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)

I also have this Problem. Sometimes, i have to press, the button twice, sometimes i have to hold it. But the problem apears only, on resume.

Yes, that's realy evil ... I also have that. Reconnecting of Handsfree works fine.

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
Radio-Version: 1.10.03
Protokoll-Version: 42.44.P8
ExtROM-Version: 1.30.223 GER
Windows Version is 5.1.195 (Build 14847.2.0.0)

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;

You can see my (and some others) experiences with A2DP and some stuff we have tried to fix/handle it as good as possible;

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

How do you play sounds over bluetooth ?
I'm trying to understand the routes of analog and digital
sound data and how to control them.

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).

Software is not a problem. We need to understand

Summary: Voicecommand via Bluetooth [STILL UNDONE]

After playing around some days (and yes: i read through a lot of threats) i think that this problem (using a bluetooth headset to activate ms voicecommand for dialing and so on) is not only bugging me but a lot of others.
Thats why I want to start ANOTHER, more structured thread about this topic. If something is wrong, please correct me!
WANTED SOLUTION:
Most of you want to use voicecommand activated via a bluetooth device... in your car beside TomTom for example.
PREPARATION: Headset working
I assume that you already got your device working. For myself, I am testing with Supertooth II and a Nokia BH200 hands-free device.
PROBLEM 1: TRIGGERING
First off all, voicecommand needs to be "started" when you press a button on the headset. Usually, the application "windows/sddialer.exe" is launched when bluetooth gets a "voicecommand"-commando.
(Some headsets got their own button, some wants kinda double-click, others want their button hold for some seconds to do so...)
This problem can be solved by changing a key in the registry:
Code:
HKEY_LOCAL_MACHINE/Software/OEM/VoiceCommand/
..Then change the path value to:
\Program Files\Voice Command\voicecmd.exe
(or whereever you installed your voicecommand exe-file!)
Okay. Now the right application is launched when tapping on your bluetooth headset. But here you may encounter the next problem: It works only once.
PROBLEM 2: IT WORKS ONLY ONCE
That problem seems to be caused by voicecommand, because the gateway is left open after useage. (I have no idea if this is correct - i am just citing the opinion of some threads)
There are some attempts to solve this:
Darryl Burlings "Voice Enable": http://www.burling.co.nz/downloads.aspx
Project VCABT http://forum.xda-developers.com/viewtopic.php?t=23558&highlight=vcabt
VCBTFixer0.01.
JETware Hands-free Extension for Windows Mobile phones
http://www.jetwaremobile.com/
I tried them all and for me (german T-Mobile Rom 2.21) only Jetware's Tool worked. A reason MAY be that some of the hacks (vcabt, VoiceEnable,VCBTFixer0.01.zip) only work with an english ROM where all paths are correct: /programs and not /programme)
PROBLEM 3: Correct Audiotransfer
Some users report that it seems like there is still Wizards microphone in use - and NOT the one of the bluetooth device. Others again claim that voicecommands "answer" isnt delivered back to the headset but speaken via Wizards speakers... Since I used Jetwares Tool i didnt had that problem.
PROBLEM 4: Recognition Quality
Lets say you got somehow the correct and everlasting triggering of voicecommand via bluetooth working... then you may find out that recognition ends up with very poor quality.
Here a question for the "pros" in here: Could it be possible that this problem is related to poor bitrates in the audiotransmission via bluetooth? Could we increase recognition quality by tweaking that bitrate? Or will that end up with another problems (bt-bandwidth, cpupower while coding/encoding)?
PROBLEM 5: Interfering with other applications
Thats a future question... When everything works well with voicecommand - then you maybe want to use it in your car to have your hands free. And what else do most of us have there too? TomTom (or another navigation tool)!
So how will that work together with your voicecommand/bluetooth environment? Will TomTom "speak" via your headset too? Will the bluetooth gps mouse keep on working without problems?
And last but not least: Will you still be able to use your phone as a "phone" then?
Please share your ideas about theese problems... and if anyone got everything up and running (Voicecommand & Bluetooth, TomTom / GPS) it would be *very* appreciated if you could post a well written Tutorial / Howto
Regards, Licht

Good luck - for what its worth it works fine with certain BT headsets like the Moto HS850. Just the reg key does it.
Only thing is you have to hit the button on the BT headset 2-3 times sometimes to get it to work but it works perfectly otherwise.
Would LOVE to have a fix that would let me use with all headsets.
How does the jetware stuff work? I heard it screws up some other things?

