My StudioLive 16 is connected to my iMac (11.5 Big Sur w/ intel processor) via USB and I'm pulling audio from the Mac into my board via USB input on 31 and 32. Everything will work fine until I try to play a YouTube video or something similar and I get "If playback doesn't begin shortly, try restarting your device". Everything else is normal on the mixer and I still hear other channels of audio fine, but my iMac channels loose signal. I've tried unplugging and replugging in the USB cable, Checking the channel in my Mac's audio midi set-up, flipped through input sources on the mixer, and even tried deactivating hardware acceleration (although I'm using safari and I don't have the option). The only thing that works is a power cycle of the mixer, not even a power cycle of the computer with everything plugged in will fix it. Is this a computer issue or a mixer issue and does anyone experience the same or know what it could be?
