Hi @Aco
Welcome to the Sonos Community!
Apologies for the delay.
The diagnostics you submitted were submitted while your controller device wasn’t connecting to your Sonos system, so there was no information about the Playbar there.
First, please make sure the Playbar is set to play TV audio.
Please try removing power from the TV for 30 seconds, then power back on. Sometimes the software (or part of it) on a TV can crash, rendering the audio output intermittent or non-existent.
Please also check the optical cable for kinks or damage - optical cables do not like kinks, and they can permanently damage them (even if you see the light from the other end of the cable, that doesn’t mean the signal is getting through cleanly).
If that doesn’t help then to isolate the source of the problem, I recommend you attach the TV’s end of the optical cable to another device, like a cable/satellite box, games console or even another TV. If you get audio from the Playbar, then the TV is the source of the problem.
If you don’t get audio from the Playbar regardless of what it’s connected to, please get in touch with our technical support team who will get some diagnostics from your system and check what’s happening.