Cause of "works only once" problem discovered?
I've gone through 4 different headsets with my Wizard and I found at least one commonality to which ones suffered the "works only once" problem:
All of the ones that had this problem were BT 2.0 headsets. The ones that worked fine were all BT 1.x headsets.
I also verified that on my new TyTN (which natively support BT 2.0) the BT 2.0 headsets worked correctly (no "works only once").
Not that this is any consolation to anyone with a BT 2.0 headset and a Wizard, but might help those looking for a new headset.

Changed over to Tytn... works perfectly without any hacks

here's my FWIW answer:
After extensive reading here and at Hofo, I settled on a Plantronics 510. Installed Burlings app and it worked. I hold the button to turn on VC (it will also wake the device from standby if its sleeping, even if its locked) and say my command. It will reply through the headset speaker. After that all audio is oing through my BT headset. (If you have VC telling you who's calling and telling you your appointments thats pretty nice, but if the phone rings you might need some new underwear)
Another long push of the headset button return audio to teh MDA's speakers. If I need to use VC again, I start all over. It sounds more complicated thatn it is in reality.
Recognition is so-so. I don't really use it in my pickup (its hot so my windows are down most of the time), but its pretty good in my car. I have to repeat myself maybe 10% of the time, at most.
Not sure how well written that was, sorry. if anyone has any questions I'd be glad to answer them. I've been pretty pleased with the combo. Especially since I got the 510 for $40 from amazon.

BTAudioToogle for Hermes

Hi,
i can't use the BTAudioToogle Tool for my XDA trion.
Someone the same problem ?
or better:
Someone with a solution here ?

Same for me. I have enabled BTaudiotoggle, I can hear the headset (Motorola HS850) go live but the audio either from WM player or TCMP still comes from the speaker and not the headset.
Hope someone comes up with the answer soon.
Rob

Got the same problem. No sound from BT.

Had something similiar to this with my old unit, to fully enable it I would hit the headset button (which now starts up voice command, let it time out, and then play whatever music i wanted to. I would verify that now but i am at work, and don't think they would appreciate the music blaring if i am wrong on this one

When I hit the button on the headset, it starts the Voice Dialer, the audio cuts in for a second or two, then drops back to the device speaker.
It nearly works, hope someone can hack this soon, just whats needed for podcasts and the like. No good for music tho!
Rob

I would also be very interested in a solution to this problem as I used to use BTaudiotoggle to listen to Tomtom commands in the car (normally have the music too loud to hear the commands through the loudspeaker ).
Worked great with my XDA Mini S but doesn't work with my new MDA Vario II and I didn't really want to have to buy stereo headphones, just wanted to be able to use my standard mono bluetooth headset like before.
If there is no way of using this program, are there any other programs that will send all audio to a mono BT Headset?

yep would really like an updated version of BTaudio too so i can listen to some audio books via my mono headset

You should test the trial version of bluemusic from teksoftco.
www.teksoftco.com . It gives ou a full help file on how to use the software and you have 30 sec to test that it working. I know that it works on the devices having TI Omap processors so it should work for all of you guys.
Cheers,
Raul

Just tried it out. It does the same thing that the other sotware does, mainly enable the headset where you can hear a hiss out of it, but still kees playing out of the back speaker.

My experience is a rassah's. All the Bluemusic software appears to do on my Vario II is cause the bluetooth headset to hiss slightly (whilst sound is still blasted out of the phone's speaker).
Also FWIW the teksoftco site doesn't appear to work too well on the PIE browser - defaulting to a no frames version with just a login box as far as I can see.
Needless to say I have uninstalled the software again.
Rufus.

@RufusA and @rassah guys you should check if you don't have the same problem as ulischultz in this thread :
http://forum.xda-developers.com/viewtopic.php?t=61739
We already tested the software with him on his treo device and as you can see in the thread " after pressing the button on the headset, the sound was redirected". This is mentioned in the help section of the software. ( on the universal/exec for example this step is not needed)
@RufusA - thanks for visiting the ppc version of the webpage (which is still under construction) - even though the subject is irelevant in this topic. I will send you a PM when its finished and tell me your opinion then (even though you have to admit that not many companies have a ppc version of their website - not to mention the smaller ones like ours).
If the problem still persists there is an opened thread on the forum :
http://www.teksoftco.com/forum/viewtopic.php?t=162
Please submit all the malfunctionality and we will fix them.
Cheers,
rain

I downloaded the trial too and had the same problem as before unfortunately.
I did get a little further in so much as, if I pressed the call button on my BT Headset as per the instructions, I could get the music/audio transferred to the headset for approx. 5 seconds but then it would revert back to the phones loudspeaker. I couldn't get the 30 seconds that the trial software advertises
Fingers crossed someone will be able to work out a fix for this soon.

