I connected my MacBook to the “USB Audio In” port on my RS250A and switched INPUT to USB IN. The audio only plays for about 5 seconds, then disconnects. To get audio again, I have to select another INPUT (like INTERNAL or OPT IN), then select USB IN, and it plays for about 5 seconds before disconnecting.
Do I need to do something else to get this to work?
I want to use Room EQ Wizard (REW) to get measurements for my subs and loudspeakers. This is why I prefer USB instead of AirPlay. The USB sound cuts out whether using REW or playing music from my MacBook.
