Thanks for the suggestion.  This gives the same 'non available'
error as above.  Maybe these aren't recording aliases?

Contents of 'arecord -L' are attached.

I've just confirmed that an analogue loopback recording works
if -D is not specified, whereas -Dhw:0,0 (which I think should
be the analogue device) gives the 'non available' error.
