Hi @Finnlubbert 

Your Sonos Playbar does not support the playback of Multichannel LPCM audio, if that is what you are trying to play - only stereo PCM (which isn’t generally referred to as LPCM). Only Arc and Beam (Gen 2) support LPCM.

As a result, I am not entirely sure what it is that you are reporting - if it worked before the update, it wasn’t Multichannel LPCM, and combine that with you having a Playbar rather than an Arc, and you are off-topic for this thread. I recommend you start a thread of your own.

I hope this helps.
