guys there's a fix. i have a 2013 mba. the problem is in applehda. you can look at the hpet shoot up after sleep using `powermetrics`

here's a video to reproduce the issue

and here's a dmg that has the fix. basically it replaces applehda with the one from 10.8.5

i've been using it happily for ten days. some people claimed it wouldn't work with haswell, but it does for me. YMMV though

it doesn't work for rmbp 2013 late.

i think the latest mbp's might have a different product id on the intel hda. does your sound disappear with the old driver?

yep. but it solved the kernel 100% problem.
