Textual MUAs aren't outside possibility.

Good.
Meanwhile,
peter@joule:/home/peter$ aplay -L | grep dmix:CARD=L
dmix:CARD=Live,DEV=0
dmix:CARD=Live,DEV=1
dmix:CARD=Live,DEV=2
Try the second DEV,
AUDIODEV=dmix:CARD=Set,DEV=1 play MY/m85.WAV
ALSA lib pcm_dmix.c:1108:(snd_pcm_dmix_open) unable to open slave
play FAIL sox: Sorry, there is no default audio device configured
And the third,
AUDIODEV=dmix:CARD=Set,DEV=2 play MY/m85.WAV
ALSA lib pcm_dmix.c:1108:(snd_pcm_dmix_open) unable to open slave
play FAIL sox: Sorry, there is no default audio device configured
No option to list _configured_ devices? Maybe refer to /proc/asound/Device/.

"dmix:CARD=PCH,DEV=0" could be a name in a hardware manual
published in 1970. I'd still prefer to call a USB headset "USBheadset".

Installed it but don't see how it facilitates a text
command to play a WAV.
Thanks for the reply, ... P.
