Bug#731300: E: [autospawn] core-util.c: Failed to create secure directory (/run/user/0/pulse: Permission denied

[Trey Blancher]

Package: pulseaudio
Version: 4.0-6+b1
Severity: important

Dear Maintainer,

I reinstalled my Debian sid system after a hard drive failure, and noticed that
pulseaudio wasn't working:  I had no sound, and pavucontrol fails to connect to
the daemon.  I ran pulseaudio from a zsh console, and I got this result:

pulseaudio --daemonize --start
E: [autospawn] core-util.c: Failed to create secure directory
(/run/user/0/pulse): Permission denied
W: [autospawn] lock-autospawn.c: Cannot access autospawn lock.
E: [pulseaudio] main.c: Failed to acquire autospawn lock

It appears that pulseaudio is trying to open the lock in root's (UID 0's)
/run/user/ directory, not my user (UID 1000).  It does not appear that
pulseaudio is setuid root, as the following shows:

ls -l $(which pulseaudio)
-rwxr-xr-x 1 root root 83K Sep 12 05:12 /usr/bin/pulseaudio*

Nothing I've tried has worked.  I have ensured my user is part of the audio,
pulse, and pulse-access groups.  I see bug #576769 which seems to report the
same issue, but doesn't report the actual name of the secure directory attempted.
My attempt to build from source (as suggested by #576769) failed because I
apparently built the pulseaudio_4.0-6 source, not pulseaudio_4.0-6+b1, and this
has now gotten too deep for me.
