consumes A LOT of CPU. Need alos to change the command line to set the
sample rate (-r) to a fixed value (BT) but accept igher (-Z) from LMS
and enable resampling (-R)
-R -Z 96000 -r \"44100-44100\" or similar
Some instabilities to tackle. BT Ring buffer were taken out. DAC is
crashing with stack overflow. So does A2DP after playing for a little
while. This needs to be investigated.
