For some reason, computer audio just stopped coming through my FM9. I am using the FM9 as my audio interface and monitoring through the FM9 headphone jack. It had been working fine up until tonight. I am hooked up through USB & have always been able to play along with You Tube backing tracks. Apple Music or anything else I play from my computer is not coming through at all. I rebooted the FM9, rebooted my Mac Studio, and checked for any possible settings that may have changed, even though I haven't changed anything. I hear my guitar fine. Does anyone know what is up?
