Same happens to me. After resuming, I can get sound working with killall pulseaudio. However, when I do, gnome-power-manager starts using large amounts of cpu and memory. After killing pulseaudio, I watched the Memory column in gnome-system-monitor climb quite rapidly. It reached 1.3 GB while I was watching before I killed gnome-power-manager. I'm using Ubuntu amd64 Beta with all updates applied.
