OK, I was able to successfully apply the patch and build the kernel. I
tested it using:
$ pasuspender bash
$ speaker-test -Dplug:surround51 -c6
Once I set sound to 6-channel using alsamixer -c0, I was able to hear
the sound for all 6 channels. Setting it to 4 channels took away LFE and
center. Pulseaudio outputs are still a little messy, but this is out of
ALSA scope, I think.
