Recently I purchased an external display for my MacBook Pro (2017). I chose an LG 27UK850. The display has built-in speakers and is connected to my MacBook via USB-C port.
The speakers are working fine, but I can't use the volume keys (+/-) on my keyboard any more. If I want to change the volume I have to use the buttons under the display.
Is there any way or a "hack" to enable volume control from my keyboard?
