Not really my area of specialty, but there is a lot of traffic on the
ALSA-devel list relating to laptop specific configuration of mic or
headphone etc.  Various quirks get added as they are discovered.

http://search.gmane.org/?query=acer++mic+realtek&author=&group=gmane.linux.alsa.devel&sort=relevance&DEFAULTOP=and&xP=Zacer%09Zmic&xFILTERS=Glinux.alsa.devel---A

I.e. search http://search.gmane.org/ group gmane.linux.alsa.devel for
"acer, mic, realtek"

I don't have time to wade through all that, but you may discover that
the latest ALSA version contains a fix, or help in getting such a fix made.
