I was reading

http://petertodd.ca/hdsp.php

and the only place it mentioned 24 bit was down toward the bottom,
implying that it wasn't supported. But now that I know it is and looking
through the source for jack, it would appear that by default, it will
open the device in 24bit mode, that's good. It would appear that as
opposed to most other drivers, I shouldn't be using dithering on this
device as I'll loose my dynamic range, yes? (I noticed your name all
over the code, so I'm betting your probably the best to ask this
question...)

d!
