Power Control for TV & Receiver with Xbox Series S/X?

Hey crew! I just got an Xbox Series S, and lost the ability for the console to turn on/off my TV and Receiver when the console is turned on via the controller. This worked fine with my Xbox One X, but now doesn't work with my XS/S. Any ideas? I'm certain I have the right settings selected in the options.

Yeah Microsoft killed the HDMI pass through and with that killed the built in IR blaster that was used to send IR commands to other AV gear. You might be able to duplicate the Functionality by enabling HDMI-CEC or Control (different vendors call it different things) which can send commands like power on/off and volume control through HDMI.
