Runnnig 3.11-rc6 and seeing the same problem (on Ubuntu). Seems that after a suspend&resume cycle the headphones also cease to work.
With 3.11 sound (via the headphones) keeps on working even after the resumes.

I'm experiencing the same issue. also, jack sensing does not work. Apple did a full HW refresh for the 2013 MacBook Air, so some devices are not recognised - including the Cirrus audio system. kernel bug https://bugzilla.kernel.org/show_bug.cgi?id=60811 has a patch for Alsa that fixes the issue.
still happening with Fedora 20.
I've just put Fedora 19 on a MacBookAir6,2, and I can confirm this issue is happening for me too.
Fedora 20 kernel-3.12.5-301.fc20.x86_64 Lenovo Y470p 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) There is no sound via speakers after boot. But after plugging/unplugging the headphones (via 3,5 mm jack) the sound (via speakers) comes back. BTW, the headphones work fine.

it seems 3.12.8-300 already fixed the issue for me: I get jack sensing, and the speaker works. I guess this bug can be closed.
Thanks.
