Having seen this bug I thought I would do some testing since I was still on the 2.6.31-4 kernel and running pulseaudio 1:0.9.15-4ubuntu2 and sound was working fine. First, I specifically updated just the kernel to 2.6.31-5 and sound still worked fine. I then updated pulseaudio to 1:0.9.16~test4-0ubuntu4 and now I no longer have sound. I tried doing "pasuspender -- rhythmbox" but still have no sound.
I notice Jamie is seeing a similar issue in bug 400682 but I don't think these are duplicates since he experienced his loss of sound upgrading to an earlier Karmic release whereas we just recently lost sound.
