External microphone support on LG S1 laptop

Fixed in upstream 1.0.14rc1.

The situation is the same with Feisty. No microphone unless you unplug, deselect, plug and select it.
Was the upstream fix committed to Feisty?

Not fixed in upstream alsa-driver, -lib and -utils versions 1.0.14rc4. So, this bug should be re-opened.

Use current hg.

What is hg? I don't understand.
I used the Feisty version (1.13) for several months, and the problem was there. I tried to install the upstream version because it was supposedly fixed there, but apparently it wasn't.
I reported the problem in ALSA bugtracking system as well: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3125
