Hi

I'm having a lot of trouble with my FF400 using Vegas in 5.1 - whenever I switch apps to anything (not necesarily an audio app that might try and steal the audio driver), I lose audio playback in Vegas completely.  Sometimes I can make it reappear by switching driver types from Asio to windows driver then back again, or by changing bit depth settings to 16 bit then back to 24.  It's incredibly frustrating.  Does anyone have any idea what I might do to remedy this situation?

Thanks
