I can confirm that the internal microphone doesn't work. I have Acer Aspire 8943G as well.
I have also tried the package linux-alsa-driver-modules-2.6.38-8-generic version 2.6.38-8.201105230750 from Ubuntu Audio Dev PPA and a bunch of "model" options for snd-hda-intel in /etc/modprobe.d/alsa-base.conf (among others to get the 5.1 surround built-in speakers to work - Ubuntu only recognizes them as 4.0 and the center speaker and subwoofer are not functional at all then) but with absolutely no result. As dreKion wrote, the chip is ALC670. I am using Ubuntu natty. If you need any additional info, please let me know.
