Awesome, thanks for the fix! I applied it to the "next" branch, so it won't be
in the next release (we're in the freeze phase), but it will be in PA 12.0.

There's a problem with integer overflowing, though. pa_usec_t is an unsigned
type, so I don't think it's a good idea to store negative values in it (even if
it seems to work pretty well). I tried to fix it, but when I tested my fix, the
results were worse. My fix included changing the code so that if the latency is
negative, pa_simple_get_latency() returns zero (because it doesn't have a
mechanism for reporting negative latencies), and it looks like
pa_stream_get_latency() is reporting negative latencies even when it should
have no reason to do so, and I'm trying to figure what's going on.
