Regret to say still no response:

aplay -Dplug:dmix Any_Dream_Will_Do.wav
ALSA lib pcm_direct.c:741:(snd_pcm_direct_initialize_slave) unable to
install hw params
ALSA lib pcm_dmix.c:728:(snd_pcm_dmix_open) unable to initialize slave
aplay: main:508: audio open error: Device or resource busy

Perhaps I misunderstand .asoundrc? Since that's very possible, I'm
attaching my current. Works to play directly and via spdif, but not
dmix
Thanks.

If Linux can't solve your computing problem, you need a different problem.
