I got an Acer Aspire 4551-2728 earlier this year, and now I have some spare time on my hands, and I've got it almost 100% functional under 64 bit Gentoo linux. The networking was dead easy, as was the video (once I was pointed to the instructions). The webcam took some digging, but I figured it out, with "Mr. Google's" help. The last item that doesn't work yet is the internal microphone.
Has anybody gotten an internal microphone on any Acer laptop working? My Google searches have found a couple of references to "it works out of the box" under some versions of Ubuntu, but no technical details, which doesn't really help.
