Thanks for posting in the Roku Community!
We would like to know how to identify and resolve any playback issues. For us to isolate your audio issue, it would be very helpful if you could answer the following questions:
- Does the issue only occur on a specific channel or across other channels installed on your device?
- Are you using an A/V receiver or soundbar with your TV/Roku player setup? If so, what is the make/model of that unit?
- In Settings > Audio > Audio mode, what setting do you have selected? Does the same issue occur if you change the setting to Stereo, etc.?
Moreover, if the issue only happens on one channel, removing the channel and then adding it back in may help.
You can visit this Support article for detailed instructions on how to do it: How to resolve a channel playback issue | Official Roku Support
Please keep us posted and we'll continue assisting you from there.
