I only have one sound card in the PC.

It works fine when I start PulseAudio in the system mode, but according 
to documentation, this is unsupported, strongly discouraged and should 
only be used in some embedded setups.
So I'd like to do it "the right way" - unfortunately, PulseAudio 
documentation does not explain how to setup PulseAudio with multiseat.

If I start PulseAudio in the user mode, only one user gets a sound card; 
the second one gets "Dummy Output".
