Thanks for the posts and providing us with your information.
I have passed along your concerns and details to the appropriate Roku team to investigate further.
I'll send along two more. I look forward to hearing what the Roku team learns. Thank you!
Here is another example of no sound when trying to watch YouTube TV from my Samsung QN65Q70RAFXZA. Roku Ultra (4800 series)
I’m considering switching to a Fire-Stick from Amazon.
I'm still hoping Roku can come up with a fix. But I will consider another option if they can't correct the sound issues.
Same issue with new one I received Saturday. Software up to date. No sound bar. Just TV speakers on old Samsung TV. Had Roku stick+ hooked to it prior for years. This one I put on Ethernet. Had to hard reboot with power cord. Remote Restart did not fix anything. No sound on any app. Also seemed to be slow prior to power reboot. Do not have any other devices connected, used everything that came with Ultra 4802R. Have 2 other much older Rokus on TV's and never had this issue. Strange. Will keep an eye out on this. Tx. I see by posts a lot pf others having same issue.
Yes the only way I've found to fix the no sound issue is to unplug the Roku and wait for it to reboot. But not a great option when you have to do it multiple times per week or day. Roku Ultra (4800 series)
Any updates from the Roku team about the lack of sound with my Roku and Samsung TV? Is there any additional information they need?
Here is another example of no sound when turning on the Roku for YouTube TV on our Samsung UN40MU7000. Roku Ultra (4800 series) The issue does happen on other channels such as Prime Video, Netflix, HBO Max but I don't watch those as often. As usual, I fix by disconnecting the power from the Roku and then reconnect.
Any updates from the Roku team looking into this issue?
