Hi Folks,
 
I recently upgraded from my Babyface to a Fireface UFX. Now, whenever I use another audio program (in this case iZotope's RX3) while Sonar is running and then go back to Sonar, I get the following error message:
 
Unable to open audio playback device. Device may not support the current project's audio format or may be in use.
 
Reasons this confuses me:
 
1. I never had this issue with my Babyface.
2. I haven't changed bit depth/sample rate settings.
3. I've got the "Share Devices With Other Programs" option checked.
4. I have RX3 assigned to different hardware Ins/Outs than Sonar.
 
Any thoughts as to what I can do to rectify this?
 
Thanks,
Ben

Wrong was I. The file I'd opened in RX3 had a sample rate of 44.1, whereas my Sonar project was 48, so the audio format had changed.
