This really isn't so true in the embedded space, there's a few systems
that only do 48kHz to the AP but generally if there's a fixed sample
rate it'll usually be 44.1kHz and otherwise the rates will be flexible.

Again, not so true for embedded and burning power on resampling tends
not to make people happy.
