I don't think you can use the same pcm name twice in asoundrc.
Redefine this to pcm.cmidmix or such.

You don't need to set anything in the asoundrc to use dmix. Just call:
"aplay -D plug:dmix yourfile.wav".

You're lucky. It shouldn't work with hw:0, unless you card supports
hardware mixing. But if it does, you don't need dmix. I'm puzzled.

Normally (without hardware mixing) you cannot use /dev/dsp multiple
times directly. Only ALSA's plug:dmix device supports stream mixing
outside of sound servers. It should be possible to run OSS
applications with the aoss wrapper on dmix, but somehow I couldn't get
this to work yet.
