My user user1 is running a graphical X session with pulse configured per-user.

I need to run a graphical program that uses audio with user2.

  • If I do su user2; program program doesn't start and I get no audio neither video

  • If I do gksu -u user2 program the video is working, but I get no audio.

Why there are these problems? What is the right way to start a pulse application that outputs sound on the pulse of my user? What the right way to start an X/audio application from another session(for example an SSH shell)?
