Hi,
My Volumite controller chip works only in "stereo mode".

Without Volumite, I can sucsessfully select "stereo mode" "(dual)mono mode" with on-board controller.

With Volumite, "stereo mode" and volume controling are no probrem, but I cannot enter "mono mode".
Volumite controller chip ignores dip switch on/off.

* Of course I2C header is connected, PB1 is connected to GND and DAC's on-board controller removed.

Any solutions? or my Volumite controller chip itselves have problem?

Solved.
I'd forgotten jumper ADDRESS, and my major fault was I was too lazy to wiring between dac-volumite and setting dip switches WHILE DACS ARE RUNNINGd'oh!

Feeding power to the dacs after correct wiring and dip switch settings, they start running as dual mono mode correctly.

I have one IVY III module and one another I/V conversion board, so I had tested dual mono mode using IVY III by simply
pararelleling R+/L-, R-/L+ on each Buffalo II.
