AV48 drops audio switching from tv setup as optical input to any other source.
Setup: AV48 with vs-2 expander. Vs2 hdmi out to tv, tv optical to AV48 optical input. cable box hdmi to expander box with analog audio to AV48. Tv selected as optical source in system menu.
I can switch to Tv to use the smart tv apps with audio and video successfully.
However, when I switch back to any other source, including AV48 internal sources such as dvd or radio, the audio drops out, seems to stay on optical input.
I’ve tried several system settings changes such as anynet/hdmi-cec, retain video when switching audio sources, etc. this just seems to be a bug unless I didn’t find the magic option settings combination.
I have only been able to recover by power cycling all parts of the system (AV48, cable box, tv). That’s not an acceptable solution for an expensive system like this.
I’m also very disappointed the vs2 expander box doesn’t at least support pass through for hdmi audio, but that’s another topic like hdmi-arc...
