I had similar problems on an MSI based laptop. Since the recent updates to 2.6.31-15 the external microphone now works as microphone 1 and the internal one as microphone 2. Before the above update, I couldn't connect the external Mic port at all.
Tried the "backports" solution with no success and I had boot problems here as well. -- External microphone jack not working on Dell Studio 1735 notebook. https://bugs.launchpad.net/bugs/479410 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
