[clue-tech] Alsa dmix output to 2 cards simultaneously

[Dave Price]

Cluebies,

I can't seem to find any specifics on this ...

I have two sound cards working under ALSA through dmix.

I can specify a default dmix, or send a specific program to one card
or the other, but I have not yet figured out a dmix configuration to
let a single program send it's output to both cards at once.

(The cards are connected to amplifiers/speakers in different parts of
the house.)

Any suggestions on the right dmix syntax to use for such a 'virtual'
device would be appreciated.
