As far as i understsnd the sources you must prepare your device to
interpret ALSA_PCM_DEVICE. Try /etc/asound.conf as follows:

defaults.pcm.card 0
defaults.pcm.device 3
defaults.pcm.device {
    @func igetenv
        vars [ ALSA_PCM_DEVICE ]
        default 0 
}

Now it should be possible to run
$ ALSA_PCM_CARD=1 ALSA_PCM_DEVICE=0 mplayer test.mp3
