nmalinoskiSetting TX mode to DVI should disable digital audio output.
Changing TX mode to DVI causes my receiver to fall back to optical audio as I hoped; unfortunately, this setting is somewhat buried in the menu; and, as megari noted, the mute button is already mapped to something else.
I suppose it’d be too complicated to try to detect whether there’s an audio signal (versus simply detecting whether a cable is connected, which is easy); might just be simpler to ask for support in the firmware to have the mute button toggle the audio, or wait for a TOSLINK-enabled OSSC (if one should ever arrive).
