I have an EMU Tracker Pre USB audio interface and was experiencing the muted audio after suspend in Ubuntu 12.04, and after removing /usr/lib/pm-utils/sleep.d/01PulseAudio the interface would crash (all lights on) and the computer would hang coming out of suspend until the interface was disconnected from USB.
