When I change the output device it stays like that. So far I have tried restarting preferences, updating drivers for my interface, restarting my mac, updating OS version and even reinstalling all Logic but to no avail. nothing. I can use my interface and it's built-in with no problems in Pro Tools and Ableton. And the sound plays no problem from iTunes and Safari. The logic is the only thing that won't play audio. This seems like a big glitch when REINSTALL doesn't fix it. Does anyone have any ideas on how to fix this?
