Sound absence again. Even after alsa update.....

I don't see the codec listed. To get this info please run the following in a terminal:
$ cat /proc/asound/card*/codec* | grep Codec

Looking at the entry you mentioned, can you verify - if you run 'lspci -nnk' in a terminal you should see this sound card:
Multimedia audio controller [0401]: Cirrus Logic CS 4614/22/24/30 [CrystalClear SoundFusion Audio Accelerator] [1013:6003] (rev 01)

Please include the indented lines underneath which include the modules loaded for that card.

Also please take a look and update the following wiki page no matter the end result of your experience. Thank you.
