Updated 4k boxes with dual hdmi outputs
I have a interesting issue. I have an older onkyo audio receiver that has dolby truhd capability. It does not, however support 4k resolution. My 4k ultra blu-ray player has 2 hdmi outputs, 1 for video and 1 for audio. To watch/listen in dolby truhd, i have video going to my tv and audio to the receiver. Unfortunately, my 4k xfinity box only has 1 hdmi out. I tried splitting the hdmi cables, but it seems there isn't enough signal strength to power both audio and video signals.
My question is, are there any future plans to upgrade/update the current generation of set top boxes? Or is there a solution that i don't know about for my special issue?
