"At a certain point". Do you really want to arbitrarily be able to direct
the sound from one to two speakers?
I have no idea what software would do that. Now it probably would not be
hard to write a little program with an X interface which, when you press =
a
button would direct the sound eitehr to one sound card or to two of them.
But I do not know it. That does not mean much as there is a huge amount I
do not know.
