I am having the Fetch TV Mighty NO SOUND problem. My set up is as below:
I just bought a Viewsonic PX727 which is 4K, HDCP 2.2. My AV amp is 7.1 Onkyo TX SR706 bought in early 2000. (HDMI 1.3, no HDCP2.2)
Tried different connection methods:
1) FetchTV > Onkyo > projector = No video, No sound
2) Fetch TV > Projector = Video with stereo sound via projector's built-in speaker
3) Fetch TV > Jaycar HDMI 2.0 Audio Extractor > Video via HDMI to Projector + Digital audio to Onkyo : The result is: Video always works, however, with 5.1 audio, sometimes it works, sometimes it doesn't. When the audio does not work, I unplug the power chord the HDMI Audio Extrator, then the audio works.
I am thinking of buying Mi box 3 or Mi Box S.
The connection will be Mi Box > HMDI to projector for 4k video > Optical 5.1 audio to AVR. Will it work?
