You can create a custom ALSA device by adding an entry to ~/.asoundrc
; that will output to both device at the same time.
You have to keep the following limitations in mind:
-You won't be able to do digital passthrough
-It will be stereo only

At this stage, and in the forthcoming future, Myth can only write to
one audio device at a time and can only manage audio and video sync
with one device.
Managing more than one is actually far from being easy
