[pulseaudio-discuss] --check option seems not to work from su(1) as daemon user

[Glenn Golden]

Not sure if this is a bug or braindamage on my part. In view of the doc
for the "--check" option, I was surprised at the following:

As ordinary user 'gdg' (under which PA daemon is running):

    $ id
    uid=501(gdg) gid=501(gdg) groups=501(gdg),19(log),92(audio), \
	190(systemd-journal)

    $ pulseaudio -v --check
    I: [pulseaudio] main.c: Daemon running as PID 23204

But as root, do "su - gdg", then 

    $ id
    uid=501(gdg) gid=501(gdg) groups=501(gdg),19(log),92(audio), \
	190(systemd-journal)

    $ pulseaudio -v --check
    I: [pulseaudio] main.c: Daemon not running


Why?
