There is another solution, copy the following to a file
called .asoundrc in your home directory:
pcm.!default {
type plug
slave { pcm "jack" }
}
pcm.jack {
type jack
playback_ports {
0 system:playback_1
1 system:playback_2
}
capture_ports {
0 system:capture_1
1 system:capture_2
}
}
ctl.mixer0 {
type hw
card 0
}
Then start mplayer without the -ao jack. It should then
use the default ALSA card which we redefined to be a
virtual one connecting to Jack.

Tried several. Currently:
jackd --sync -dalsa -dhw:8
hw:8 is definitely the Multiface. aplay -D plughw:8 plays there just
fine.
After having started Jack, in another terminal, run
jack_lsp
which should produce a list of Jack ports for your Multiface.
I you have that it means Jack is definitely running OK.

Glad to
hear. I have no desire to run as root, just that some on line docs
I found seemed to suggest running as root.
Trying to start jacd from the command line as
root I fail for lack of an
X-server.
Unlikely, Jack doesn't need X. But you shouldn't run it as root. Starting as my ordinary user I get:
What options do you use ? You'll need at least something like
jackd -d alsa -d hw:NNNNNN
mplayer -ao
jack <filename>
Strangely, this gives me:
No such audio driver 'jack'
Could not open/initialize audio device -> no sound.
This is stock rpmfusion build of mplayer 1.1 for Fedora 20 (x86_64). I'm assuming
they include jack support in their build?
