Yes, the whole post (including the wine issue) is a demonstration of 
valid use cases that require latencies that cannot be achieved with 
soxr. In this case, the requested latency ends up being 2 ms, and the 
actual latency oscillates between 3 and 5 ms.

That's in wine. FooBar2000 v1.2 (and not any later version) is good for 
testing DirectSound-related code paths.
