From the same file:

Which is part 1 of my point -- unless Jack promises *never* to change
this scaling strategy, it should be available for those apps that need
bit-exactness.

Part 2 of my point was: can I find out whether Jack is reading 16-bit,
24-bit, or something else from ALSA? There's no point in wasting disk
/ memory space if I want to convert back to PCM in my app.
