By running "gnome-control-center sound" I can get a GUI app in which I can set a device profile to "off" so that pulse will stop fooling with it, and I am then free to talk to it directly with alsa to do special things like ac3 passthrough to spdif.
My question is: Can I do the same thing with a command line tool so I can modify the pulse settings in scripts and set them back to normal after (for instance) playing a DVD?

I think you're looking for "pasuspender" which will suspend pulseaudio until whatever you run completes. The usage is a bit odd. I use it for "The Dark Mod" (a Thief fan game based on the Doom3 engine). In my launcher script I use it as follows:
pasuspender -- ./tdmlauncher.linux
The double hyphen is important!

That would probably work, but I finally searched for the right phrase and got a hit on "pacmd". Looks like I can feed it commands to set the profile of some card to "off" so I can use that card for other things for a while.
That's less drastic than completely turning off pulse (but time will tell if it works as well :-).
