Onboard Soundcard Issues

I have an ASUS P4V533-MX motherboard which uses an onboard "VIA AC'97 Enhanced Audio Controller" soundcard.

I used to have an old Create PCI soundcard, but I removed it as I no longer required the old style joystick port it had, which was the only reason I had it installed.

Now I'm using my onboard sound card, I am having trouble with it in fs2004. When I am in spot view and I rotate my vewing angle, it sometimes lags (jumps) for a few seconds. When this happens, so does my sound (ie. it goes silet for the second the camera is still)

I think I would be able to fix this via a driver upgrade or something- can anyone tell me how to do this?

Cheers,
Trolly

Have you try to set FS quality sound to Low?

Dunno how to solve your issue (sorry ) but a 5.1 soundcard and speakers are as little as £40, thought about investing?
