I'm afraid I don't agree with this point, and don't accept the analogy.

Most network utilities don't let you pick which hardware interface is to be 
used for
communication.  That is different from saying they only function with a 
particular
interface.  The question is, who and what are responsible for the 
determination of
which interface is to be used?

Likewise, many sound utilities assume that some other entity is responsible 
for
picking the sound hardware.

Although some users might want to send one sound stream to one sound card 
and
another to a different card, for my purposes, I just want the sound to go to 
the
*right* device.  At present, making ALSA do this is much more fiddly than I 
would like.

I had to double-check.  In Windows Vista, one must re-start iTunes after
plugging in the USB speakers, before iTunes will send sound to them.

So my suggestion would make ALSA behave at least as well as Vista (except 
that
it has to be  configured once by hand).

OK then.  I'll check if it has been make an official feature request.

Thanks!
