pulseaudio fills logs with "Root privileges required" messages

[bogdanb]

The problem is described in more detail on the Ubuntu tracker: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/95513

In short, I get the logs filled with messages like:

Jun 17 15:36:27 cimer pulseaudio[12365]: main.c: Root priviliges required.

one or two of which are displayed each time I start an application that can use sound. (This includes gedit, but not vi, for instance.) The sound works correctly as far as I can tell, but the logs are spammed with so many messages it becomes hard to notice other errors.

I'm using pulseaudio version 0.9.6 with Ubuntu Gutsy Gibbon, from the standard Ubuntu repositories.

This message is printed on every startup, when started as normal user (who is not part of the "rt-pulse" group) but configured for realtime scheduling. The syslog dumps shown in the LP bug report clearly show that the PID changes every line, i.e. you are probably running PA on-demand, and not (as the reporter suggests) as a single system-wide instance.

To fix this either properly configure your PA clients to use the system-wide daemon. Or add the specific user to the "pulse-rt" group. (which however, has some security implications, YMMV) Or disable rt scheduling for your user.
