Did you try disabling your MoBo's ATI video chipset in your BIOS when you are using NVIDIA?
Is there an interrupt conflict? The kernel boot options noapic and / or nolapic sometimes help here.

noapic option throws loads of errors on boot-up and X won't load.
I've found some info in /var/log/messages which only appears when using the nvidia driver (i.e. I have no sound):

dmesg says:

I have to say I'm getting pissed off now. I've been trying to get my HTPC working with Ubuntu for SIX MONTHS. It's one thing after another. I've already had to buy a new motherboard because the ATI card wouldn't work in it. Then the ATI card gave huge overscan so I bought an NVIDIA card. Now the nvidia driver disables my sound for no reason whatsoever and the nv driver fails to render quickly enough.
