If I understand correctly, the chips use same subsystem ids, so the patch does not automatically detect the correct chipset. Maybe someone more knowledgeable can help with this? The patch names the internal mic as Int Mic and external mic that can be plugged in as Ext Mic.

Thanks for looking at this. I tested this against kernel 2.6.22.9 from
kernel.org and the patch seems to do the trick. Without
alc262_EAPD_verbs sound does not work and the mic settings need to be
added to get the mic working.

I do not have any other laptops using the same chip available for
testing, so I cannot say whether this affects other models using the
same chip.

Below is the diff from the actual sources that I used to test this:
