Comment 2 for bug 258630

I've found a workaround by another distribution-user (in German):

http://wiki.archlinux.de/?title=Soundkarte:_hda-intel

Just do the following if you own an Latitude D430 (and maybe other Latitudes):

1. create/edit file "/etc/modprobe.d/sound" and change the content to:

      options snd-hda-intel model=dell-m22 enable=1 index=0
      alias snd-card-0 snd-hda-intel
      alias sound-slot-0 snd-hda-intel

2. reboot
