MDA2 Carkit is silent after upgrading ROM

Hi,
I've got a problem with my carkit (O2 XDA-Carkit) after I upgrade to the new ROM-Version of T-Mobile (1.60).
With the old Rom-Version, the carkit works as a loadspeaker for all kind of sound. The voice-instructions from tomtom for example, came out of the carkit-speaker loud and clearly. Each kind of sound, the device made, came out of the speaker of the carkit.
Now, after upgrading to the new ROM, only the telephone works with the speaker of the carkit. With Incoming or outgoing calls I can use the carkit as usual...the speaker works and the mikro works also. But every other sound (e.g. tomtom voice-instructions) came direktly out of the speaker of the mda2 in a poor quality.
Some hints, how I could use my carkit again as a speaker for all kind of sound without goinig back to the old ROM ?
Any other kind of hints...maybe to use a bluetooth headset therefor (so that all kind of sound came out of the headset....not only telephone...I've got a Plantronics Headset...but also only the telephone works)
thx for help
best regards
rob.

Yep.......I have the same problem here.......don't know why they changed settings on the handsfree profile here.
Another thing you will find out is that the charging is very slow on the XDA carkit with the XDA II. If you run TomTom, Yeti and a bright screen the xda II will not charge, but drain!!
It has something to do with the wiring of the interface, but unless someone will come up with a solution I will go for a new carkit or a BT solution. (It's a bloody shame though it doesn't work properly with the XDA carkit! :evil: )

Hi,
the charging-problem is also a mess.
I think, the problem is only the GPS-driver from tomtom. In my tests, only when the GPS-driver is loaded, the battery-power goes down. With stopping the GPS-driver, the battery will charge again, but only, if the battery-power is more than about 75 - 80%.
If the battery is less than 75%, it will not charge at all, even if, there is no App runnung and the screen is off.
You said, you will go for a new carkit or bluetooth-solution. Do you know a carkit or bluetooth-solution, wich offers the feature, that all sounds (tomtom instuctions...etc.) came out of a loadspeaker or thru a headset (without connecting the wired headphone ;-)
As far as I know, at the moment all devices works only with the telephone-funktion....
best regards
rob.

Same here,
i have build my own carkit, and have put ground to pin 19,
sound was normally going though the connector to my car stereo
now it doenst anymore :evil:
I am sure this isnt a hardware thing it is software
could be the settings on the handsfree profile. on the xda2...
this is very very frustrating. just being finished with my carkit and now i cant use it anymore
also you cant set the phone to speakermode anymore..

I am sure this isnt a hardware thing it is software
could be the settings on the handsfree profile. on the xda2...

Does anybody know how to change this back?

I found that the registry points to a certain file in your windows directory: HandsFree_Dll.dll
(I found this here: HKLM\Services\Handsfree)
Can someone with the old 1.03 ROM please upload this file so i can try if this solves the problem...
TIA,
Max

Akira, Max :
I am building my own car kit, and have no success.
I do not obtain audio out with or without grounding pin 19.
I'm running Rom 1.60.00WWE.
Did you solve your problem ??

I must correct my last update.
I obtain audio when in phone mode, but not during playing waves or TomTom directions. Even Ring Tones do not go out trough the bottom connector.
So is it a software problem ?
Can it be corrected ?

i resently bought a heaset sagem BT sh1, (BT stereo headphone) and tryed to use them on my universal originaly with the 02 uk latest vanila rom, but it didn't reconised the headphone as such only headset, so i search on the forum and find that it was because of the missing A2Dp stuuf, so i upgraded and flashed the rom to WM6 wich resolved some of the problem but not totaly,
The headset work not problem to Lisen phone call and stuff, i can even lisen to the sound of the universal ok, screen tap and so one,
but when i start media player to lisen music, it does work for 4 second and then it stop, it doesn't shutter, it just stop, and work again for 4 second only if i close mediaplayer, and it work again for 4 second, i try the reg hack but didn't change anything, i try the a2dp upgrade as well no success,
i try other player no success, what get me is the fact that i cannot lisen any sound that are longer than a few second,
can anyone help me,
thanks a lot
ps i did pass almost all day looking for a solution on my own, without result.

