On a Thinkpad Edge 13 I had the problem that speakers played sound although headphones were plugged.
Using "model=olpc-xo-1_5" solved this problem. So it seems sensible to add this quirk. (Using other models, like ideabad did not fix it.)

I don't know whether adding this quirk is the right/complete solution to support sound on Thinkpad Edge. But at least it solves this annoying problem.
Well, Jerone Young already sent a quirk patch but he took model=ideapd. Could you guys check which one is really better?
Hi Jerone,
there are two different models of Thinkpad Edge (one with Intel CPU/chipset, one with AMD CPU/chipset). I tested on the AMD version but from
https://bugs.launchpad.net/ubuntu/+source/linux-backports-modules-2.6.32/+bu...
it seems that using model=olpc-xo-1_5 works for both versions of that Thinkpad.
I also tried ideapad -- because looking at the quirk table for cxt5066 there is this entry
SND_PCI_QUIRK(0x17aa, 0x21b2, "Thinkpad X100e", CXT5066_IDEAPAD),
and adding
SND_PCI_QUIRK(0x17aa, 0x21b3, "Thinkpad Edge", CXT5066_IDEAPAD),
seems to be conclusive.
But as I said that did not solve the problem of speakers still playing audio if headphones are plugged in for me. Have you explicitely tested this? Maybe I have to retest with some newer code from the alsa tree?
