This is a highly specific question and is unlikely to be documented. I’m
curious why you’re interested.
At the end of the day, the audio hardware operates at some particular
bitrate, so unless your source exactly matches the hardware sample rate
there’s likely to be a SRC in the audio pipleline *somewhere*.
