Hi, I can also confirm similar bug with Macbook Pro 13 inch (8.1 rev I think). I have a iphone headset, which works fine for both headphone and mic in Mac OS, but the mic doesn't even get detected in ubuntu precise. In gnome sound settings, there is only option for internal mic.
Here is output of "hda-jack-sense-test -a" $ sudo hda-jack-sense-test -a Pin 0x09 (Green HP Out): present = Yes Pin 0x0a (Internal Speaker): present = No Pin 0x0b (Internal Speaker): present = No Pin 0x0c (Not connected): present = No Pin 0x0d (Internal Mic): present = No Pin 0x0e (Not connected): present = No Pin 0x0f (Not connected): present = No Pin 0x10 (White SPDIF Out): present = No Pin 0x12 (Not connected): present = No Pin 0x15 (Not connected): present = No My alsa-info.sh output http://www.alsa-project.org/db/?f=c9ae2b59e879dac322f33a0236d59014d30366d4 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/950494 Title: [Macbook Air 3,2] headset mic not recognized To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/950494/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
