Audio out to TV?

If I hook the ETC up to a TV via HDMI, will the audio be played out of the TV?

No, the audio input is not passed through HDMI.

Hello, oweno. I have a question related to this.

If audio input is not passed to HDMI, how can i hear the audio input?
I’m working on mine(ETC), after i hooked the mono audio input i couldn’t hear anything but just seeing the sound waves from the monitor. Any comment would be appreciated!

You will have to use a splitter or mixer to split to audio signal from the source to the ETC and an amp or speaker or TV or headphones.
