My eARC soundbar is often an ARC soundbar.
I have Samsung Q930D and Sony TV.
Sometimes the soundbar would show as ARC, but most of the time it was eARC. Currently, it seems to be about 50/50. The cable is the original one and I’m using the eARC HDMI port.
Another issue that happens is that the TV sometimes does not detect the soundbar at all, even after going into the sound settings and selecting test sound (you know what I mean) The only thing that helps is turning off both the TV and the soundbar and unplugging them from the power outlet. (It would be enough to unplug Only TV probably)
