Sound disappeared, how come?

[TK]

I've been using the built-in sound on my MSI (K7T Pro 2) 6330 motherboard for quite some time with no problems. Had a problem getting 2 drives to work on the same IDE cable, and installed Via 4 in 1 drivers, and immediately had no sound on re-boot. Just prior to the update, I did a partition copy to another drive, and on booting from it - I STILL had no sound??? Swapped speakers, massaged the bios settup, and still have no sound!??

Assuming, for the moment, that the motherboard is not bad, any ideas how to attack this?

If you were fiddling with the BIOS, make sure the OnBoard Sound did not get Disabled.

If you were unplugging cables from the back of the PC, make sure the speakers are plugged into the correct hole, and not into the microphone hole, etc.
