>> Your log indicates your HDA codec is a "Conexant ID 506e" - the Conexant driver does not yet support this codec, so the driver falls back to a generic driver. I intend to make a new attempt later this week to add a quirk for that particular chip. If you, in the meantime, could point me to a bug in Launchpad (filed with the "ubuntu-bug audio" command), that would be helpful, as that would include valuable codec info. Thanks!

Ok, alsa info works just as well, see wiki.ubuntu.com/Audio/AlsaInfo

I just sent an entry for 506e upstream to alsa-devel. You might need a 
second quirk on top of that, just like I added for the Dell machines,

I can't tell without having alsa-info but you might to be helped by my 
input mixer rewrite, which I'm still trying to get tested and committed 
into PulseAudio.
