As you trimmed the output we dont know what other hardware could be causing
problems, but still, it looks ok.
so which card are you trying to use? the ensoniq i guess.

looks ok.
to use jack you only need "snd", "snd-pcm" and "snd-ens1370"

ok, no problem. Module info is more useful anyway.

looks probably ok.
probably you havnt saved your mixer settings?
they live in /etc/asound.state (or your home dir)
you might want to create one using the alsactl program as root.
(i dont know why disributions dont do this as part of the alsa installation)

ok.
all looks ok.
one further check: look in /proc/asound/cards
there should be just one card "card0"

i originally thought this was an error but i guess it is just
you hitting Ctl-C.
it looks like alsa is not the problem, but before moving onto jack
maybe it would be wise to check recording from the soundcard input
rather than stdin.
jack:
how often are the xruns? or are they too fast to count?
pls post the first few lines of jack output.
you are running everything as root arnt you?
is the kernel compiled with low-latency and preemtible options?
maybe dont start with ardour as its undergoing rapid development
atm. Better to imo use eg 'alsaplayer -o jack'. Also use one of
the jack control guis such as qjackconnect or qjackctl to check
jackd has 2 input ports and 2 output ports.
cheers!
