What does happen if you set the port to be eARC instead of plain ARC? Maybe it appears to be limited because it is set to ARC instead of eARC...
OK. I tried connecting my LG OLED CX to the A8 and playing a track (24bit / 96khz) via a usb stick connected to the TV. I too get only 48khz. Of course it could be the TV that downsamples the signal (or a limitation of the usb port on the TV) or it could just be that (like many others) Eversolo have chosen not to implement all the available ‘standards’ of e-ARC. It is not ONE standard but MANY. Even LG don’t use the full 48mbit but choose to go with only 40mbit for some TVs. It’s not pretty. But ‘standards’ are not always ‘standards’.
The ethernet port of my TV is only 10/100mbit (not the ‘normal’ 1000 gigabit). Companies are ‘crazy’ but it’s all about money, I guess. If you implement one standard, you have to make sure that every part of ‘the box’ can handle this. Handling more data means adding a faster CPU which makes ‘the box’ more expensive. Not that this is neccesarily relevant to the A8 since it will handle higher bit rates but maybe they need something more expensive behind the e-ARC port to handle higher bit rates? ‘Hardware’ related to HDMI before it’s sent to the DACs of the A8? Or ‘licensing’ is priced depending on implementation?
Use the TV's optical out connection instead of HDMI ARC. Do you get 96kHz on your A8 over its optical input?
Even optical out of TV into optical 1 of A8 only gives me 48khz. When I play the same track from my internal SSD it is 24bit/96khz. It might be the TV or maybe the A8 is showing the wrong data. Hard to be sure.
TV specs are not easy to come by but I’m pretty sure it can output more than 48khz PCM. This is all I could find for my model: (it doesn’t say anything about if it is input or output).
