Yes I'm adding a call to a deprecated function, but that function is already
used if you look at the code. Because PA_SOURCE_MESSAGE_GET_LATENCY
and PA_SINK_MESSAGE_GET_LATENCY both use that call, I felt it made the
most sense just to use that call directly instead of changing it even more.
Latency in general seems to be a bit of a headache with jack though,
how should the case where you have multiple ports with differing
latency requirements be handled?
