Log Message:
Explain the format of the raw PCM data users can read from a pad(4).
Since it's headerless this is important so the data can be interpreted
properly. Also, ordinary audio ioctls cannot be used on a pad and the
format can't be changed, so applications that attempt to automatically
determine the format of a device like audiorecord don't work.
