I’ve got a bit further! Did clean install as just an Airplay (tested worked), then installed DLNA (tested worked), then installed Spotify (tested worked). The install for Bluetooth is not working as well. I installed it, scanned and connected the google home (name Deck Speaker in the log) just fine. But when I try to press „start Bluetooth-Speaker“ under Stream directy to Max2Play Soundcard, the Msg is „Trying to launch…Not successful“ and the „Click here to show detailed information“ does nothing. I also tried from Google Home buy making the M2P-Blutooth connection the Default Music Player output but there is no sound when it plays. There is not much in the Log:
