Here an update: After some time – music playing via LMS or not – the Echo Dot’s sound wont get through (squeezelite paused) while being still connected. After reconnecting „disconnect speaker…connect..“ it works well again like playing via LMS, pause, asking Alexa, playing via LMS again.
Remark: Config is directly play to Max2Play, not via LMS.
I’m not sure who’s responsible yet – Echo Dot or the bluetooth setup.
Would you recommend to try to connect/play via LMS?
