Kernel doesn't seem to be right. Sound was working, but now no sound.

Ran alsa-info.sh, returned:

Then checked the hardware with

which returned

Not sure what I need to do to get sound again. In 10.04, my system worked after using newer Alsa drivers, which seem to be in the current kernel now. But, I'm not sure how I've wonked things.

My machine is an Acer Aspire 7736z w/ HDA Intel (maybe Realtek 888--that's what it used to show)

Can someone help?