Hi!
Using "Resco Registry" or another registry editor program, find the following key:
HKEY_LOCAL_MACHINE\Drivers\BuiltIn\BtA2dpSnd
add new DWORD:
Priority256 with value 250 (decimal)
This should solve any lag problems. But to get hi-quality sound, you also need to tweak parameters here:
HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\A2DP\Settings
These are the values that result in the best possible sound:
UseJointStereo = 0
BitPool = 58
MaxSupportedBitPool = 60
MinSupportedBitPool = 30
Good luck
WBR, Draco.

hey thanks for the tips but it didn't work, the probleme isn't that i have lag, but that i simply have no sound that is longer than a few second. exept on headset phone mode, and the quality is very good anyway, after i did that reg hack it was even worse, (no offance intended) no i can't have any sound longer than one sec, and in the registery under HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\A2 DP\Settings
i didn't have any settings, not one. can it be sommthing missing in my wM6 rom ?

Hi,
I have a similar problem using Helmi WM6 rom...I have been using itech bluetooth headset for almost a year now without problems, after switching to WM6, each time my phone rings, i have to press once to connect the bluetooth to the phone and another time to answer,,,It was fine with the WM5 roms..any ideas?
Cheers!

WM6 A2DP settings

Hi,
I am using O2 xda mini s, and i just bought a sony ericson HBH-DS970 stereo bluetooth earphones.
I am using WM6 Xplorer Rom and radio version 02.25.11.
Currently I am a bit frustrated with my bluetooth earphone as the quality is very poor eventhough I read that the quality of the sound if used with other bluetooth handphone / pocket PC is superb.
I have ben searching this forum to either tweaks the registry or any patch to improve the sound but currently I'm still lost. I found one old post (WM5) which guide us to tweaks -> HKLM/software/microsoft/bluetooth/a2dp/settings....
but my problem is that there is no settings folder under my a2dp, there are 4 folder with label 1,2,3,4.
Are there any way i can improve the sound quality???
will changing the radio rom affect the quality of bluetooth reception??
Please enlighten me..
Thanks

Try the settings from cduncan...
If there is no registry entry, you will have to manually put them.
You can change the bitpool setting for quality of music.
HTH

Cheers Sids,
I have already do as you said... previously went to that post but feel lost, and since the thread have over 100 pages, therefore i feel inappropriate to ask you or duncan.
One more thing though, can i ask you what is your personal preference on those settings?? I cant put a lot of bass, because it will sound terrible, like broken speaker.. what todo??
cheers mate
p/s My problem is that the quality of the sound that coming out of my BT earphone is just poor (although others are highly recommending this DS970). I have no problem with pairing it with my wizard or the playback.
I have play around with the BitPool and the only difference that I notice was the volume level, not the sound quality. any advice??
One more thing, is the selection of Radio Rom have any effect to the quality of the bluetooth signal i.e. to the output in my BT earphone??? Help...
Thanks again

Hi,
I cant say about your BT headsets. But I confirmed these things - Updated firmware from the manufacturer (Jabra for me) and the quality with other A2DP enabled (maybe nokia/SE) phone.
I have set my bitpool setting to 60 which is Farias default, but he placed the reg entry in AD2P folder instead of A2DP by mistake.
I am using equalizer settings with TCPMP for the nice sound, which I dont get with Windows Media Player. Maybe you could try that out.
Even after those settings and tweakings, I dont think BT headsets can replace wired headsets for an audiophile. You will only just get passable sound quality. Maybe its got to do with bandwidth that BT provides.
Lastly, I may be wrong, but Radio roms are only used for GSM radio. Its got nothing to do with BT.
Gurus, please correct me if I am wrong anywhere.
Sid

I'm using faria ROM Real Thing and using Oakley OROKR as my bluetooth stereo. But I have unusual problem. When I listen MP3 from pocket music 4.3.4 my OROKR produced a lag sound. Sometimes the sound was disapeared and suddenly back to normal again (with lag of course). I have try my OROKR with my PALM Treo 650 using A2DP s/w it's produced same quality like my MDA. Is this happen cause the registry setting or my OROKR problem? Help me?
PS: If I used OROKR to call it's 100% normal

For what it's worth, i have tested my plantronics pulsar 590a (bt ver2) with other htc devices with bluetooth ver 2 and audio was excellent. the wizard only has bt ver 1.2 and that is maybe where sound quality is lost. just a thought...

