Mostly only for compat cases it makes sense to let the application choose the device itself. It has been requested before that PA provides ALSA enumeration for all the devices it covers. I'd be willing to bless a clean patch for that for alsa-plugins, however personally I'd rather invest the time in fixing the apps in questions to tag their streams properly so that PA can distuingish them than to work on this workaround.
