[MDA III, XDA III, PDA2k, 9090 Software Upgrading] spkr4thdd:
OK, having compared the registry files of TuMa 1.4 and the new Helmi 2.3 ROM the only major differences with regards to A2DP are as follows...

In TuMa 1.4 we have the following...

[HKEY_LOCAL_MACHINE\Drivers\Active\48] The number is irrelevant really

"Hnd"=dword:0051dcc0

"Name"="WAV8:"

"Key"="Drivers\\BuiltIn\\BtA2dpSnd"

"BusParent"=dword:00032a90

"InterfaceType"=dword:00000000

"BusName"="BuiltInPhase1_0_44_0"

which doesn't appear at all in the Helmi ROM.

And we also have the following in TuMa 1.4 (Once the device is paired)

[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\Device\000d3c32adb3\Services\0000111e-0000-1000-8000-00805f9b34fb]

As you will see from the above, the A2DP driver doesn't seem to be active within the Helmi ROM for some reason, although its entries within the HKLM\Drivers\BuiltIn\ is identical in both ROM's... in addition, probably because the driver isn't active, a channel isn't allocated to the A2DP profile...

I've a feeling that this may hold the key!

@Helmi, would you believe that I can't find the sbc.dll from TuMa's ROM!! I'll flash it again and get it to you as soon as, but it may not be necessary if we can activate the BtA2dpSnd driver in yours... I'm off to try an manually add the missing entry, and then I'll try again... will update soon ;)

EDIT : Nope, can't add to the active drivers list... it's volatile (doh!), so something is preventing the BtA2dpSnd.dll from starting up...