Thanks Nicky for the input. As i see the problem of bt headset being disconnected after 5-10 sec is a general one (and unfortunatelly is a problem in the RUU). We are trying to find a workarround with ulischultz but wouldn't want to get to driver level as clearly it will be fixed by HTC in the next RUU release if they don't want this devices smashed to their heads.
I will keep you updated if we find a solution for the interrupt issue.
Regards,
Raul

Solution
I have identified a solution to this which is working nearly perfectly for me. However, if you do use this then using the BT headset to trigger the voice dial/voice command/voice commander will no longer work.
Acquire a copy of of the BTAudioToggle software inc. BTAudioOn.exe
Copy this to a location on the phone.
Using a registry editor amend the following entries from
HKEY_LOCAL_MACHINE\SOFTWARE\OEM\VoiceCommand
Path = location of BTAudioOn.Exe
e.g. Path = \Program Files\BTAudio\BTAudioOn.Exe
VoiceCmdDuration = 86400 (DEC) = 24 hours
This says for how long (in seconds) the audio will be passed to the headset for before timing out.
This however, will timeout earlier if no audio is coming through. I am not sure what will happen if something like TomTom is running but not speaking for a while. I have not performed timings as yet.
To activate audio through headset, press the main control button of the headset as if answering call/activating voice command etc. To deactivate, just press the button again.
Voice control apps will still work, but must be triggered from the phone itself, but voice will be picked up by the BT headset.
There appear to be some small bugs with this, such as after a phone call, using headset or not, the audio will stop being passed after hangup.
Please let me know if this work for you!

Looks an interesting solution. I've installed BTAudioOn on my storage card, and changed the VoiceCommand Path entry.
However I couldn't find a VoiceCmdDuraion entry under
HKEY_LOCAL_MACHINE\SOFTWARE\OEM\VoiceCommand
so I've added a new DWord of that name with the value 86400.
Yet this doesn't appear to have made a significant difference i.e. Pressing talk button on Jabra headset produces 10 secs of sound before "timing" out.
Have I made a mistake, or do I need to have something else installed to get this to work?
TIA - Rufus.

I was going to try and make the suggested changes to the registry but I don't know how and am not sure what program I need to do it.
Could someone please let me know what program I need to install to be able to change the registry?
Thanks

Vs1979:
IT REALLY WORKS!!!!!!!!!
I can't tell you how happy I am!!!!
I did it the way you described it. However I also did not have an entry "VoiceCmdDuration" I created the DWORD-entry and it works now!
Great!
Thanks very much for that great solution!

@RufusA
As i gave you the link to the other thread you're not the only user experiencing this. There are several others complaining about this RUU bug.
@Nicky
You need to install a ppc 2005 regeditor (for example Resco Explorer has one built in, or you can find one on buzzdev site).

Hi,
Did you Soft reset your device?
I made the registry change only, have not installed BTAudioOn and all my Voice command Audio etc... now comes through the headset and does not time out after a few seconds. I did find though that decreasing this value to lets say 60, would actually time the audio feed out even if not in use so I have stuck in a huge figure, will still need to do more testing to see if drains the battery any quicker and see if I can find another stirng which will do more for me.

Hi,
it work not for me
i have changed the path to \xx\BTAudioOn.EXE
i have add the VoiceDuration = 86400 (DWord DEC)
but it is the same problem, after 2 seconds the sound goes back to PPC.

The only reson I don't use wm5/wm6 is BT stereo SKIPPING~

When I use the A2DP in wm5/6 I tray all versions BT stack~but no one could work,so I chose 2003se,IT's best for BT A2DP.
Why Helmi Do not fix that?Dose this really hard?

Yes, it's that hard to fix that. The only way we could get wm5/wm6 working flawless on BA is if we had the source code for the drivers and the testing/debug equipment.
If you know someone that works at HTC you could ask them to look for the BA devkit and sourcecodes on the storage rom... hehehe

Mine didn't skip with WM5 and did not skip when I first flashed WM6. Now it does. When I was messing around trying to connect to bluetooth devices (I couldn't connect properly), it stopped skipping for a while. I don't know if this gives any clues.

I know a way to prevented this bug,but not prefectly.
Use regedit tool,open to find software\widcom\plugin\av
add 3 dwords
Linespeed 320 (10+)
Blocks 16 or 32
Subbands 16
You will see the music quality is prefect
but the skipping frequency is above normal~
When using the asus p535,this way will surly improve the quality~and it no skipping,so I thing it must be the bug from the System~
Use win2003 have no such foolish bug.Now I set my pc back up my pda every time connected it with PC~Store the phone book in simcard~
I have no choice

