PulseAudio ALSA-plugin streams "hang" on suspend/resume

[clconway]

I've had this problem particularly with the Flash plugin to Firefox, but also with Totem and Amarok. This happens any time I suspend the computer while there is an active "ALSA plugin [firefox]" stream in pavucontrol. On resume, the pulseaudio daemon logs the following messages:

D: module-hal-detect.c: dbus: interface=org.freedesktop.Hal.Device, path=/org/freedesktop/Hal/devices/computer_logicaldev_input_4, member=Condition
W: module-alsa-sink.c: Got POLLERR from ALSA
D: module-hal-detect.c: dbus: interface=org.freedesktop.Hal.Device, path=/org/freedesktop/Hal/devices/computer_power_supply_battery_BAT0, member=PropertyModified

After resume, no applications can play sound and videos freeze up. There is still an "ALSA plug-in [firefox]" stream in pavucontrol. Terminating the stream allows other (non-Firefox) applications to play sound. Restarting Firefox re-enables sound in Flash videos.

I have previously reported this bug to Ubuntu Launchpad and ALSA Mantis with no resolution. Additional information, including system logs, is available in Launchpad.

This problem disappeared after I wiped my disk and did a fresh OS install (for unrelated reasons). Obviously, it had something to do with bad configuration files. I still have backups of my old configuration files, and would be glad to provide any requested information if it would help solve this problem for others.

I am pretty sure we handle suspend/resume properly these days in PA. Remaining issues usually point to driver problems. Since the problem is gone anyway for the reporter and 0.9.10 is pretty old I am closing this now.
