Yes. I don't know how to say in english but I'll try :-) -> the power

Yes. I hitted Ctl-C because I don't know how to stop arecord :-)

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.
Yes!. Because I compiled vortex drivers without success.
looks ok.
to use jack you only need "snd", "snd-pcm" and
"snd-ens1370"
Ok.
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)
# ll /etc/asound.state
-rw-r--r-- 1 root root 6381 Sep 14 18:20 /etc/asound.state
now is here :-)
/var/log/boot.0:Thu Oct 16 14:24:13 2003: Starting ALSA (version 0.9.6):

er, isnt this from last week? :-) all looks ok.
oh no! :-)... I expected an error
or something wrong... :-))
one further check: look in /proc/asound/cards
there should be just one card "card0"
# cat /proc/asound/cards
0 [AudioPCI ]: ENS1370 - Ensoniq AudioPCI
Ensoniq AudioPCI ENS1370 at 0x1480, irq 5
and
# ll -d /proc/asound/card?
dr-xr-xr-x 5 root root 0 Oct 30 09:38 /proc/asound/card0/

# arecord -f cd

Recording WAVE 'stdout' : Signed 16 bit Little Endian, Rate 44100 Hz,
Stereo
Aborted by signal Interrupt...
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.
Ok... I'll take a look of arecord documentation, because arecord throw
the data to stdout.
jack:
how often are the xruns? or are they too fast to count?
Intinite times or using
your words: 'too fast to count'.
pls post the first few lines of jack output.

you are running everything as root arnt you?
Yes.
is the kernel compiled with low-latency and preemtible
options?
The kernel is only compiled with low-latency because I can't find
preemptible patch for kernel 2.4.22.
# cat /proc/sys/kernel/lowlatency
1
#
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.
Without running jackd I tried to do that:
# jackrec -f pepe -d 4 0
cannot connect to jack server
cannot connect to default JACK server
jack server not running?
#
but running jackd [with a lot of xruns output in the other console]
I get this error:
# jackrec -f pepe -d 4 0
cannot connect input port jackrec:input1 to 0
# jackrec -f pepe -d 4 1
cannot connect input port jackrec:input1 to 1
# jackrec -f pepe -d 4 2
cannot connect input port jackrec:input1 to 2
[I changed port by hand... because I don't have qjackconnect or
qjackctl, I'll investigate why]
cheers!
