My old work PC used to work in 5.1 in Vegas gloriously. But I recently got a new work PC running 64-bit Windows 7. I'm having a lot of difficulty getting 5.1 audio work via the optical out in Vegas Pro 9.0d.
Specifics:
My amplifier / receiver accepts Pro Logic, Dolby Digital and DTS via the optical input. It also accepts Pro Logic, but not sure if it's 5.1.
The PC's motherboard's optical out only outputs Pro Logic. It doesn't encode Dolby Digital.
To fix the above issue, I have a Creative X-Fi Titanium Fatal1ty Pro sound card, that supports Dolby Digital Live and DTS, but this requires "exclusive control" of the audio output, and starts the CTAudSvc.exe (Creative Audio Service).
HOWEVER, when CTAudSvc.exe is running, the receiver reports it's receiving Dolby Digital - but no application can actually play any sound! When I try to audit Vegas in 5.1 Surround, I get an error message, "Audio device already in use". So does the Sounds control panel.
When I kill CTAudSvc.exe, the Windows control panel can test-play all 5.1 speakers individually, but Vegas doesn't work in Surround (because it doesn't encode Dolby Digital Live nor works with Pro Logic 5.1?).
Is this a Windows 7 64-bit issue, ie lack of proper drivers for the Sound Blaster, or something else?
Already tried updating to latest Creative drivers, and also installed the "Product Identification Module Update" and the "Dolby Digital Live Pack", no avail.
So... does anyone know any optical out Dolby Digital (or DTS) 5.1 sound cards that actually, reliably work on Windows 7 64-bit?
Thanks!
