I see a flood of PA error messages in syslog recently: Sep 27 18:48:16 planemask pulseaudio[1626]: reserve-wrap.c: Failed to acquire reservation lock on device 'Audio0': Input/output error Sep 27 18:48:38 planemask pulseaudio[1626]: reserve-wrap.c: Failed to acquire reservation lock on device 'Audio0': Input/output error Sep 27 18:48:57 planemask pulseaudio[1626]: reserve-wrap.c: Failed to acquire reservation lock on device 'Audio0': Input/output error Sep 27 18:49:18 planemask pulseaudio[1626]: reserve-wrap.c: Failed to acquire reservation lock on device 'Audio0': Input/output error Sep 27 18:49:39 planemask pulseaudio[1626]: reserve-wrap.c: Failed to acquire reservation lock on device 'Audio0': Input/output error Sep 27 18:49:50 planemask pulseaudio[1626]: reserve-wrap.c: Failed to acquire reservation lock on device 'Audio0': Input/output error Sep 27 18:50:00 planemask pulseaudio[1626]: reserve-wrap.c: Failed to acquire reservation lock on device 'Audio0': Input/output error Sep 27 18:50:20 planemask pulseaudio[1626]: reserve-wrap.c: Failed to acquire reservation lock on device 'Audio0': Input/output error Sep 27 18:50:29 planemask pulseaudio[1626]: reserve-wrap.c: Failed to acquire reservation lock on device 'Audio0': Input/output error Its neverending. Can we stop that ?
I'll lower the log level. That way it will be shown only in debug mode. This happens when you quickly log out and back in so that your PA instance is reused, but its session bus is not existant anymore.
Fixed upstream now. Will prep new upload soon.
