I expect Ben will post a proper interim and full disclosure on Monday. The issue is not related to ALSA at all.
The problem here was that some unfinished development-code made it into the Mixbus Linux releases (3.1.716), not present in the Windows, OSX 3.1.713 binaries.
Many soundcard do have a hardware mixer, inside the soundcard.
ALSA -- the Advanced Linux Sound Architecture -- is the kernel driver for soundcards [1]. It exposes Audio, MIDI and Mixer. Jack does not concern itself with the soundcard's hardware mixer.
The purpose of JACK is to allow inter-application routing: Connect outputs of one JACK application (e.g. Hydrogen) to inputs of another JACK application (e.g. Mixbus). On Linux, JACK also uses ALSA under the hood to interact with the actual hardware.
[1] ALSA also includes some user-space part for configuration.. not really relevant, but mentioned for completeness: it's not kernel only.
All in all this is pretty much the same on other OS. The hardware mixer is usually separate and for most soundcards there's even a dedicated HW-mixer application to control routing or volume levels inside the soundcard.
