That was it! arecord didn't record anything, so the problem was on the
ALSA side.
But now that that part is fixed  there's a new problem: I get a lot of
hiss when I connect the capture ports to rakarrack's input ports. I
muted almost everything in alsamixer, but that didn't help. It's as if
rakarrack's output were connected to its input - but it's not. Maybe
now I'm indeed facing a jackd (or a rakarrack) problem...

These things happen, I know... but probably not this time.

I learned now that alsamixer had more controls (activated by TAB) than
what can be seen by default.

Thanks a lot!
