whoa.  firefox has a manpage?  who knew?  ;-)

i'm not sure i understand this.  what _is_ the /dev/dsp wrapper that
they're talking about?  is "audio_oss" a dsp wrapper?

i found a reference on the web to setting it to "aoss" (not mentioned
above in the man page).  not sure what it would do.

in any case, setting FIREFOX_DSP to "none" or "aoss" doesn't
help.  of course, there are so many pieces of the chain that
could be misconfigured that it's a little hard to say for sure
what might or might not work.

okay.  i'm not sure i have time right now, but i clearly have the
need.  i'll either pursue this on my own, or try to talk it up on the 
alsa list.  (of course, if anyone on this list has alsa skills and can
point me in the right direction...)
