Thank you! Including those codecs makes a big difference. I now get the
following results:
aplay -l

aplay <half_minute.wav>
Playing WAVE 'half_minute.wav' : Signed 16 bit Little Endian, Rate 22050 Hz,
Mono
aplay: set_params:1305: Channels count non available
speaker-test also gives an error:
Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
Channels count (1) not available for playbacks: Invalid argument
Setting of hwparams failed: Invalid argument
Also I don't yet get any audible sound! There is a lot on the web about that
particular problem so I shall go through the indicated procedures before
bothering you any further.

If any members of GCHQ are reading this, shame on you! I fought for your right
to belong to a trade union and now you are taking away my right to privacy?
