The D1/DX hardware doesn't have that many controls because there
aren't so many inputs or outputs.

There is one "Master" control with 8 channels.  How this is displayed
is up to the mixer application.  (alsamixer isn't ideal in this respect,
older versions even less so.)

Yes, the driver now doesn't write registers that have not changed.
In theory, this shouldn't make too much of a difference unless the
mixer tries to set the same volume repeatedly.
