Suddenly no sound from soundbar, HDMI ARC and CEC stopped working
I have given up hope Roku will even get this fixed. I've had no luck in getting my TV/Soundbar/Roku working with the Roku Ultra LT (4801RW) installed. It's been about 2.5 years waiting and hoping it would eventually work with the latest update, but no go. When I have the LT installed and updated to the latest Firmware I don't get any sound out of my soundbar (Yamaha) which is connected through an HDMI Arc port on the TV. Fortunately, when I install my older Roku Ultra (4670X), the TV/Soundbar/Roku all work. So I'll just keep that installed and use the Roku Ultra LT on another TV.
Sound glitches after some time - high/low and distorted
It seems to be an older thread and I can't reply. I am having the same problem as https://community.roku.com/t5/Discussions/Roku-Ultra-Volume-glitch-after-some-time-Volume-glitched-high-or-low-and-distorted/td-p/867899 I can see the user reports it was not solved. I have this problem on both of my Roku ultras on an LG TV with earc soundbar and a Samsung TV using the built in speakers and in various apps - Netflix, Hulu, peacock, max, etc. So it's not the TV, it's not the app, the Rokus are rebooted and fully updated. Unfortunately as this other poster wrote it is random - it might happen after a few minutes it might not happen at all it might happen after watching for a few hours. The only fix I've found is to hit back to stop whatever is playing and resume it. I had a thought last night while trying to Google this problem and not finding much other than the post above. Could it be a bug in the Roku sound leveling feature? I absolutely have that turned on both my TV's because I feel like everything is practically unwatchable without it. I will try watching with it off to see if it repeats but again unfortunately it is not intentionally repeatable. I was wondering if anyone else has thought about this or if Roku can consider reviewing the sound leveling function for problems? edit: fixed typo
