*push* this happens on the MacBook 6,1 (late 2009) as well. It has the same Cirrus CS4206.
I just tested the most recent alsa-daily which builds for wily/amd64 without effect. Internal Speakers, Internal Mic, Headphones all work - TRRS mic doesn't work (Mac OS X supports exactly this Headset device out of the box). I'm using 15.10 GNOME Ubuntu. In sound settings I can only activate the internal mic and don't even see any external (as with output where the label of the output device automatically changes if the headset is connected). uname -r Linux macbook 4.2.0-23-generic #28-Ubuntu SMP Sun Dec 27 17:47:31 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux running alsa-info.sh (with headset connected) => Your ALSA information is located at http://www.alsa-project.org/db/?f=7556cfd21195211e5d8bd44184d481b0bd26d892 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1329191 Title: [MacBookAir5,1, Cirrus Logic CS4206, Blue Line In, Rear] Line In using TRRS plug does not work correctly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1329191/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
