Getting jackd to output sound ?

Hello,

here is my situation :
* Raw ALSA (no pulseaudio installed) works, e.g. `aplay foo.wav`.
* Pulseaudio works.
* jackd does not work, as in : it starts and runs (I can check for instance signal going through by using vumeters), but I get no sound out of my loudspeakers while using jack_metronome, vlc, hydrogen, whatever...

Here's what aplay -l gives :

**** Liste des Périphériques Matériels PLAYBACK ****

and aplay -L :

I tried running jackd without pulseaudio installed at all, or with pasuspender -- jackd but it does not work in either cases.

I've tried

jackd -v -r -dalsa -dhw:0,0  -Xseq
jackd -v -r -dalsa -dhw:0,1  -Xseq
jackd -v -r -dalsa -dhw:1,0  -Xseq
jackd -v -r -dalsa -dhw:1,1  -Xseq

and also explicitely setting a sample rate (-r44100, -r48000) and a buffer size (-p64 to -p512), but to no avail.
Also tried qjackctl, which did not give anything either.

My volumes in alsamixer are all to the top.

Have you made sure they are using jack when they are playing stuff though? You can check with:

jack_lsp -c

I'm pretty sure: they appear in the qjackctl patchbay and I can connect them together. For instance connecting the metronome to the vumeter shows that there is indeed something playing; I just can't hear it...
