I have these in my set up: Yamaha RX-A780, Samsung TV model UN55MU630D, Roku ultra 4800R device.
My original Roku died and I installed the 4800R to replace it. Figured out how to get the center channel working, but the sound level is a good 10-15 points below the previous setting.
I use two bookshelf speakers and a center speaker everything worked fine before.
Under settings/audio/streaming audio format I have audio set on auto. For the next category settings/audio/digital output format I have it set on stereo. I tried pass through and the center channel works on both, but the volume level is the same for either.
I have leveling on under options, but I do not have the AC-4 on since I am on stereo.
Firmware was updated when I installed the unit and is current.
Is there a solution or fix for the low volume vs the previous model? No set up I have tried solves this problem.
