I have tried something that seems to be working for the last 2 days: When using an app like Netflix, I pressed the * button and set the Volume Mode to Off. So far no problems,.. for now. I’ll post again in a day to update.
What finally worked was to set Roku back to factory settings... then, unfortunately you have to start over. But I found I did not loose any of my selected shows within the programs. Hopefully Roku corrects the problem. Now I’m going to see if there are any updated I may have missed. Good luck!
I’ve been dealing with this too. It started a couple months ago, and I noticed the Roku stick itself is very hot despite having free airflow around the device. Not sure I want to invest in a replacement considering a family member had the same thing happen to their Roku device also.
