Update 2020-10-10:
I cannot remember where I read this in the documentation and I cannot find it again. For now I'm going to remove this
and see what the feedback from the community is like. If this results in issues we can add it back in again. The idea
is that the closest sample rate natively supported by the backend to the requested sample rate should be used if possible.
