Installed a roku 4800 Ultra in my Tiffin Motorhome through a 4 way splitter/amplifier and have beautiful pictures throughout the 4 tvs but no sound. If I hook the roku to splitter and one tv I have sound but as soon as I have added other TV the sound disappears. I have the Roku set to passthrough with no change.
The splitter is triplevision 4k 3 years old.
Thanks for the post.
If you are not experiencing an issue with the device connected with just one TV connected, it would seem that the issue would be with the splitter.
Thanks,
Danny
