How to use both analog and HDMI audio out with SDL/alsa?

Is it possible to do that with SDL (1.3) ? Previously I was using
pulseaudio but its too buggy and hectic to configure so I am giving
alsa a shot. I am using the environment variable AUDIODEV to setthe
alsa device
(plughw:0,7) but I also need to send the same audio data to plughw:1
(analog audio out / pcm), how do I do that? These two works perfectly
fine with speaker-test.

Thanks for any input.
