How connect Bose speaker remote with Apple tv

Please specify your model Bose speaker. Is it a bluetooth speaker?

Connecting the speaker and operating a remote for it, are two separate things.

• Pairing bluetooth devices can be done in Settings﹥Remotes and Devices﹥Bluetooth﹥
• AirPlay speakers should be added to the Home app. Then they will be available as destination output in Control Center﹥Audio Controls.
• Changing the volume of bluetooth speakers can be done with the Siri Remote, and also in Control Center﹥Audio Controls.

Do you really think asking the same question 3 times within 5 minutes going to yield a faster response?
