Extra information: I've run up YouTube with the virtual sound card set 
to ac97 and can play back a simple audio stream.  Running the MIDI 
system has no effect.  Furthermore the mixer shows a connection from 
Firefox, but doesn't show one from Frescobaldi.

I think you've hit the nail on the head.  Well done.  Now how to fix it!
