I now upgraded alsa,PA,bluez from your repo. What catches my eye is this message in the logs:
bluetoothd: profiles/audio/a2dp.c:a2dp_select_capabilities() Unable to select SEP
systemctl restart bluetooth.service does now help getting a2dp work.
I wrote a little script with sudo to do this as $USER. A workaround I can live with....
