thats an interesting question. a rather hard to answer one. what we
could do is this: make jack open "hw:0,0" as the default device rather
than "default". this would then bypass the alsa-lib plug device, and
force the user to deal with the actual hardware. there is some merit
to this, since in a JACK system, none of the clients care about this
stuff.
i think alsa-lib's use of the plug layer for "default" is a good
choice - it means that you can play or record in just about any format
from this device. but since JACK is in some ways providing similar
functionality through a rather different design, it seems foolish to
try to do this twice ...
anyone have any thoughts on this?
