My goal is not to make my driver passing all the tests. Instead, I
want to report that some tests behave strange (at least) or are buggy
(at most). WLK tests are not applications provided "just for fun" but
are used to test all drivers submitting to WHQL certification. So
these important tests must be EXTREMELY correct. If some tests fail
with several correct drivers, there is a high chance that they may
pass with an incorrect driver. Since most audio driver developers
don't create their drivers from scratch, modifying WDK samples
instead, hundreds of various drivers might have WHQL signature but
still be buggy.
