Bug ID: 106540
Summary: SIGPIPE on pa_write
Product: PulseAudio
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: core
Assignee: pulseaudio-bugs@lists.freedesktop.org
Reporter: aa...@kde.org
QA Contact: pulseaudio-bugs@lists.freedesktop.org
CC: lenn...@poettering.net
I can reproduce this 100% by making Okular produce two sound notifications (not
very quickly one after the other)
I'll be reporting this to gstreamer too
Thread 21 "queue0:src" received signal SIGPIPE, Broken pipe.
