I got an Acer Aspire 4551-2728 earlier this year, and now I have some |
| 2 |
spare time on my hands, and I've got it almost 100% functional under 64 |
| 3 |
bit Gentoo linux. The networking was dead easy, as was the video (once |
| 4 |
I was pointed to the instructions). The webcam took some digging, but |
| 5 |
I figured it out, with "Mr. Google's" help. The last item that doesn't |
| 6 |
work yet is the internal microphone. |

Has anybody gotten an internal microphone on any Acer laptop working? |
| 9 |
My Google searches have found a couple of references to "it works out of |
| 10 |
the box" under some versions of Ubuntu, but no technical details, which |
| 11 |
doesn't really help. Here are a few snippets from alsa-info... |
