Hello,

I talked to Jeff about this and he seems to think this is an issue with Cakewalk Sonar so I posted this on the Sonar forums. I am posting it here in hopes that someone here using Sonar and Win7 64bit and a Multiface II PCI-e might shed some light on this.

"Unable to open audio playback device. Device may not support the current project's audio format or may be in use."
 
 
1. I open Sonar and I can play a project fine. Close Sonar.
2. Play a wav or mp3 on Windows Media Player fine. Close Windows Media Player.
3. Open Sonar and push play and the above message appears. Close Sonar.
4. Open Sonar again and the project plays fine.
 
Anyone know why this happens? Kinda of a pain in the ass.
 
I am using the ASIO driver for my RME Multiface II PCI-e card.
Win7 64 and Sonar 8.5 64 bit.
 
Global Options /Audio Data /File bit depths are
Record 24
Render 64
Import Original
 
Options /Audio Options /Sampling Rate is 96000
 
Thanks!
