Comment 126 for bug 318942

Reporting again: I have sound in my HP mini 1033cl.

 I had tried Marambios' workaround <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/318942/comments/11>, but it failed. I just kept the lines added in [/etc/modprobe.d/alsa-base.conf] (without brackets, of course). Well, yesterday Ubuntu updated the kernel to 2.6.28-13-generic, and some reboots later (I don't know exactly why), I have sound in the built-in speakers. I have to say again: I kept the lines added in alsa-base.conf

# Finally, edit file alsa-base.conf

sudo gedit /etc/modprobe.d/alsa-base.conf

# Add these lines:
options snd-pcsp index=-2
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=dell-m4-1
options snd-hda-intel enable_msi=1

Maybe it will also work to someone else. Thank you all.
