I've got an LG OLED65B6P TV, a Sonos Playbar, and an AppleTV. I like to use the TV's native interface for Netflix etc, because it supports 4k. When doing that, I can't use the LG remote to control volume on the Playbar, because as far as I know the LG remote doesn't support infrared.

What can I do to fix this? IR blaster that hooks up to the TV via USB or RS232? The TV doesn't have IR or RF out (RF in only).

Right now I use the AppleTV remote for volume and the LG remote to play, pause, etc. It's mildly annoying and I have to explain it to guests...

My strong preference would be to simply control the Sonos volume with the LG remote, so I can use the pointer, etc.

If that won't work I'll have to decide between my current setup and a Harmony remote that won't control the pointer, I guess.
