This issue is a little similar to bug 67998. I solved another problem (see my message on that bug report) by issuing (essentially) the same commands as you did, ^rooker.
These are not the same bug, though, as this report refers to the lousy error message given by gnome-sound-recorder. -- "Your audio capture settings are invalid. Please correct them in the Multimedia settings." is a really unhelpful error message https://launchpad.net/bugs/61211 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
