Binary package hint: pulseaudio

For some strange reason, I don't know why PulseAudio crashed when I open
up ZynAddSubFX, but when I close it, start PulseAudio, and open
ZynAddSubFX, it seems PulseAudio does not crash.

This is what I have for PulseAudio/JACK in /etc/pulse/jack.pa:

#!/usr/bin/pulseaudio -nF
#
load-module module-jack-sink
load-module module-jack-source

load-module module-native-protocol-unix
load-module module-volume-restore
load-module module-default-device-restore
load-module module-rescue-streams
load-module module-suspend-on-idle
.ifexists module-gconf.so
.nofail
load-module module-gconf
.fail
.endif
.ifexists module-x11-publish.so
.nofail
load-module module-x11-publish
.fail
.endif

This is how I setup my ALSA-PulseAudio bridge:

pcm.pulse
{
    type pulse
}
ctl.pulse
{
    type pulse
}
pcm.!default
{
    type pulse
}
ctl.!default
{
    type pulse
}

I will have to restart my netbook to see if the crash occurs again.
