#923: client app: playback on first buffer, then underrun and no audio
------------------------+---------------------------------------------------
 Reporter:  kirkawolff  |       Owner:  lennart 
     Type:  defect      |      Status:  new     
Milestone:              |   Component:  libpulse
 Keywords:              |

 Sound works fine on a ubuntu maverick system.  The following error log is
 on a debian system, in a virtualbox machine, that didn't have pulseaudio
 installed.  It was installed with a simple 'apt-get install pulseaudio
 libpulse-mainloop-glib0' where other dependencies are installed along with
 it.  On the debian system (derkins) log shown below, pulseaudio appears to
 work with media programs such as VLC.

 I've written a simple asynchronous tone-generating program which
 interactively plays morse-code.
 The log below is generated by the source code at:

 http://morse-coach.svn.sourceforge.net/viewvc/morse-coach/trunk/morse-
 coach/src/morse_sound.c?view=markup

 The first buffer of sound is played (about 2 seconds), but after the first
 buffer runs-out the write_cb never gets called asynchronously but the
 _underrun_cb does.  Could this have to do with a problem with the default
 prebuffer settings on this system?  I'm not setting prebuffer in my
 source.

 You will notice (at the end of Mar 20 22:19:26) the stream gives a 'died'
 message before its even reached the connected state.
