Audio Dropout After Export

Hey Gang,

I’m a Sonar orphan and a recent convert to Cubase. I’m having an issue and I wanted to see if anyone else has seen this. Sometimes when I export audio, I lose the connection with my audio interface. I’ll export the audio and go back to listen to the exported file in Cubase. The audio will export fine - I can see the meters moving on whichever track I’m listening to and the Main output, but my interface doesn’t register anything. The interface still shows up on the Mac and in Cubase Studio Setup. If I switch to the built-in audio in Studio Setup I can hear everything just fine through the Mac speakers or headphone jack. I’ll have to reboot the computer and the interface to get it back through the interface. I’m on a brand new MacBook Pro with the latest updates. I installed the latest update of Cubase last night but it’s still happening. I’m using a MOTU Ultralite AVB. Any ideas?
