This was the first thing I tried.  It didn't work.

Not really.  apulse messes with LD_LIBRARY_PATH so that its arguments 
see a "fake" libpulse.so which acts as a pass-through to ALSA.  This is 
supposed to work in some fashion, but it didn't for me.  I think this is 
actually because on Gentoo, apulse and pulseaudio cannot be installed at 
the same time.  Also because there is apparently a thing you have to do 
that was never explained properly in the documentation that I read:  You 
have to do "patchelf --set-rpath /usr/lib64/apulse 
/usr/lib64/firefox/libxul.so" (or wherever your libxul.so file is.)

I'd try this, but everything works properly now and rebuilding firefox 
takes 2 hours.
