Fact:
Microsoft's A2DP implementation in WM5 is incompatible with certain headsets.
Certain headsets, such as many Nokia and Logitech ones, sound incredible (as good as wired headphones), whereas others, like i.tech or Jabra, don't.
This has been a subject of much confusion to WM enthusiasts, since these headsets sound great when paired with other devices, however when used with a WM device, a high pitched ringing/hissing and slight distortion is heard when certain frequencies of sound are played.

Some Pocket PC users have temporarily solved their problem by porting the Widcomm Bluetooth stack over from the Dell Axim series, however it is generally buggy and not available for all devices.

Fact:
Windows Mobile 6 Beta was released, and had even worse A2DP than WM5
When the beta/demo roms starting floating around, many of us who experience the problem had a glimpse of hope that maybe it would be fixed.
But alas, the A2DP support had many people re-flashing back to WM5. It was even worse.

Fact:
THE FINAL RELEASE OF WM6 SUPPOSEDLY FIXED THE QUALITY BUGS OF A2DP!
There is a write up about this here:

Basically, the new devices shipping with WM6 seem to be more compatible with a wider variety of headsets than its predecessors.
Headsets with the static, popping, hissing, etc... finally sound good even with the Microsoft bluetooth stack.
Some of the new cooked Roms are starting to use this new A2DP support as well.

Problem:
WM5 still sounds bad with A2DP!
Those of us who don't have WM6 upgrades available, or don't want cooked roms or beta versions, are stuck with the poor A2DP of WM5.

Solution:
SOMEONE NEEDS TO MAKE A NEW A2DP PATCH using the WM6 drivers!
Remember when someone first made the A2DP support for Tornado available in WM5? If your device didn't have A2DP to begin with, all you needed was AKU2, and this patch would install the signed drivers and make the appropiate registry edits and like magic we all had A2DP (albeit crummy with some headsets)!

Over time, other patches were made, some using AKU 3.5 and other later releases that promised the possibility of better sound. But all of them failed.

What we need now, is for someone who has an official WM6 device (or someone who has access to a decent cooked ROM with the new A2DP support) to help make a NEW patch for those of us who need it!

Anyone out there willing to help?
