I've had my Roku TV for a year and a half. These past two weeks I noticed if the volume is above 30 the sound starts cutting out, every other second. This is consistent across all platforms, and video playback is perfectly fine. We do not use any additional stereo or HDMI systems, this issue is through the TV speakers. I've messed with the audio settings as per some of the articles on here and I've done a restart, no changes.
Thanks for the post.
It's possible that what you are experiencing is related to a hardware issue. Have you tried contacting the TV manufacturer support yet to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support for their products running the Roku OS.
