Long Press Mute Function Disabled
I have multiple Roku devices. The main unit I use is a Roku 4670X ULTRA. For over a year now I have been using this device every night. I use the YouTube app and access one of the 10 to 12 hour selections of relaxing/healing music. Once watching the video I have been able to long press (3 seconds) the mute button to get the TV display to turn off (go black) while keeping the audio working. A few daya ago this stopped working. I have spent multiple sessions on the phone with Roku support (under Support reference #: 13120646) but have made no progress. The last promise to call me back was apparently not true, no one called, so i was lied to by support. I have identified the issue on my own. I can see that the ULTRA was updated to software version 15.0.4 build 5531 on 10/8/2025, which is when this feature stopped working. I also have a Roku Express and a Roku Premiere + that have not been used for a while so I hooked up the Roku Premiere + to the involved TV and paired up the remote that I first experienced the issue with. The long press feature works fine with that device. I checked and found the software version on that device is 14.6.4 build 9915. I also checked the Roku Express with an even older version of software and the feature is working properly. CLEARLY this indicates a bug in the 15.0.4 build 5531 software. PLEASE get the development team to correct what has been broken by that software update.
