taking a look at a diff with the older version of alsa, you can see the AC_VERB_SET_CONNECT_SEL changed from 1 to 2:
2822c2944
< {0x14, AC_VERB_SET_CONNECT_SEL, 1}, /* default to internal mic */
---
> {0x14, AC_VERB_SET_CONNECT_SEL, 2}, /* default to internal mic */
if you dont want to go down that path, consider installing snd-hda-tools (add repos "deb http://ppa.launchpad.net/diwic/ppa/ubuntu lucid main" and "deb-src http://ppa.launchpad.net/diwic/ppa/ubuntu lucid main") and then use hda-verb to change the settings previously changed using hda-analyzer. you will need to figure out the options for hda-verb, i worked out how to change the audio selector:
looks like this has been fixed in newer versions of alsa - i downloaded this version: http:// ftp.kernel. org/pub/ linux/kernel/ people/ tiwai/alsa/ alsa-driver/ alsa-driver- 20101221. tar.gz and compiled and installed (./configure; make; make install) and now my mic works all the time, even after a reboot. i think the relevant fix is in the file alsa-driver/ sound/pci/ hda/patch_ conexant. c:

see the following ubuntu post for ideas on setting up a script to automate hda-verb: http:// ubuntuforums. org/showpost. php?p=9826074& postcount= 121
id go with installing the newer version of alsa though...
