Reply To: USB Audio Mute is ON (in red letters on the upper right of the display)

I get this sometimes.

To fix it in Ableton Live, I change the audio driver to select the Eventide, then it goes away, and then I can select my RME. (I route to H9000 with ADAT.

I have woodblock as my audio clock.

Basically the H9000 needs to know that USB clock matches its clock and then it will work.  The USB is controlled by the computer, so it has to set the clock for USB.
