TCL Alto 6 2.0 Sound Bar volume with HDMI (3, 6, 9, 12, 16 instead of 1, 2, 3, 4, 5)
Initially connected TCL Alto 6 2.0 Sound Bar volume with HDMI to a TCL 55R617 Television using an optical cable.
No problem, except the Roku remote would not control sound and it was desired not to need to use the Sound Bar remote to control volume.
So I switched from optical cable to HDMI cable to use ARC. The volume seems slightly lower than using the optical cable. But the bizarre thing that is happening is that now, when raising volume when using the remote or doing it manually at the sound bar, instead of the volume numerical display going up in single digits (0, 1, 2 3, 4, 5 etc.), the numerical volume displayed goes up like this:

I'm having the same problem with my new Alto 6+ 2.1 sounder and sub connected through the ARC. Wildly different sound levels now, for example, Youtube was always a little louder that everything else, but now it has to be turned down to 9 (previously 20-ish) and Amazon went from around 30 to 60+. I have to be super careful when changing streaming channels, especially going to Youtube, which will then blow out your eardrums.
Also, the sound setting between TV, Music and Movie continually resets to TV no matter how many times I change it or through which menu.
