I bought a Inspirion 3520 for XMS, and I installed on it a Ubuntu 12.04 LTS partition. Almost everything work on it, except my microphone. I can't use it. This is a big issue for me because I need to use Sky and Google hang out regulary!
I probe a lot of things, even I installed the ubuntu audio dev repository->(https://launchpad.net/~ubuntu-audio-dev/+archive/ppa)
But nothing seems to work.
If someone could help me I will be really glad!
