Trying to improove A2DP sound quality

[shadowmite]

While this depends greatly on the device, the best setup is to not use joint stereo (that disables true stereo, while it was needed on wm5 old rom devices, it's not needed for newer roms on wm6 and hurts the overall quality), and bitpool set to none (delete the keys). With bitpool to none, the device will automatically determine the best settings to use.

Regardless, the 6800's bluetooth is a little flakey but I get great results on my S9's as well.
