Comment 3 for bug 33719

Yes, you'll need current cvs snapshots (1.0.11rc3 is insufficient, as work was merged post-1.0.11rc3) of the alsa-driver and alsa-kernel modules. You'll need the build-essential, automake1.9, autoconf, and cvs packages installed. Instructions for generating the hda-intel driver from cvs are found in the INSTALL file (scroll halfway through the file and follow the cvs instructions section) of alsa-driver, which you'll checkout.

I am currently working to push the necessary changes into a git branch so they can be considered by the kernel team lead.
