I believe I'm having this same issue! Ever since the latest update to my Roku Streaming Stick+, the volume on my Samsung TV (using only the TV's speakers) goes crazy in both directions using the Roku remote. I can press the up button once and the volume blasts 10-40 volumes up. I can press the volume down button one time and the volume sometimes drops to 0 or drops 4-5 volumes down. Just now, I tried turning the volume up, pressed the up button once and the TV volume just rose to 75!
This is a very new issue and only started happening after the last update. I've had this same Roku device, remote, and TV for over 2 years...no issues. I have indeed trying to re-pair the remote. The issue still persists.
I also have another identical Samsung TV, identical Roku Streaming Stick+, and Roku remote upstairs and the exact same issue is occurring there, too.
Software version: 11.5.0 Build 4235 - last update was 10/26/2022
We are having the same problem. Been going on since the 11.5.0 update. Happens on all 4 of our Roku 4k Sticks.
