Description:

On each boot I get the following message.

Dec 03 07:22:38 thinkpad rtkit-daemon[1450]: Successfully made thread 1449 of process 1449 (/usr/bin/pulseaudio) owned by '1000' high priority at nice level -11.
Dec 03 07:22:38 thinkpad rtkit-daemon[1450]: Supervising 1 threads of 1 processes of 1 users.
Dec 03 07:22:50 thinkpad rtkit-daemon[1450]: Successfully made thread 1599 of process 1599 (/usr/bin/pulseaudio) owned by '1000' high priority at nice level -11.
Dec 03 07:22:50 thinkpad rtkit-daemon[1450]: Supervising 2 threads of 2 processes of 1 users.

Dec 03 07:22:50 thinkpad pulseaudio[1599]: [pulseaudio] pid.c: Daemon already running.

Additional info:

I don't use any DE but Openbox only which I run from .xinitrc.

I left pulseaudio completely unmodified and do not start it explicitly, at least not that I am aware of.

To me it seems that something is starting the daemon multiple times.

Steps to reproduce:

Install lib32-libcanberra-pulse 0.30-4, lib32-libpulse 4.0-6, libpulse 4.0-6, pulseaudio 4.0-6, pulseaudio-alsa 2-2

Leave all default and start your system.

This is when I get this message.
This task depends upon

Attach your .xinitrc maybe you start it there, or in your openbox config

Not that I am aware of.
   .xinitrc (1.4 KiB)
   autostart (0.6 KiB)

Could it be caused by having the following two files in /etc/xdg/autostart?

pulseaudio-kde.desktop
pulseaudio.desktop
Comment by Robert Orzanna (orschiro) - Sunday, 08 December 2013, 10:28 GMT
I moved both files to {.bak} to test whether pulseaudio will still successfully start and indeed it does. However, I have no idea what is starting up pulseaudio then. Any idea what is starting pulse?

~ $ ps aux | grep pulse
orschiro 1134 2.6 0.1 353932 12252 ? S<l 10:05 2:07 /usr/bin/pulseaudio --start
orschiro 1304 0.0 0.0 69216 2380 ? S 10:05 0:00 /usr/lib/pulse/gconf-helper
orschiro 31666 0.0 0.0 12620 1068 pts/2 S+ 11:27 0:00 grep pulse

Are the .desktop entries in /etc/xdg/autostart really necessary?

I can confirm this happens to me in Xfce as well. It is clearly a widespread bug, but nearly nobody notices it. The point is, there does not seem to be any need to have .desktop files in the xdg folder relating to pulseaudio. Even the script in X11/xinit isn't needed. As long as pulseaudio is installed, it seems to start at boot even though nobody seems to be able to explain what is starting it. Please also see my discussion of this: https://bbs.archlinux.org/viewtopic.php?id=175241

I've discovered why pulseaudio is starting even without any pulseaudio files in /etc/xdg or in /etc/X11/xinit/xinitrc.d/. The Display Manager is starting it If you disable the Display manager (and also remove all the pulseaudio files from /etc/xdg and /etc/X11/xinit/xinitrc.d) then pulseaudio won't run at all. If you leave all the pulseaudio files alone, but just disable the DM, then pulseaudio will run and you won't get any errors about it trying to run twice. I want the DM though, so for now, my solution is to delete all those pulseaudio files from the xdg and X11 directories. Really, those files need to be modified to account for the possibility that the DM already started pulseaudio.

Please see  FS#38412  - [pulseaudio] pid.c: Daemon already running, Prevent by modifying ...xinitrc.d/pulseadio & PKGBUILD (https://bugs.archlinux.org/task/38412) that I have reported.

Fixing this properly would require revamping PulseAudio's lifecycle management to use, e.g., the systemd user manager in order to be launched reliably and early enough. Ideally using socket activation.

Right now it's a mess of libpulse's own autospawn and various startup methods (XDG, xinit.rc), potentially racing with each other and then aborting with "daemon already running."

I'm not going to invest loads of time fixing this downstream just to avoid a warning.

I forgot the xinit stuff was our downstream patch.

In the interest of keeping the package vanilla, would removing the xinit script and reactivating autospawn be a solution?
