Maybe I am missing something, but as far as I know, the analog audio output is always enabled on the FIOS boxes, but I cannot get any audio through the Mac Desktop app and my M1.
I have the M1 connected via Analog RCA cables coming out of the FIOS box. The connection from the FIOS to TV is HDMI. Getting great Video, but nothing on the audio side. Tried 2 sets of cables.
Running desktop Mac Client.
