This problem also effects my system. Internal speakers refuse to work. Microphone doesn't show any input, although it was working when I installed Natty (indicating that it was an update that caused this error).
I'm going to go ahead and confirm this, because I know something is wrong with this, and I'm not seeing any duplicates that match this. However, someone may find a bug that better fits as a duplicate to move this to. Until then, to be on the safe side, run "apport-collect 772276" in a terminal to collect debugging information for the developers to diagnose any problems related to this bug report. ** Changed in: pulseaudio (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/772276 Title: Cannot use Web Cam Microphone -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
