I never built libreelec by myself. I'll try it, but this will probably take a while! Thx! -- Josef Wolf j...@raven.inka.de

Ah! Thanks for the hint, Georg! This works (as far as PA is concerned!) Turns out that I mis-interpreted the cause of the problem. The real problem seems to lie withhin the BT stack: the BT-speaker will not reconnect automatically when libreelec is rebooted. Adding systemctl start bluetooth (sleep 1; bluetoothctl connect "A4:77:58:02:93:FB") & to the startup script solved the problem. Thanks! But there are some noticeable sync-problems (one stream seems to be somewhat delayed). Is this expected? I thought module-combine-sink would try to syncronize? There are some sync issues with the combine sink that should be fixed in current master. Do you have a chance to test it? https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/tree/master
