For what it is worth, the exact same problem also surfaces on the Macbook Air 1,1. Everything seems to be working fine; sound card is recognised and alsamixer shows the various channels as active and unmuted. But no sound comes out of the speakers.
The problem for the Macbook Air 1,1 is reported on various sites, among here: http://ubuntuforums.org/showthread.php?t=2141179 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1181828 Title: macbook air 2,1 no sound Status in “alsa-driver” package in Ubuntu: Confirmed Bug description: Hello, I installed Ubuntu raring 13.04 on a Macbook Air 2,1 and I have no sound.
