Maybe. From the bug, it's hard to tell. But here's what I think. I think that the kernel made changes recently that changed how sound relates to the kernel, and tied pulseaudio closer to the kernel (hence those error messages I got under 2.6.28-11, which kernel was acknowledged to be buggy the day it came out). Some of the bugs they either backed out or corrected with 2.6.28-12. It would be interesting to see if they can get steam running with that kernel. If you are working with the steam-bug people ask them to add the below kernel, purge pulseaudio, and test with alsa only. http://kernel.ubuntu.com/~dtchen/test-kernels/ Of course, they need headers, image & restricted modules.
