Here's what seemed to have worked for me. I downloaded Pulse Audio Volume Control (sudo apt-get install pavucontrol), and fiddled with the controls in it.

Nevertheless, the mic works in google chat and skype. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/990211 Title: [Dell XPS 14] Mic not working in Ubuntu 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/990211/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
