HDMI auto volume control

[oldmercman]

I just installed my second Aftermaster Pro .....this unit will not pass a 4k signal ( same as the first unit.....which lasted about a year) up graded my Roku unit to get additional channels.
I tried a Newell downscaler unit between The new Roku and the Aftermaster unit.....won't work. I 'd really like to find a mutiple/switchable HDMI auto volume control for TV, Blue Ray and Roki units. I have a Yamaha multiple input 6 speaker surround system, 120hz Samsung Led TV......cable box is Xfinity(Comcast).....HAPPY WITH IT ALL.....but the varying volume levels is driving this 72 year old dubber crazy....Any suggestions appreciated.....thanks.
