Bug Description
I have a new N5110 running Oneiric (stock) but my soundcard doesn't output any sound through either headphones or internal speakers, even through aplay, although I'm mainly testing it by playing a continuous playlist of gnome sounds through Banshee while I was exploring alsamixer.
I've tried upgrading the linux-alsa-modules to the version matching my kernel, but makes no difference on a reboot.
I have two sound cards as reported below, but it doesn't seem to make any difference which I select, there's still no sound.

I found this terminal log of a force reload surprising. I experienced it after trying to specify a different model option in /etc/modprobe. d/alsa- base.conf but also found the same after reverting to the original file.
If the failure of the midi module causes all the modules to fail to load, that could explain something perhaps?
