I have a Dell 4700 that runs just fine on Ubuntu 10.10. On that machine, I have six accounts right now. Five of the six function properly with regards to sound. The sixth account (my wife's account) has no sound what so ever.

I've looked through the forums the best I could to find something similar to this issue, but nothing really came up.

I've been fighting this problem on and off for a month now, and am finally turning to the forums for some help.

I read through the Comprehensive Sound Problem Solution Guide, and followed the instructions to find the card, check the modprobe, alsamixer, etc., but there is still no sound. Can anyone help?

If there is some other information I can provide, please let me know.
