The speakers (and plugged earphones) on my HP Touchsmart 300 work fine. However, the mic doesn't work at all, neither the internal one nor a plugged one. In Windows the mic works as expected, but naturally it's very annoying to have to switch to Windows just for the sake of using Skype... I think this may be a bug in ALSA but I'm not 100% sure.
I'm using ALSA v1.0.24.2 and ubuntu natty with kernel 2.6.38-10-generic-pae. The last line of my /etc/modprobe.d/alsa-base.conf file is:
options snd-hda-intel model=touchsmart
although I have also tried unsuccessfully with:
options snd-hda-intel model=mobile
options snd-hda-intel model=laptop position_fix=1 enable=yes
options snd-hda-intel enable_msi=1
options snd-hda-intel model=auto position_fix=1 enable=yes
