The magic remotes work on Linux without an lg tv but require an lg tv if you’re not hooking them to Linux. That means you won’t have the gyroscopic cursor control if the remote is communicating directly with the non lg tv but if it’s communicating directly with your Linux computer then you will have gyroscopic cursor control.

If you don’t understand that distinction or how to handle it I recommend you don’t bet on having that feature.

You can’t remove or destroy the mic without taking the remote apart. Often remotes use many mics because it’s cheaper to use four shitty ones and run them into unused dsp channels than to use one good one, so you don’t even know if you got em all. The other benefit of many mics is that they work even when one is not in the optimal position to receive inputs like left handed holding or in a bin of other remotes.

Even if you did take the remote apart there’s no guarantee you would correctly recognize the microphones. On this very site is a highly upvoted post of a person triumphantly holding a resistor network and proclaiming they removed the mic from their remote. Next to the populated component labeled “m3”. M for microphone. 3 for the third one…

That person isn’t stupid and I’m not making fun of them. That resistor network may have been connected to the mic and removing it may have achieved what they wanted. My point is that it’s hard to read and interpret a pcb and it’s silkscreen especially when you don’t have specialized experience.

What you may have overlooked is the appletv4k. It’s really cheap and very functional. It is generally considered the most privacy respecting off the shelf streaming device. It doesn’t require any fucking around.

However you’d have to have your own jellyfin or plex server. Not that that’s hard, I got a sixteen year old pc in a closet that serves multiple streams very easily.
