Yamaha YMF Surround Support

[Rhizome]

As I said in another thread, I've got a Yamaha YMF744B-V, but I'm stuck when it comes to the correct drivers for it. At the moment I have Yamaha's own XG drivers installed, but since I've had to send back my Audigy 2 ZS I want to use this card.

It has the following ports:

Optical out
Front out
Rear out
Mic in
Line in

But the normal Yamaha drivers don't support the surround sound (and it removes all 3D Hardware Audio support from the card, so I have no surround in games such as UT2004). Reason I want to use the Yamaha instead of my onboard is because the onboard gives off a high pitched noise which sounds awful. The onboard also uses 2x more CPU than the Yamaha (2.8% for the onboard in 2d audio, 1.4% for the Yamaha).

Does anyone know what drivers I should try? I know I can get more power from this card.

No matter. Found out it's an AOpen AW744 Pro (different revision though) so I've got the correct driver. Too bad 4 channel doesn't work under Windows 2000