did you buy the headphones on ebay? Got mine on ebay and I was very disappointed with the sound quality. i checked online and, for my surprised, i discovered that what I got from ebay was a cheap fake. I bought a new set from sony shop and voila, they work perfect. Sound is amazing..with the SE k800i i am using from time to time. Couldnt get them to worjk with my xda2i tho

I have latest V1 rom from Lt.Cmdr.Ivan - BT headset is Philips SHB7102 (works great with my Wizard and SEk800i). I did exacetely what U have asked for (but i have left jointstereo=0) and nothing happend. It sounds like 2s of music folowed by 15s of silence, then again 2s of music and 15s of silence. I messed with bitpool walues and couldn't find any working set. I'm afraid that's something wrong with max BT speed and not with A2DP implementation. I had BT speed switch app when I used broadcom BT stack and A2DP works great. Unfotunatelly normal mono BT headset doesnt work at all with this BT stack so I'm back to original stack

I've found that with MS stack and my Jabra BT620s the best bitpool is 33... good quality and good range (no interruptions)... jointstereo must be 1 otherwise the sound uses too bandwidth...

I also have Ivan's V1 Rom and have an Itech Radio headset. I completed the changes that you suggested and found that A2DP works well it did before the changes too. I have noticed that the sound quality may be a little better and the pauses are slightly reduced.
The main problem I have found with A2DP with all AKU0.5 ROMS is the pairing of the headset. If you soft reset you phone while the headset is on, A2DP will be auto detected when the phone comes up. If you play music then the music starts and stops and the phone becomes unstable. The work around is to turn your headset off, soft reset the phone. When the phone comes up turn the headset on and activate A2dp by pressing the button on the phone. Music then plays fine.
The registry changes you suggested did not help the above problem. AKU0.5 ROMS all seem to have this A2DP autodetect error on reset at least with my headset. Very frustrating.

Hi Maniware,
Can you please further shed light in detail on the jointstereo?
Why jointstereo to be 1 or 0?
Thanks in advance!
KOR!

It goes well with joint stereo. Seems that it needs much less bandwidth. I've heard that jointstero=1 means that there is mono sound in effect.

"UseJointStereo"=dword:00000001 << mono
"UseJointStereo"=dword:00000002 << joint stereo
"UseJointStereo"=dword:00000000 << stereo
AFAIK

qtek 9000 - Logitech Mobile Bluetooth Headset
I'm not quite sure if my problem is right here - because i still have the original (last build) WM5 ROM (130.96 GER, Radio 1.09.00, ExtROM 1.30.185 GER).
I encounter statics while using the Logitech bluetooth headset, which is a mono one, making phone calls impossible due to stressed phone partners ... Only the person on the other end of the line encounters interruptions, me, as calling, not.
This is the main issue for me to update the ROM, and I'm trying to find out if any of your nice new ROMs will be of help.
Anyway, I haven't tried yet I'm afraid to destroy my device ...
thanx
Anna

my feedback:
device:
itech r35
Problems:
sound muted after 2 seconds of music.
audio players used:
audio manager
windows media player
i tried your advices, but not worked for me....
Sometimes it works when i put 70 (binary) on both Maxbitpool and bitpool...but on next device activation or reboot it just stop working...

A2DP and wireless
Just to be clear, my results are when I do not have wlan activated.
I changed UseJointStereo=dword:00000000.
Quality is good and it is definitely stereo.
Still have the auto detect problem. Interesting though, if I walk out of range for a while with the headset on, when I come back into range the A2dp is autodetect and the music starts playing through the headset again, quality is good. If I soft reset with the headset on and A2DP is autodetected, the headset is unusable.
If you do any of this with wlan on the quality is very poor with starts and stops.
Also noticed that audio manager does a better job with bluetooth than gsplayer, I think audio manager may have better caching.

Freezing
I think there's a problem with the latest core os files (AKU 0.7.0)... i havent' tried the MS BT stack, but with the Widcomm, using the bluetooth for anything more than 1 min, completely freezes the phone.
It does when listening music, transferring files, etc... if BT is idle, nothing happens (except than freezing the device when the Comm Manager gets confused and enables BT instead of gsm radio).
So it seems related to the core files.
Switching on and off, transferring data thru BT is a critical task and subject to lockups.
For the record, i used to use the BT A2DP and file transfer without ANY problem whatsoever in my old and horribly-underpowered HTC Tornado (omap850 @195mhz) so IT MUST WORK!

im using your latest rom and Motorola HT820 does not have a problem with it... even in the earlier roms you cooked... even tried it in indra's xoj version and darkforce's rom..

