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
[https://bugs.launchpad.net/bugs/302276 Ubuntu Launchpad] and
[https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4320 ALSA Mantis]
with no resolution. Additional information, including system logs, is
available in [https://bugs.launchpad.net/bugs/302276 Launchpad].
