[lxc-users] Graphics and sound with LXD

     I know it has been a while since I brought this subject up as I 
have not really made any progress since. I did have success mounting the 
appropriate audio devices in the container just as with the legacy lxc 
technique but the privileges issue seem insurmountable, at least for me, 
as there does not seem to be a method to import a host uid into the 
container with lxd.
     That being said it recently occurred to me that there was another 
method that seems simpler and more elegant for this use case and that is 
exporting pulseaudio server over the network. It is fairly well 
documented, although unfamiliar to me, and I have been experimenting 
with it. It seems to be working on the host side but the issue arises in 
the container. Pulseaudio is installed but seems detached. When I launch 
an application all seems to go well and no more errors about missing 
sound devices but no sound. And there is no pulseaudio instance launched 
in the container. Attempts to connect with pulseaudio simply time out 
with no other errors.
     Any ideas? Is this doomed to fail in this use case for reasons I am 
unaware of?
