Sound card no longer recognized

[Krampusz]

Hi,

I've spent the last few hours searching this forum for an answer, but nothing I found worked. I found many similar questions, so this might seem a duplicate, but as far as I can tell, it is not.

I have a relatively new Dell Latitude E6320, running Kubuntu 11.04 Natty Narwhal

I had the sound working fine using Pulse. Then at some point it all went away. My guess is that when I installed some new packages, some settings were reset and now my system does not see my sound card.

Here is what I can generate:

lspci -vv

gives

and

kmix only lists "Dummy Output"

alsamixer shows an empty window.

I'm even thinking about reinstalling my system, but is there a way to do that and not to install the last few packages I installed. Or in other words, any advice on what packages I should NOT reinstall? If PULSE is running and works, do I need anything ALSA related at all?

Thank you very much for any kind of help!!!

Re: Sound card no longer recognized

Do you have an 11.04 Live CD that you could boot? If so, and if sound works, you could do lsmod and look at the sound driver, for example.

Also, there is a list of options for the snd-hda-intel driver -- I'm not sure about the Dell Latitude. Click the "top 20 FAQs" in my signature, find the one on audio issues, and chase the links there.

Re: Sound card no longer recognized

Thanks for the advice!! So far so good.

The sound does work with the Live CD and I've got the output of lsmod. I made stab at what I need to do, but it has not worked. More specifically I tried adding the line
options snd-hda-intel model=dell_laptop enable=yes
(and the same with just model=dell, model=auto, model=generic, with or without the enable=yes option)

I'm afraid I need some help in interpreting the output of lsmod. It is attached.

Any further (and already given) advice is highly appreciated!!
