Graphics card driver/audio clash...

Hi. Any help you have to offer would be greatly appreciated.

So I've recently built my own computer and everything's gone very well (to my surprise) apart from one thing.
I'm having problems between my graphics card (Nvidia GeForce 9600GT 1GB) which is currently on an HDMI connection to my monitor, and my fairly cheap sound card (Genius Sound Maker v1.2).
I installed the sound card's drivers first, and had sound but just after installing the graphics card drivers, the sound
dissapeared.
I decided to uninstall the graphics card drivers and the sound came flooding back, so something in the graphics card drivers is ruling out my
sound capabilities.
I've checked to see if there's a hardware conflict and there isn't, everything is working fine according to device manager.
I'm pretty unsure of what to do, and it's fairly annoying because i can either play games with sound and very poor graphics or
good graphics and no sound.
Life's full of little dissapointments i guess.

I should also probably mention I'm using Windows XP Home, no service pack 1 or 2 yet...

Ah. Yes that would have probably worked, but I did eventually resolve my problem, not through the way I would have liked though.
I changed the connection between my pc and monitor to DVI instead of HDMI and it worked. Would have liked to have used HDMI but I guess there's not too much of a difference.