A2DP problems should go away, but then will come the freeze-after-1-min problems, like with my HP Stereo bluetooth headset

I've flash to your latest WM6 AKU 0.7 (WIFI Fix update 3) ROM just now. But sadly to say, the freezing thing still occurs after playing music with Audio Manager. It even freezes when watching videos using WMP. Usually around 1 minute it shall start freezing. FYI:

Samsung Omnia 7 choppy bluetooth playback

Hi All,
I would like to know if anyone is experiencing some problems with bluetooth headset choppy playback on Samsung Omnia 7 and/or WP7 in general.
My problem is that music is just unlistenable on my device using my Motorola S9 headset. Sound is cutting every 1 or 2 second !
Using wired headset or external speaker is ok.
Thanks for you answers/feedback
Regards,
Thomas

no problems with my jabra bt headset and my hd7. Just as smooth and loud as wired for audio (just wish videos were supported).
Have you tried deleting the profile and reconnecting?
Also might try another BT (maybe borrow someone's just to check), to help narrow it down to your BT or your phone.
My wife has problems with motorola BT's and android devices.

I use a bluetooth headset all the time and sound playback can cut out if the phone is too far away from the headset, or if arms / clothing get in the way of the signal. I tend to keep the phone in my breast pocket and that's OK. In the trouser pocket, it's terrible.
So try putting the phone nearer to your headset and see if that makes any difference.
Bluetooth radio is very, very low power, and it's not surprising the signal can get cut off by objects that are in the way. Distance is a big factor too. I guess some headsets are better at receiving a reduced signal than others.

Thanks for your answers !
No matter what I try, it doesn't work... But I remember having tried my headset in the first times I got my device and it was working, I am sure ....
I am going to wait until nodo is out and we'll see if it solve the problem.
Thanks
Thomas

I have the nodo update and experience the same problem as you--choppy bluetooth playback with interruptions every 2nd second or so. The worst thing is that playback was perfectly fine before the update, and if i roll back to previous version playback is fine again. The choppy playback seems to have been introduced by nodo. Has anyone else experieced the same?
My phone is:
OS version: 7.0.7390.0
Firmware revision number: 2424.11.1.1
Hardware revision number: 3.15.0.4
Radio software version: 2424.11.1.1
Radio hardware version: 0.0.0.800
Bootloader version: 4.1.0.5
Chip SOC version: 0.36.2.0
It might be work noting that the phone had copy paste functionality on delivery (I got the phone a couple of weeks ago). The version number was pre nodo, but more recent than the vast majority of Omnia 7's out there.

Happens on my Omnia 7 as well. Solution? Disabled wireless.

Does not seem to do the trick for me. Tried to disable data, wireless and GPS. Still the same chopping playback. Do you have the same versions as I have?

No, I don't have the nodo update and the only difference aside from that is the radio software.
2424.10.10.6

I had the same problem with my BT headset after the NODO update.
Solution (at least for me):
using Registry Editor:
HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Bluetooth/AudioGateway
Set SupportCLI from 0 to 1
My BT headset works like charm again
I have no idea why MS changed that value in the update...

Thanks for your answer, guess I'll have to find out how to modify registry on Windows Phone 7.

Neither have I. Seems like they are developing procedures on how to release updates to the new platform. Seems like things can get a bit complicated with OEMs in the loop. Quite impressed anyhow by how smooth the update was either way, quite an accievement to deliver updates to all windows phones.

This is concerning to me, as a Samsung Focus owner on AT&T. I've been awaiting the NoDo update for the much-needed Marketplace bug fix(es) and application launch performance improvements. But the Bluetooth implementation and operation works perfectly for me now, and I really hope Samsung/Microsoft didn't botch it with this update on the Focus too. I usually plug my phone into a cassette adapter in my car (using the 3.5mm headphone jack) and wear my Bluetooth headset for calls. Calls are directed through Bluetooth, while Zune playback goes through the wired headphone jack. It's perfect and I really hope they don't change anything because unlike Windows Mobile, there are no advanced settings to fix or change this behavior. I shouldn't have to use a XAP or registry editor to fix it either.
