Avoid ALSA devices exclusively used by Pulseaudio?

[ml@xxxxxxxxxxxxx (Rene Bartsch)]

Hi,

Pulseaudio shall detect pluggable ALSA devices but shall ignore 3 
specific devices to keep them free for other applications (BruteFIR).
In other words, how can I tell PA not to use "hw:FCA610", "hw:Intel" and 
"hw:Speakers" but anything else?
