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
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),
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?
