After having started Jack, in another terminal, run jack_lsp which should produce a list of Jack ports for your Multiface.

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. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
