I have a 2017 MacBook Pro that is hooked up to a Samsung TV via a USB-C Digital AV Multiport Adapter. When the default audio is set to the Samsung TV I cannot control the audio via the volume control keys on top of the keyboard. Only the Samsung TV remote adjusts the volume.

When the default audio is changed back to the laptop I'm able to control the volume using the volume keys on the keyboard.

Any suggestions on how I can control the volume on the TV using the keyboard keys is appreciated.
