Noob here. My sound was working perfectly until yesterday. I think the updates from updates manager screwed it up. I have a dell XPS 15 running Ubuntu 11.04
And my problem is that in the sound properties it only shows the hardware for HDMI out, which means that my headphones jack/ speaker and even the internal mic don't work
I don't remember what the other hardware was.
I tried some fixes that I saw around like inserting an option line in the /etc/modprobe.d/alsa-base.conf and reloading alsa but that didn't help

You have the hdmi digital stereo output as your profile, try selecting analog stereo duplex. If no options other than hdmi appear in profiles post the terminal output of this command:

aplay -l

so i just rebooted my computer since I posted and now the HDMI out is missing too so now the aplay -l output is blank

aplay -l

Something's borked. Run this command in a terminal:

wget http://www.alsa-project.org/alsa-info.sh -O alsa-info.sh && bash alsa-info.sh
Choose the upload option and provide a link for the output.

Before we go any further, edit alsa-base.conf to remove the model switch you added, reboot and run the script again.


gksudo gedit /etc/modprobe.d/alsa-base.conf
Remove this line:

options snd-hda-intel model=generic

Hey so I decided to boot in the windows to see if it was working there. But it wasn't so I think it might be a bigger hardware issue than just ubuntu. Thanks for your help. I'll mark this as solved as of now and try to figure it out with dell. Thanks again!

Remove the edit to alsa-base.conf, specifically the line beginning with "options snd-hda-intel". Next follow the link in my sig to upgrade alsa.
