[pulseaudio-discuss] container support

This can be achieved fairly "simply" (as long as you know what to look for).

You need to pass the pulse socket into the container and tell pulse 
clients inside the container its precise path.

So on Docker CLI, for a typical Pulse daemon running in userspace, it 
would be something like:

*|-v /run/user/1000/pulse:/run/user/1000/pulse |*

Inside the container, once you've installed Pulseaudio, you need to 
modify its client configuration:


*default-server = /run/user/1000/pulse/native*

With this your Pulseaudio applications should be able to play sounds 
through the host PulseAudio server (of course, you'd need to adapt the 
runtime paths to your environment).

Bear in mind, there seems to be some inconsistencies in the way various 
Pulse utilities interface with the daemon. In this setup for example, 
"pacmd" won't work, whilst "pactl" works fine once the client 
configuration is fixed.

You could test this in a manual way first and then automate things a bit 
with a Dockerfile and what not.

Best regards.
