I have a Roku Ultra. I bought it in late 2019 shortly after it was released and was the most current model at that time. In general it has worked well for me. However, I noticed that once in a while that the audio briefly drops out. It is not a constant drop. To the best of my memory, this appears to happen primarily with my Disney Plus and HBO Max apps. I suspect that it may have something to do with the apps, which may be an issue on the app developers' ends, it could be an internet connection related issue such as the companies proprietary or licensed server or computer systems that broadcast the streaming content, an internet connection issue anywhere between my house and where ever the content is being streamed from, or possibly my Wi-Fi (which generally performs well).
But based on your people's experience if it is a problem related to my Roku or home theater equipment, what settings or changes do I need to make?
If it helps, here is my home theater setup equipment:
TV: LG 55SM8600PUA
4K Disc Player: Sony UBP-X700
Sound System: Samsung HW-N650 Soundbar ( connected via HDMI to TV's assigned HDMI audio out port with wirelessly connected optional rear speakers)
Streaming Device: Roku Ultra [4670R (or whatever you labeled the Roku Ultra that was released in late 2019)]
