What exactly do you mean by proportional control of volume level with remote?

@@drrckhamilton It's a bit complicated, but my setup has no control for volume other than the ACR knob. That's because my source input is SPDIF from the OEM head unit which contains no volume data. Since I rely entirely on the ACR knob for volume control of my system, I need AudioControl's firmware to be able to control each channel output in a proportional way. As it's designed right now, if you have all your outputs to be controlled via the ACR knob, and you turn the knob, each channel gets raised or lowered by 0.3db. This causes some buggyness when lowering the volume to the minimum and bringing it back up with the knob. When the knob is used to lower the volume to the lowest level, all the channels drop the same level, overwriting any per-channel gain I have in the DSP until it's rebooted. Basically, my sub channel, and my door speaker channel will have the same pre-set gain when I bring the volume up.

@tylerwatt12 Thanks for responding. I am wondering if this would be a problem for me as my intent is to use a high-resolution music player out of the coaxial input, and I know that typically you are unable to control the volume from the head unit when connected to coaxial. I would also like to be able to change inputs if possible.
