The probably easiest way to do this would be to use a sound server like
pulseaudio. It can create a stream to all cards installed on your
system. Pulseaudio can be found in most distribution repositories. It
can be configured easily and also works with most applications. A setup
and configuration guide can be found here:

[Alsa-user] Trying to use two sound cards at the same time
Hello
I have two sound cards, one attached to pc speakers and one attached to a
sound system in another room.
Following instructions on the alsa project wiki, I am trying to use two
sound cards (V8237 and CA0106).
I configure my ~/.asoundc but I still can't manage to send a sound to both
cards at the same time. Below is my ~/.asoundrc content.
When I tested directly the ca0106 card (hw:0,0) with a play, it didn't work
so I thought it might be some sort of rate or conversion problem. I added
the pcm.via and pcm.audigy in my asoundrc file and then, when I test each
card individually (via and audigy) with aplay it works well.
When testing the multi pcm with aplay ( aplay -vD multi question.wav ), I
get the following error
aplay: set_params:959: Nombre de canaux non disponible (Channels count non
available)
