Can't record sound with built in mic

[Brandon M]

I can play back sound easily on this laptop, but recording doesn't work.. The sound preferences doesn't show any audio levels, even if i select mic or line in.. I didn't test line in to see if that input works. Audacity doesn't pick up sound either.

Plesae try updating yoru ALSA drivers, as outline here: https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules. Once you have done this, please report back as to whether you can record sound.

Thanks for the suggestion Luke, that worked, microphone input is now working great!
