I have the same problem with my TV.  TCL tv and TCL sound bar.

I was using a TCL sound bar with the ARC HDMI connection.  After unplugging the speaker and setting the sound to auto, the volume incremented by 1 either up or down.  When I plug the speaker back in using the same cable, it goes back to increments of 3 or 4.  I am going to try an optical connection to see if that works.

Thanks for the posts.

Please be aware that if you are using a third party audio product such as a soundbar, the reason you may be seeing this behavior is that the Roku TV may be trying to match the volume level/control of the soundbar.

For example, if the Roku TV volume control is from 1-100 and soundbar volume control is from 1-50, changing the volume control of the Roku TV would not correlate with a 1:1 change with soundbar volume.

We hope this provides clarification regarding the issue you are experiencing with your Roku TV.

Thanks,
Danny

Really appreciate your response to fix but it doesn't explain how you do this? Step by step or a link would be helpful

1. Press Home on your Roku TV remote
2. Scroll and select Settings
