I have two Thinkpad Edge 13 notebooks in the family and neither of them have working microphones, even with kernel 2.6.38-8 in Natty.

I tried setting the "model" parameter in snd-hda-intel to all the alternatives that are available and still no luck. When I ran "alsa-info.sh" it indicated that these machines use the Conexant 5066 chip with vendor ID: 17aa:21b3.

I had a look in the kernel source and found a file "sound/pci/hda/patch_conexant.c". This lists the machines that use the 5066 chip, but the only vendor IDs listed for the Edge 13 are 17aa:21c5 and 17aa:21c6. This suggests to me that Lenovo have produced another variant of the Edge 13 that does not work with the fix discussed above.

Maybe this bug should be reopened?

Mal, you're probably having different hardware than the Edge 13 that we certify. Could you please file a separate bug using "ubuntu-bug audio"? Thanks!
