Yes, as far as all involved apps ask for the save "basic"
parameters: sample rate and number of channels.

Well, perhaps I'm missing the point, but I don't see why
applications should be able to use the same hw stream at
the same time if the hw doesn't support mixing. The
result would not be what the user expects.

IMHO alsa should use dmix by default, unless the
application explicitly asks for bypassing it.
