The test is for something EVR does, the fix is for something the session does.
OK, if the problem is you don't want these in the same MR, I can open another one.
If you think the evr test is to complex, I am open to change it to use a minimal sink. But do we even know that all sinks behave the same way with regard to preroll after pausing? If not, then we do need to test every sink.
