For IRIX compatibilty, we may want to implement the same interface as
IRIX has. But for Linux compatiblity we should have something, which fits
into the current Linux sound devices scheme. And as the Linux interface is 
available in source, I would go that way. And when you do the libaudio.a 
stuff based on the Linux sound devices, it will also be available for other 
Linux architectures.

Maybe it's even possible to get IRIX compatible sound, with a user level
only solution.


See, you not only have to be a good coder to create a system like Linux,
you have to be a sneaky bastard too ;-)
