Absolutely, but just because a thing CAN be done does not mean that it
SHOULD be done. USBAudio.sys works, and keeps getting better with each
release. Surely it already does 90% of what the original poster
wanted. Given that, it is a waste of resources to throw out all of that
proven and working code and start over. Instead, leverage what already
exists, and add your customizations as a filter driver or as a ksproxy
plugin.
