PulseAudio fails to launch in system mode in CentOS 7
Long story short, I'm trying to setup PulseAudio to act as a loopback interface for a local music stream. However, I'm hitting a breaking point in getting it setup.
As I understand it, you cannot start pulseaudio in "non-system mode" without having an X server running, but seeing as the server is is headless this is not an option. So I began writing a cobbled together systemd script to start the daemon as a system-wide instance. This however fails for some inexplicable reason.
If I run the command that in in the systemd script, the system-wide pulse starts up just fine! However, if I run it from within the start script (eg. with systemctl start pulseaudio), it fails with Failed to create '/var/run/pulse': Permission denied
. I can't for the life of me figure out how it would work for the same user in to different ways. I also tried replacing the start script with a ls /var/run/pulse
. When the script is setup to run as "pulse", it prints nothing in the journal. However, if I wrap the whole call in a sudo -u pulse
, it prints the contents of /var/run/pulse
. When I wrap the pulse startup command in a sudo -u root
, it just crashes with the same error.

This doesn't really explain the Failed to create '/var/run/pulse': Permission denied
message, but there's one apparent issue in your configuration, which is that you're running PulseAudio with --daemonize
from the systemd service unit, while systemd actually expects it to run in foreground. You should change that to --daemonize=no
.
You might also want to explicitly list --disallow-exit
and --disallow-module-loading
as suggested from the log messages.
PulseAudio is also complaining that user pulse
's home directory is not /var/run/pulse
, as it seems to expect that, you might want to update the system account to reflect that.
For further research, you might want to look at this article for more details and instructions on running a system-wide instance of PulseAudio, and also this page from the PulseAudio wiki (including some references on why you would not want to run PulseAudio as a system-wide service.)
My working theory at the time was that pulse wasn't understanding the symlink from/var/run
to/run
so I had adjusted the home directory of the pulse user to/run
. This however did not resolve the issue. I also tried with those options in there, and it didn't seem to do anything.

The symlink is there so applications using the/var/run
paths can run unmodified. I suggest you just use/var/run
paths everywhere. (Right now you have a mix of both!)

Nov 7 '18 at 1:08
The fact is it tries to make/var/run/pulse
even though it exists and by all rights should be able to see that it does./var/run/pulse

Nov 7 '18 at 1:23
Is it possible this is SELinux related? Do you have it enabled? Do you have messages about AVC in your logs?
– filbranden
Nov 7 '18 at 2:52
In any case, the other problems mentioned are issues you'll have to address, so I suggest you start with those, see if it's still not working and then we can look at what's next...

You can try putting pulseaudio.service with --user in a shell script to start it. Now run the start script inside screen as a normal user. Then detach the screen and logout. The pulseaudio server continues as if it were headless.

so I had adjusted the home directory of the pulse user to/run
. This however did not resolve the issue. I also tried with those options in there, and it didn't seem to do anything.

The symlink is there so applications using the/var/run
paths can run unmodified. I suggest you just use/var/run
paths everywhere. (Right now you have a mix of both!)

The fact is it tries to make/var/run/pulse
even though it exists and by all rights should be able to see that it does./var/run/pulse
->/run/pulse

Is it possible this is SELinux related? Do you have it enabled? Do you have messages about AVC in your logs?

In any case, the other problems mentioned are issues you'll have to address, so I suggest you start with those, see if it's still not working and then we can look at what's next...

This doesn't really explain the Failed to create '/var/run/pulse': Permission denied
message, but there's one apparent issue in your configuration, which is that you're running PulseAudio with --daemonize
from the systemd service unit, while systemd actually expects it to run in foreground. You should change that to --daemonize=no
.
You might also want to explicitly list --disallow-exit
and --disallow-module-loading
as suggested from the log messages.
PulseAudio is also complaining that user pulse
's home directory is not /var/run/pulse
, as it seems to expect that, you might want to update the system account to reflect that.
For further research, you might want to look at this article for more details and instructions on running a system-wide instance of PulseAudio, and also this page from the PulseAudio wiki (including some references on why you would not want to run PulseAudio as a system-wide service.)

My working theory at the time was that pulse wasn't understanding the symlink from/var/run
to/run
so I had adjusted the home directory of the pulse user to/run
. This however did not resolve the issue. I also tried with those options in there, and it didn't seem to do anything.

You can try putting pulseaudio.service with --user in a shell script to start it. Now run the start script inside screen as a normal user. Then detach the screen and logout. The pulseaudio server continues as if it were headless.
