Thanks for the response.

[video at sixcore ~]$ netstat -l -x -p | grep pulse

[video at sixcore ~]$ echo $XDG_RUNTIME_DIR

But it gets weirder.

This is from an ssh session from a fedora laptop client. The server is 
headless (running Fedora 25). If I ssh into the server from chromebook 
OR my android phone - paplay works !! In all cases I'm logging directly 
into the user "video" at sixcore.

pactl from the android phone ssh session:

...........

Not at all like the odd connect I get when I ssh from the fedora laptop.

 From the fedora laptop ssh session:
[video at sixcore ~]$ id video
uid=501(video) gid=39(video) groups=39(video),10(wheel),63(audio)

There is no user 1001. At least not in /etc/passwd.

Very puzzled.
