hi rene
thanks for the hint. i will follow your advice and post there as well.
however, the reason, why i posted here first, was, because jack works
all well here. i suspect the problem to be on the alsa side, since the
error i get is certainly an alsa specific error, not a jack specific
one. it seems, that i setup everything correctly, since skype(alsa) ->
jack plugin -> jack works fine.
since i know, that flash is not going to have native flash support soon,
i am trying the alsa jack-plugin way and that is what i have troubles
with at the moment (and would like to make work). therefore i still hope
to rather get a meaningful answer here than from jack list.
cheers
roman
