Definitely a displaylink bug. Runtime power management should suspend things when they aren't in use, which includes the entire tree of USB devices, so the kernel is working exactly as intended. The way the displaylink part uses a userspace driver works is a bit odd and issues like this are more likely to occur. Forcing the audio driver to never suspend is just a workaround (and a waste of power).
