Disable HDMI sound output when using optical (TOSLINK) output on AppleTV I have Apple TV and have both HDMI and TOSLINK (optical) port connected. But the problem is that when i turn on the video via Apple TV I have double sound from the sound - from the TV set connected via HDMI and the sound system connected via TOSLINK. The later is deleyed due to the fact that TOSLINK is coverted RCA.  This makes me turn off sound in the TV set.

Is there a way to not transmit sound via HDMI in Apple TV if it is anyway transmited to TOSLINK?
You could always use an HDMI cable that doesn't carry sound, not too expensive these days.
