Public bug reported: After installing Raring on my 2013 MacBook Air 6,2, I get no sound in the speakers, nor the headphones.
After checking alsamixer and seeing that it had the wrong card by default (it also has an HDMI card), I added "index=1" to the snd-hda- intel options, which turned up the correct card in alsamixer, but still no sound. Everything looks correct in the Sound settings as well as in alsamixer. I noted that snd-hda-codec-cirrus isn't loaded -- manually loading it has no effect. I have also tried passing "model=auto" and "model=mbp55" as module options, to no avail.
