Hello,
PulseAudio daemon crashes after starting the second stream.
The first stream is playing with some audio glitches and then I start the
second stream and it causes the server shutdown. I do not hear any audio
afterwards.
pulseaudio --system
gst-launch filesrc location=some_mp3.mp3 ! mad ! audioconvert ! pulsesink
latency-time=25000 buffer-time=2000000 &
after few seconds and i launch another media playback
gst-launch filesrc location=some_another_mp3.mp3 ! mad ! audioconvert !
pulsesink latency-time=25000 buffer-time=2000000 &
And this causes PA shutdown.
In ps I see that both the gst-launches are active and I do not hear any
audio untill the PA is re-launched.
See the attachemnt for PA traces.
-Rgds
Vallabha
