I feel your pain. Unfortunately it’s the only solution until Roku comes out with another update to undo the sound glitch the current one caused. But at least it works. It beats having to buy a whole new streaming device.
Sound started cutting off again today. Happened twice in 20 minutes first time I exited out and came back in and sound was back. Second time I went into that volume mode switch it on and the sound popped back on. Then I turned it back off again. it does have something to do with that volume mode. So maybe instead of people rebooting the whole system when the sound goes off they could just try that volume mode.
I was watching a program on Roku and the sound just cut out. I unplugged the power but it just kept on happening. I finally gave up on it and watched the program on my computer. This has happened a number of times. I can't find any settings on the Roku that will help me out.
I started noticing this a few days ago. When i checked the system update, i noticed it last updated July 8, around the same time the problem started occurring. Ive owned my roku ultra for 3 years, this is the first time I'm getting these sound issues.
