If you have a Zoom Q2n-4K camera and it does not output audio to your Roland switcher over HDMI, this guide walks you through the camera setting you need to change.

 

On the camera, go to the recording screen and look at the right side of the LCD screen. There are 3 options. Press the Audio button until the middle option, 48k 24bit, is highlighted green.

Roland switchers have a 48 kHz 24-bit sampling rate for audio. You should now hear audio on the Roland switcher's HDMI input.
