Intermittent problems (Unable to connect)

[hugobo]

When I play the exact same audio or video file in audacious, xine or mplayer, I sometimes have this error message (audacious example):

*** PULSEAUDIO: Unable to connect: Invalid argument
ERROR: libflacng.so: plugin.c:366 (flac_play_loop): Could not open output plugin!

I'm using pulseaudio-0.9.7

Here is the log output from pulseaudio:

What can be the problem?
