Comment 27 for bug 1227093

Ok, so the mic patch was just merged with cc to 3.11 stable, so it's likely to be fixed in an SRU or two (should show up by a robot comment in this bug when it happens). Until then, you can use https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS (starting tomorrow probably, as it needs to go through a few systems first).

As for the headset mic, I have no further ideas at the moment. If someone has a CTIA headset nearby, it would be worth testing that.
