Default Geforce GS250 Causing Sound Problems Ubuntu

Hey all. I recently changed my graphics card to the Geforce GTS250 and am running in to some problems with my sound.

When the graphics card drivers are not installed, sound is fine. However, as soon as I install either the official Nvidia drivers or the Ubuntu repository drivers, I lose all sound. The system still seems to find my sound card (integrated Intel), the sound card is selected as the device to be used for sound, nothing is muted, volume levels are all up, and equalizers seem to show that sound is being played. Yet, as soon as the Nvidia drivers load up, I have no sound.

Any thoughts?

I don't believe the particular video card you have has any form of audio device on-board, and so should not be interfering with audio in any way.

I notice the following in your kernel log files. Perhaps this correlates with when you lose sound?

Code:
hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj.
I'd suggest seeking help in some Ubuntu-specific forum. or an ALSA support forum. Even though your description implies that the NVIDIA driver is causing this issue, I suspect the root-cause is something in the ALSA driver for your HW, or your audio HW itself.
