deckoff the curse of pulseaudio. Reason why you were getting no sound is the pulseaudio sound server is still sitting on the audio in an exclusive way. 3 possible solutions. 1 don't use pulseaudio return to dmix and alsa. 2 use pulseaudio but have dmix under it that everyone can access. 3 Do some horrid setting to pulseaudio so that the second users audio can pass into pulseaudio of the first user. Anyone one of the 3 you don't loss sound when you switch between sessions. This is something I want pulseaudio to fix assp. Some way to allow pulseaudio servers to operate nicely with each other.
