Comment (by tidux):

 Still present in Beta 1.  It looks like the channels are being mapped as
 inputs when they're outputs or vice versa.  Looking at the Linux kernel
 code for the HDA driver and eyeballing the comparison it looks like
 there's a lot more work going into device initialization on the Linux
 side... and this laptop's sound works on Linux.  Might be a place to look.
