After suspend/resume, audio does not start playing on main speakers but on other devices, need to restart pulseaudio

[Nikolaus Waxweiler]

I have 2 audio systems hooked up via USB: the headphone amplifier with a DAC and my active speakers. Since 12.10 (didn't happen on 12.04), when I resume from a suspend and want to play some audio file with the system that was active before suspend, audio **sometimes** hangs, meaning the track cursor stays at the start and nothing happens. When I switch to my other system, e.g. headphones, everything works alright. When I switch back to the system before that, audio stops playing again. It's like the sink that was active before suspend never gets resumed. Killing pulseaudio and opening the sound menu to start it again solves the problem and everything is back to normal.

PS: I filed this report after restarting PA, so PulseList.txt probably contains normal data... will try to attach more logs when it happens again (audio doesn't always hang after resume, forgot to clarify).

Alright, I currently have the Spotify web player (uses Flash) open in Firefox. I listened to some music, pressed pause and suspended. After resuming and clicking play, nothing happens, progess bar doesn't move, no sound. When I switch to my other sound system, everything works as expected. Switching back results in the player stopping in its tracks, progress bar doesn't move, no sound.

I found that there are multiple entries for my one system, with and without (what I want) bass boost und SPDIF output. When playback doesn't work, I click on the other entries for that system and then to the one that hung, then it works without restarting. Like something gets flushed.
