Sorry... I suppose the output could be too long to post here.

Yes!. Because I compiled vortex drivers without success.

Ok.

Yes. I don't know how to say in english but I'll try :-) -> the power
company leave the city (this day) without power for political reasons.

oh no! :-)... I expected an error or something wrong... :-))

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

Ok... I'll take a look of arecord documentation, because arecord throw
the data to stdout.

Intinite times or using your words: 'too fast to count'.

Yes.

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

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]
