[pulseaudio-discuss] Hide a soundcard from pulseaudio?

[tomhorsley at comcast.net]

I've got two soundcards, one I want pulse to use, one I want
dedicated for mplayer to use for spdif passthrough. What is
the best way to hide a soundcard from pulse?

My current theory is to not use the udev module and instead
explicitly list just the modules for the audio devices I
want it to use, but I'd prefer a better way.
