Exertis | Technology Distribution I updated to 1.1.6.0 firmware on 2/3/23. My Sony Bravia XBR55X930E is connected to it over HDMI ARC and the TV is connected to a Roku Ultra via HDMI. I use the Roku Pro remote to manage volume and muting. Before the firmware update muting via the Roku remote was never an issue. Post firmware update occasionally after muting I cannot unmute unless I use the Vizio remote MUTE button to unmute. The TV stays on External Speakers so I am mystified why this is happening. I called Vizio but they passed the buck to Roku. Any ideas to troubleshoot, maybe a setting change?
