I'm not 100% sure that I'm following you, but let me tell you what I've done, according to what I've read in the bug report you've linked.
I've run a series of commands which yield the indicated output (see the attachment). In addition I've later edited the file: /etc/modprobe.d/alsa-base.conf adding the following line at the end: options snd_hda_intel index=0 model=mbp81 and reloaded alsa by running: sudo alsa reolad Nothing of this has resulted in the micro working at all. ** Attachment added: "Some commands and their output." https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1566596/+attachment/4628276/+files/someoutput -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1566596 Title: MBP 8,2 internal microphone stopped working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1566596/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
