I haven't set a shell.  According to https://wiki.debian.org/Shell 
it's bash.

Now that there is only one internal sound device this seems right.
play a42.WAV

If the sound card is replaced, will try this sort of thing.
setenv AUDIODEV=plughw:CARD=ICH5,DEV=0 ; play a42.WAV

with present /dev/ names I guess something similar to this is out of 
the question.
sox a42.WAV /dev/snd/blaaaa

Device names are used for storage devices and for network adapters.  
Why not for sound devices?

I expected to find relevant examples in a manual page or wiki page.  No 
such luck. Sorry to repeat but documentation needs attention.

Thanks,                       ... P.
