    Get some RCA Y-splitters to feed both signals.

    There may be some conflicting settings in your ALSA configuration files.

    My application is a bit different than yours, and I'm not done with my research yet. Just wanted to point you to this for info only:

    Just as an update to others, here is a solution. If you are running Ubuntu Natty: you can simply install "paprefs" through System-->Administration-->Synaptic Package Manager which will give you the easy to use PulseAudio Preferences GUI. It let's you combine all sound cards together into a combined output device which you can then select as your default output in order to have sound sent to all devices. As another benefit, it allows you to share your audio over the network. This is just a front-end to modify the /etc/pulse/default.pa config file, but it's quite convenient.

    Hope this saves someone else some time.
