Hero4 4K issues with VW 600ES
I just returned from a Safari and stay at Giraffe Manor in Kenya. I got some amazing 4K video which I can play direct to the 600ES via HDMI but of course it does not have sound. So I have hooked it up with a powered HDMI splitter and it sends the 4K video to the 600ES but when I run the second HDMI to the AUX input on my Integra AV system, I still get no sound. However, when I run direct from the Hero4 to the AUX input on the Integra, I get what looks like an upscaled image but not 4K and still no sound. Yet if I hook the Hero4 up to a 1080P TV via HDMI I get 1080P with sound using the same HDMI cables that I used on the hookups to the 600ES. Now when I run 3D source through the AUX input on the Integra, I get good 3D and sound with no issues. I must say though that if I run 3D source through the splitter, and then through the Integra, I get good 3D image but the sound keeps cutting out, which acts like a HDMI handshake issue, which you can audibly hear the click as the sound goes in and out. Hence, why I have been running 3D source, my own videos, from the Fuji W3 to the Integra via the AUX input and that works fine. The weird thing is that running the Hero4 through the splitter gives me a great 4K picture but I can't seem figure a way to get sound with it.
Has any body run in to issues with sound output from a 4K source with any AV system matched with either the 600ES or the 1000ES? I have tried just about everything I can think of.
