that could actually be the problem. there really will be no proper support
forum for that, and that is the challenge. the reason we have the jack dbus
is to route traffic from pulse audio to JACK, which i think is great for
users who need this. i personally appreciate the work that has gone into
providing this feature, but, disable it first thing, since i dont need it.
when i need audio from the web, i *dont* also need JACK running. the main
issue with this is, JACK *is* open.. so *any* and all web browser are free
and welcome and encouraged to write JACK support into their products.. the
creators of flash and html5 specs and content are welcome to cater to JACK
as well. they can also write for and test pulse audio support. but, taking
some content that is not designed to do what you are trying to do will
likely have some compromises.. i would say, if you dont need pulse content
through jack, just stop jack, and use the web content as it has been
designed to be used.. if you need JACK, then, you can try and work with
normal bug reports, but i would go as far upstream as possible..

cheers, and good luck!
