A git branch? Where can I get it? The sound tree is at: https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/ You can use the master branch now, it has been merged there. > How independant is the sound subsystem from the rest of the kernel?

Will upgrade to 3.12 in a couple of day.... Often you can just copy the sound/pci/hda directory from a newer kernel and then build the modules for the current kernel ("make -C/lib/modules/$(uname -r)/build M=$PWD") with only minimal changes and possibly disabling unused modules in Makefile. -- Anssi Hannula
