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!
