Hi, @cwbuckley
Thanks for posting, and welcome to the Roku Community.
We appreciate you for bringing this to our attention. At this moment, we'd like to ask for further details for our team to address the issue. What specific season and episode of the UFO Cowboys has no sound? Also, can you send us an image or a video referring to the issue?
We hope for your response so our team can address it promptly.
Best wishes,
