
4) I realize this isn't under the Galaxy Tab section, but has anyone tried this device with that? How was it?
Thanks a lot in advance!

Hi there
I dont really use skype as its not available with windows phone 7 yet but with normal voice calls you can use the microphone wihtout the headphones attached so don't see that it would be a problem.
The range i think is 10metres and its fine through walls only when you get to the limit it just cuts off -
i find the quality of the mic and with listening to music is great
regarding the galaxy tab dont have one of these so you could try googling it
its a sony product so usually would only have full suppport of all the features with another sony product but all the functions work fine with wp7 on hd2 as well as wm6.5 - there were some issues wiht various android and nodo builds.
Alright, sounds good. Those helped a ton, thank you very much for the information!
Enjoy your MW600. I will soon probably too.
Works great with the Galaxy tab
