Comment 0 for bug 688423

I installed linux-backports-modules-alsa-2.6.35-23-generic, following a recommendation in a forum, but this did not solve my problem.
In Lucid, after instaling the linuxant driver, capture in alsamixer showed me an option to select a mic, and selecting mic F made everything work). Now alsamixer doesn't show anything to select a microphone.
