im using Ubuntu Jaunty and have problems with sound in PD 0.41.4-extended
when using simultaneously Firefox and/or Audacious.

If i start PD sooner then firefox and audacious, they dont make any sounds
but sound in pd works ok. If i start PD later, firefox and audacious work
fine, but sound in PD gets stuck with:
snd_pcm_open (output): Device or resource busy (in the shell)
audio I/O stuck... closing audio (in pd console)

Both FF and Audacious are using the pulseaudio server. I tried to create a
/etc/asound.conf, to create a new device:

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

and use it with pd -alsa -alsaadd pulse, but the audio output in pd still
doesnt work when running some other sound applications. When running pd
alone like this, the sound is severely garbled and after a while it hangs
the same...

Is there some normal way how to handle this ? I mean it should not be a
problem using several application at once but apparently pd has some
problems with it..

Thanks for any advices..
