The guys over at xda-developers.com did it again and found a way to enable A2DP on Windows Mobile AKU 2 updated devices, even if your operator left out the A2DP and AVRC Bluetooth stereo profile out!
Sure, this is neither a supported tweak nor an official way to get A2DP enabled on your Windows Mobile 5 device and therefore everything you do, you do on your own.
Basically, the original way "sas90850" and "kyunga" posted contains 4 files (3 DLLs and one CAB file) and a Registry modification you have to do on your own.
However, "Khuanchai" packed everything in one CAB file which installs all DLLs and the CAB on your device and modifies the Registry on its own, no need to modify it yourself anymore.
I've tested the "all-inclusive" CAB on my i-mate SP5 Windows Mobile Smartphone (even if the CAB was designed for Windows Mobile 5 Pocket PCs) but since the core of both Windows Mobile 5 devices is the same, it also works on Smartphones:
I haven't tested it yet with my non-A2DP enabled Windows Mobile Pocket PCs but will let you know later. However, since the original all-inclusive CAB file was developed for the Dopod 818Pro it should work, as it is also confirmed on xda-developers.com.
Again, everything you do on your Windows Mobile device, you do on your own but from my perspective I can say I got working everything: Bluetooth stereo from my Windows Media Player (A2DP) and Windows Media Player remote control with play, pause and next/previous track (AVRC).
Please not, you have to be a registered member of the xda-developers.com forum to download any files from over there.
