that's ok, since there is no master connected to it just yet. so it
hangs in the driver creation phase.

that is weird. jack_netsource is just another jack client that shouldn't
talk to the hardware directly, but to your master jackd. maybe it
doesn't see the real master jackd and tries to spawn a new one, which
would explain the error message.

as i said, jack_netsource does not use a hardware backend, it talks to
jackd only. the fact that you're seeing this error seems to indicate
that there's something wrong with your jackd. can you connect other
clients? do you see your hardware ports when running jack_lsp?

that's it. you need to make sure you compile the alsa backend in.
if you're using alsa packages from your distribution, make sure you have
the relevant -devel ones installed as well.
then go back to the jack sources, "make distclean", "./configure
--prefix=/usr [--enable-optimize]", rebuild, reinstall.
