Bug#701591: pulseaudio: Fails to play sound after a while (random event)

[Thomas Barandon]

Package: pulseaudio
Version: 3.0-1
Severity: important

Dear Maintainer,

Since the update to version 3.0-1 a problem appeared, pulseaudio no longer play
sound after a while.
This problem seems to be also related to vlc, no problem appeared for several
hours when vlc was not open or playing something.

VLC provide me this error when i try to play something:
[0x7f048400bc38] pulse audio output error: overflow, flushing

All application using pulseaudio stop playing sound.

After that error it's necessary to do a pulseaudio -k and restart all
application using pulseaudio.
I edited the daemon.conf to change the default sample rate to 48000 and this
seems to fix the problem (just a workaround).

How can i provide more detailed logs ?

Thank you,
Thomas
