Trying again today, I've found a command that works:

   play.exe -n -c1 -t waveaudio synth sin %-12 sin %-9 sin %-5 sin %-2 
fade h 0.1 1 0.1


It doesn't work with   -t waveaudio 0
                   or   -t waveaudio 1
                   or   -t waveaudio -1


If I ask sox to be very verbose ( -V6 ) in the command that works, ie by

   play.exe -V6 -n -c1 -t waveaudio synth sin %-12 sin %-9 sin %-5 sin 
%-2 fade h 0.1 1 0.1

some of the verbose output says:

   play.exe DBUG waveaudio: waveOutOpen(QUERY: Dev -1 48000Hz 1Ch 32Prec 
32Wide) returned 0
   play.exe INFO waveaudio: Using default output device at 48000Hz 1Ch 
32Prec 32Wide.

which is interesting because the "waveOutOpen(QUERY: Dev -1" part 
suggests that internally
sox was able to find out what the 'default' device was by referring to 
device id -1, this
time, but in stuff I did yesterday it kept showing

  sox.exe DBUG sox: Looking for a default device: trying format 
`waveaudio'
  sox.exe DBUG waveaudio: waveOutOpen(QUERY: Dev -1 0Hz 0Ch 8Prec 8Wide) 
returned 32

where the same device number didn't seem to work.


I also found a way to make sox show me what devices it was considering 
when looking for a
default waveaudio device.  By telling it to show me lots of debugging 
output (with -V6) &
asking for a named audio device that it won't find

  sox.exe -V6 -n -t waveaudio jfhgfgfjg

some of the output contained:

  sox.exe DBUG waveaudio: Enumerating output device -1: "Microsoft Sound 
Mapper"
  sox.exe DBUG waveaudio: Enumerating output device  0: "Speakers (USB 
Audio CODEC )"
  sox.exe DBUG waveaudio: Enumerating output device  1: "Speakers 
(Realtek High Definiti"
  sox.exe FAIL formats: can't open output file `jfhgfgfjg': The requested 
WaveAudio device was not found.

So... you'd think if it lists three named devices, one should be able to 
specify any
of those by name?  But I was not able to do that:

  C:\>play.exe -V6 -n -c1 -t waveaudio "Microsoft Sound Mapper" synth sin 
%-12 sin %-9 sin %-5 sin %-2 fade h 0.1 1 0.1
  play.exe DBUG sox: Looking for a default device: trying format 
`waveaudio'
  play.exe DBUG waveaudio: waveOutOpen(QUERY: Dev -1 0Hz 0Ch 8Prec 8Wide) 
returned 32
  play.exe FAIL sox: Sorry, there is no default audio device configured

  C:\>play.exe -V6 -n -c1 -t waveaudio "Speakers (USB Audio CODEC )" 
synth sin %-12 sin %-9 sin %-5  sin %-2 fade h 0.1 1 0.1
  play.exe DBUG sox: Looking for a default device: trying format 
`waveaudio'
  play.exe DBUG waveaudio: waveOutOpen(QUERY: Dev -1 0Hz 0Ch 8Prec 8Wide) 
returned 32
  play.exe FAIL sox: Sorry, there is no default audio device configured

  C:\>play.exe -V6 -n -c1 -t waveaudio "Speakers (Realtek High Definiti" 
synth sin %-12 sin %-9 sin  %-5 sin %-2 fade h 0.1 1 0.1
  play.exe DBUG sox: Looking for a default device: trying format 
`waveaudio'
  play.exe DBUG waveaudio: waveOutOpen(QUERY: Dev -1 0Hz 0Ch 8Prec 8Wide) 
returned 32
  play.exe FAIL sox: Sorry, there is no default audio device configured



I also found in a MSDN programmers' info page:

https://docs.microsoft.com/en-us/windows/win32/cimwin32prov/win32-sounddevice

a way of listing audio devices on my pc.   When I run something based on 
that
I see three devices, but I don't see the names that sox was able to 
find.  I
see:


1)      Caption: Realtek High Definition Audio
     Description: Realtek High Definition Audio
        DeviceID: 
HDAUDIO\FUNC_01&VEN_10EC&DEV_0269&SUBSYS_144DC0D8&REV_1002\4&1391229C&0&0001
    Manufacturer: Realtek
            Name: Realtek High Definition Audio
     PNPDeviceID: 
HDAUDIO\FUNC_01&VEN_10EC&DEV_0269&SUBSYS_144DC0D8&REV_1002\4&1391229C&0&0001
    Product Name: Realtek High Definition Audio
          Status: OK
      StatusInfo: 3

2)      Caption: Intel(R) Display Audio
     Description: Intel(R) Display Audio
        DeviceID: 
HDAUDIO\FUNC_01&VEN_8086&DEV_2806&SUBSYS_144DC0D8&REV_1000\4&1391229C&0&0301
    Manufacturer: Intel(R) Corporation
            Name: Intel(R) Display Audio
     PNPDeviceID: 
HDAUDIO\FUNC_01&VEN_8086&DEV_2806&SUBSYS_144DC0D8&REV_1000\4&1391229C&0&0301
    Product Name: Intel(R) Display Audio
          Status: OK
      StatusInfo: 3

3)      Caption: USB Audio Device
     Description: USB Audio Device
        DeviceID: USB\VID_08BB&PID_2902&MI_00\7&173E1977&1&0000
    Manufacturer: (Generic USB Audio)
            Name: USB Audio Device
     PNPDeviceID: USB\VID_08BB&PID_2902&MI_00\7&173E1977&1&0000
    Product Name: USB Audio Device
          Status: OK
      StatusInfo: 3

which is not helpful.  For a start the device numbers -1, 0, 1 don't 
seem to
correspond.

When I use the Control Panel - Sound configuration options, it shows 
devices
with names like "Realtek High Definition Audio", "USB Audio Device" etc 
which
correspond to the ones in this list.  But the names are not precisely 
the same
as the enumerated names that sox showed when trying to make sense of 
jfhgfgfjg.
