Title: RGBW model EQ for auto "direct sound"

I have played a bit with the RGBW idea. And the result is really nice.
I am not sure if it is worth merging, because currently an additional buffer mix step is required.
But I am sure this makes High-End HiFi users happy.

On my system there is a notable sound difference once I touch the EQs the first time. It sound not "bad" after EQ is enabled, but the untouched samples sound is the desired sound without a doubt.
This patch bypasses the EQ when all eq knobs are at the same position.

What do you think?
