Audio not sounding

I have suddenly lost audio from Wavelab on my MacBook. I’ve checked preferences, and audio is selected properly, going to my headset. And I get sound normally on both iTunes and Cubase. But the sound from my files in Wavelab don’t sound. Is there somewhere in the program where you can check the audio preferences or figure out where it’s not connected?

In Wavelab 7, it’s in the Options menu, Audio Streaming Settings. It shows the Audio Device and Playback Output Channels.

I have had the same problem. Gonna follow the thread for updates.
