Bug Description
Each time I install a kernel update (or more likely the accompanying module update), my sound stops working - nothing plays out of the speakers and the sound config applet does not recognize any devices. I have to recompile alsa-source with module-assistant in order to reenable sound. Are there some changes in the alsa source that need to be merged into the module package? This is on a dell Vostro 1500 with an Intel HDA card (also described in the bios as Sigmatel 9205)

I ran into the exact same experience this morning when I received the kernel update to 2.6.22-12-generic. I also have an HDA Intel sound card (my card is presented as "Realtek High Definition Audio" in Windows Vista) but ALSA mixer usually says card="hda intel" and chipset="realtek ALC268".
To fix my sound I used this command "sudo apt-get --reinstall install libasound2 libasound2-dev" and then rebooting.
I suspect, it would be possible to make some kind of relatively simple change to the standard Gutsy configuration to prevent this from happening. Such a change might also fix the fact that sound is broken by default on HDA Intel / Realtek cards.