Toxi,
Thanks. I couldn't add the Dword settings which you suggested because I had no Widcom file. So I loaded Helmi's 1.7 Broadcom BT driver. (Always wanted to try it. The Broadcom BT drivers alway better. Immediately after installing, my BA played music better alone and with my BT headsets. Adding the Hemi 1.7 BT cab, added the Widcom file which allowed me to add the Dword registry changes. The music sounds almost perfect.
I tested the BA with these three BT Stereo Headsets: Motorola S9 headsets; Chinese Copy Motorola BT820; and I-Phono RX450. The Motorola S9 works (It didn't at all with the MS WM6 BT Drivers). The S9 would only work if it's 12 to 18" from the BA. That's unacceptable. The BT820 chinese knockoffs skipped as usual (the skip some with every device cause they're knockoffs). The I-Phono worked perfectly with crisp clear sound and no skipping. I can also get further away from the BA but certainly not more than 3 feet without trouble.
In conclusion: Helmis Broadcom 1.7 cab worked to fix the sound problems completely with and without using the headsets. The newer headsets such as the S9 don't work all that well with the BA.
I hope this is helpful for others not satisfied with the music quality of the BA running WM6.
I wish HTC would make a Blue Angle II.

Bluetooth AD2P & Carkit connection

There are a lot of problems with carkit connections & the HD2.
I tried several things to get it working without success.
When I try to connect to the JVC KD-AVX44 it connects but give no sound at all. (making 2 connections, handsfree & stereo audio)
Then I tried the registry tweak mentioned into this forum and had success once. I was very happy because also the title track was shown onto the JVC display and also the phone was functioning ok both ways.
The sound trough AD2P was perfect. Only one time.
After that i get a lot of disconnects.
Then I tried to make only connection with the phone function and this is working ok now. When I want to make the connection trough AD2P then the problem is back. Also when you make it without making the phone connection
So I think the problem lies into the stereo connection. For instance when you skip a track onto the JVC then the connection will be lost and reconect again and giving 2 seconds of sound and then it's quiet again.
Also when to 2 connections exists the phone is blocked by incomming calls because it's thinking it's connected so the earpiece & mic are dead at that time. And also the radio.

Did you try the LineSpeed setting to 256 in the AV key of the Widcomm registry settings ?
Don't know if it could help in your case but it did for me, I don't have disconnects with my Sony headphones anymore and sound is better.

Bluetooth
Ok thx I will give it a try and post the results.

which registry tweak did you applied first, cause i too keep having issues...?

tweak
Change Registry setting:
HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\Sys
Add the DWORD setting COD=5374476
This makes devices see the HD2 as a 'Normal' phone

Do I have to add this line somewhere? I found the AV key into widcomm but the line was not there

Ok i make this in my BMW X5 and one of problems is solved - HD2 working correct when i am on call and power the car, but i have another problem - after 5 - 6 min on call Bluetooth connections is droped and i can't lisen nothing from Car or for Phone - i must to press Menu and switch off Hands free to continue conversation.

Ok but are you also making stereo connection. I only have the handsfree conected at this time and then the connection is stable. Only with the A2DP it goes wrong.

Strange, so far I didn't experience any disconnection.
I have conversations during more than 20 minutes daily and line quality is far better than with my Diamond, with no drops.
With the Diamond I had the BT stopping regularily on the phone, it was very annoying because I always discovered it when receiving a call and not being able to answer.
So far it didn't happen on the HD2, but it is really too soon to jump to any conclusion.
I don't use A2DP in the car as I didn't order the option, which I viewed as useless because the hard disk capacity of the iDrive is sufficient to hold a good collection, the audio quality and functionality is much better and I can still connect the phone to the USB plug as mass storage if I want to play or transfer something from it or any memory stick or external HD.
So maybe not having the A2DP profile active may help also.

I also not any problem with my old HTD HD and Cruize ... but with HD2 i have this issue.
Today i receive answer of my ticket from HTC: they offer me to contact with BMW and to ask them why they not support HD2 ... I think this is stupid becouse every new device must support old protocols and older devices.
Now the choice is to change Car or Phone ... sorry but HD2 not have any chance to survive.

Yes how lousy is that
Got the same answer first, but they realised that BMW coudn't recall thousands of vehicles to do a BT upgrade just because HTC decided to adopt the crapy Widcomm BT stack.
So they say they are working on a fix, but given how many issues there are with this stack, they better switch back to the old MS stack instead.
To be clear, it is the Widcomm stack at fault here, not BMW. Every single phone not equipped with this stack, I could try on the BMW, worked flawlesly.
I hope they will recognise this officialy and not blame the others each time a customer opens a ticket about these flaws.
In the meantime, the registry hack works perfectly for handsfree profile, but it seems it doesn't fix everything when the A2DP profile is activated.

After much playing around - I found a linespeed of 300 works best for the HD2. 256 still has questionable quality and 320 for some reason skips a lot. Reducing it to 300 seems to be a workable equilibrium!
