Thanks for spotting this!

Some problems remains:
- the sound is much "choppier" than with a2play
I suspect this line from a2dpd output:
setscheduler returns -1 (errno=3D1:Operation not permitted)

must I run a2dpd as root?

- I only get sound in 1 earpiece, the sound is very soft in the other one.
