High Pitched stuttery Quicktime Audio?

[tefman]

Anyone have this problem?

I'm on an i7 macbook pro... trying out the demo of GVJ
osx 10.6.4

Movies are Qtime Animation DV or MP4

Any Thoughts?

Well, a similar problem indeed occurs on my MacBookPro 6.2 / i7.

I've spent hours investigating/debug the problem to finally discover that a third party application that was using a virtual audio device (in my case the official iPhone Simulator application) that as soon as outputting some audio messes up GrandVJ audio output behavior. In my case, GrandVJ works as expected if I don't start the faulty application.

I've also noticed my system as a similar "Adobe Media Encoder" virtual device installed, but it doesn't seem to interfere with GrandVJ.

Update:

I've just discover that you can inspect installed virtual audio devices by starting "/Applications/Utilities/Audio Midi Setup.app" on your Mac.

So if all virtual audio devices are turned off does G VJ settle down Qtime Audio?

BTW it does not seem to be a codec issue. DV. mp4 and Qtime Animation codec all do the same thing.

Funny I've got X-code too. as well as Adobe Master suite.
