Indeed, that seems to be the problem. I was always under the
(uninformed) impression that SBC was lossless, but I just tried
re-encoding an MP3 to SBC and playing that SBC with sbcenc and sbcdec,
and the exact same audio artifacts are showing themselves when I play
back to my normal speaker system as through the headphones.

So, at least it's not a hardware or BT stack problem. Is this an
inherent problem in SBC, or is there a way to tune the encoder to
compensate? Is it possibly so that a better encoder could be written
altogether?
