Reply To: Does the OSSC add audio to HDMI when audio input is disconnected?

Setting 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).
