I have a big audio issue with my Hdfury Vertex 2 and My Cambridge Audio 751r v2
My chain is:
Panasonic 65-HZ100 TV eARC HDMI 2 ---> Vertex2 TX0 output ---> Vertex2 Audio out ---> CAMBRIDGE AUDIO 751R V2 HDMI Input 2.
AUTOMIX is my EDID configuration --> AUDIO OUT.
Tre Cambridge don't recognize in the Audio input, in HDMI, from Xbox One, Ps4 or Panasonic Apps (Netflix, Amazon, ecc...)
For the Audio i use an Hdmi Copper Cable PANASONIC rp-che30.
It works one time and donato work, for a day, tre next time i switch on.
Do you have any issue playing any audio from source at Vertex2 input ?
If that works fine and only eARC is making issue, please send a config export when you are trying and add it as attachment to your reply.
I believe the issue is simply that you need a custom CDS that match the cambridge audio capabilities.
