Now I have this:

for i in `seq 16`
        ecasound -f:32,2,48000 -a:ch$i -i jack -o ch$i.wav
-G:jack,ecarec_ch$i & sleep 1
        jack_connect alsa_pcm:capture_$i ecarec_ch$i:in_1
        jack_connect alsa_pcm:capture_$i ecarec_ch$i:in_2

I can see in qjackctl that connections are properly set up. The jackd
is running. However, when I click the play button ('start transport
rolling'), the green text blinks 'Starting' for a moment and goes back
to stopped immediately. I guess this narrows down my 'not recording'
problem to jack. How can I debug it? Running it with -v does not give
any clues ...
