Same here! No matter what app or channel I’m watching the “no sound” thing happens. Sometimes it comes back on its own, other times I have to restart Roku...happening for over a week now several times a day. Grrrrrrrrr....
I have had the premium plan on Netflix since I purchased the TV and only started experiencing the stuttering audio a few weeks ago. The video has always been fine. Last night I removed the Netflix app and then reinstalled it. I watched a few hours of a show and didn’t have any audio dropouts so maybe that fixed it.
That’s actually what I did a few days ago, too, and then I binged the entire rest of Dead to Me season 2 and didn’t have a single issue. So hopefully that fixed it!
Thank you for contacting Roku.
I understand that you are facing issues with Netflix while watching 4K content.
This could be caused by a temporary issue that the channel provider is experiencing and maybe resolved if you reinstalled the channel.
Please follow the troubleshooting steps in the same sequence as mentioned below and see if the issue can be resolved.
Remove channel (highlight the channel, push the 'star' button on the Roku remote and select the option remove channel)
System update (home>settings>system>system update)
System restart (home>settings>system>system update)
Reinstall the channel.
If the issue persists and it happens only with Netflix,please contact the channel partner.

Thank you for choosing Roku, have a great day!
I found this thread from a Google search; I'm having the exact same problem, but with an Nvidia Shield. Only Netflix is affected, so it looks like a Netflix problem rather than a Roku problem. It's been happening to me a lot while watching The Good Place, and I don't remember it happening with anything else I've watched recently.
