"For now i can work around this by disabling suspend-on-idle in /etc/pulse/default.pa:
### Automatically suspend sinks/sources that become idle for too long
#load-module module-suspend-on-idle
I regard this as what it is: just a workaround."
I confirm that this workaround works for me ( x-station usb 1.1/ snd-usb-audio ). Sound output is stable now. I bet the bug is in pulseaudio's suspend - resume code, but it happens with usb-audio devices. My onbord mobo ac97 doesn't have this problem.
I still see the underrun messages in verbose mode (txt included). There appears cracks in the sound output time to time. Seems like a buffer under/overrun issue to me as stated in the verbose messages. But I think this has nothing to do with our original problem. May be a bug in the alsa's usb driver or a bug in pulseaudio again. I didn't have these cracks back in ubuntu 8.04.
