A majority of the sound cards out there do 48KHz well, but not so well on other rates, so defaulting to 48KHz is probably the best choice.
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.
One of the most difficult things is getting 44.1KHz MP3s etc. resampled to 48KHz, but most MP3 playing apps support good resamplers so they can still talk to pulseaudio at 48KHz.
Again, not so true for embedded and burning power on resampling tends not to make people happy.
