Upon the install of 8.04 LTS, my sound will only play from one source, and even if I close that source, I have to restart the other program that I am trying to use first. I have seen this bug/problem reported before, but saw something that looks interesting in the verbose report from pulseaudio. Take a look at the red section and tell me what you think. I have no idea whether it's significant.
