OK. Salsa is performing the same as asound using "hw", except one other 
perhaps trivial thing I have noticed.  The aplay code does
	err = snd_output_stdio_attach(&log, stderr, 0);
and prints things
	snd_pcm_hw_params_dump(params, log);
finishing with
	snd_output_close(log)
In alsa-lib, the third parameter of .._attach is used to set 'close', and 
being 0, means stderr is not closed.  However, with salsa the file is always 
closed at the end.  I am using the aplay code as a function, and on the 2nd 
call, there are non of the print items.  Preventing this close in salsa or 
the aplay code does remove the problem.  Is this intended trimming of 
functionality for min size?

Ultimately though, I can live with this.

I will continue the configuration discussions with a different title (since 
not salsa-related).
