Thanks for the suggestion, no luck. For now, I just rolled back 3 updates and it works fine. I guess I'm going to stay there for a while as it's waaaaaay too frustrating. :)

What are you trying to accomplish? I can't think of a scenario where selecting all and exporting would be the preferred procedure.

Is this not the preffered way to do a mixdown in/from Sonar..?

Because of "audio" in the title I thought the OP was talking about exporting clips. I was going to refer to the export option for clips as a better way to do it.

What about your Audio devise ? / soundcard ?
 

Up to date. Just for kicks I tried another device, same problem.

I was actually asking what kind of Devise.
Don't rule out Windows update as your issue. Its critical you at least/ at minimum have the C++ redistributable.
I would check again and make sure you don't have any updates in cue. Sibelius and Wavepad are not updated every month like Sonar is. This is why it is critical to grab the latest C++

Did an uninstall/clean install. I'm back, baby, I'm back. 

That was a strange scenario.  Well, we are happy to hear that all is working well for you again.

.........and we're back.  Problem is still there. Don't know why it worked for a bit and crept back, but it did. It's now crashing every time I even click the "export audio" button...
