1. I would try removing the batteries from the remote. Make sure it's not your remote sending the mute signal. I've read that Roku remotes can do strange things like that when the batteries are almost dead. Just remove them to see if it still happens.
2. I would try home>settings>system>power>restart. That seems to fix some problems.
3. There is something else called "clear the cache" which may not actually do what it says it does, but people have been reporting this fixes some problems:
Clear the cache (fixes random reboots)
Hit HOME 5 times.
UP once.
REWIND twice.
FAST FORWARD twice. (Clears cache & tv reboots itself. Be patient. It takes 1-2 minutes for the tv to go black, and come back on)
Wouldn't hurt to try that.
4. Also, home>settings>system>advanced>factory-reset might be interesting to do in your case. You can tell it you don't have internet (you'll set it up later). This loads a smaller, seemingly older UI, The antenna/cable tv interface is very different (like it used to be before 9.4).
I don't have cable, but I believe you could watch cable that way (without connecting the tv to internet during the setup. Just a "dumb" tv). See if the remote problem continues. If not, you can go into home>settings>network to create your network. At some point the tv will update to the latest software (if not immediately). If the problem returns, then you'd know it's the software (which causes a lot of problems. But, I'm skeptical it's causing yours.).
If, even after a factory reset without internet connection still causes the same problem, I think you could safely assume it's the hardware.
There is an IR sensor in the tv. You can replace those. There's videos online. Or, disconnect it and see if it stops (use the menu/channel-changing buttons on the bottom or back of the tv to watch a show, and see if the mute problem continues). If so, you could replace the sensor or use a Roku enhanced voice remote which doesn't use IR (it uses bluetooth or wifi). You'd have to make sure your tv is compatible with that remote. I'm not sure all Roku TVs are.
If the tv is still under warranty, obviously that's the way to go.
