Can't help but can tell you I have the exact same problem! I also don't
get audio from streaming media directly from the internet (eg a web
hosted .ogg) Have you managed to get that working? I use VLC's
Multimedia Plugin for firefox, VLC is set to Jack, also have all
GStreamer routed through Jack, but "normal" firefox audio never reaches it.

Good luck with this one. It's part of the reason Arch is feeling so
appealing to me right now. I can truly get a system with no P(IT)A in
there! ;-)

Dale.
