How to adjust volume on a Multi-Output Device?

I have several Multi-Output Devices set up where one output is the Macbook Air Speakers and the other output is another device. When I set the sound output to a Multi-Output Device, the volume control no longer works. I cannot use the keys on the keyboard or the slider in the menu bar. I must use Audio MIDI Setup to adjust the volume.

Is it possible to set the volume keys to adjust the Macbook Speakers while the output is set to a Multi-Output Device?

that is expected behaviour.

sorry, no. you cannot control the volume in multi-out mode. you must set the volume to a comfortable level before choosing multi-out.
