I have the same issue. Roku Express 4k+. Have it connected via HDMI direct to tv. I've tried removing and adding the app. Changing cables. Nothing helps. Always drops sound several times during movies.
Can you please provide us with more specific information about the issue you are experiencing? What is the affected channel? If the issue only happens in a specific movie, would you mind providing us with the title of the movie?
Did you restart your Roku before re-installing the channel? That step is crucial when performing the troubleshooting. If you haven't tried the suggested order (remove > restart > re-install).
HI I'm also getting sound loss in the middle of movies over multiple Roku Ultra devices. All but the Ultra in my living room are directly connected to my LG TV's via HDMI connection. All cables are 4k certified, and purchased at my local Resi. distributor as my company designs and installs both commercial and residential AV systems to include home theater.
The issue is that at a random point in any movie being presented via the Vudu app on the Ultra the sound will just stop while the movie will continue.
We would be more than happy to investigate this issue further.
Can you please provide us the following information:
-Roku device model, serial number, device ID, and software OS/version (these can all be found in Settings > System > About)
-does this issue occur on a specific channel? if so, what channel and what version/build is the channel (this can be found be selecting the channel on the Home screen and pressing the * button)
-tracker ID when this issue occurs (when you see this issue occur, press the Home button 5 times, followed by the Back button 5 times)
-steps to reproduce the issue you are seeing
Once we have this information, we will be able to pass it along to the appropriate Roku team to look into further.
