Sometimes I use a headset with my iMac, but I often need to switch between both. Unfortunately, I need to unplug the headset every time to do this. This is a hassle, because the iMac is located far back at the table and is surrounded by documents and other things.
Back when I had Windows, I could just switch between "Internal Speakers", "Headset" and every other sound-system that was connected to the PC.
When using the options in the sound icon in the menu bar, the "Internal Speakers" option disappears as soon as the Headsets are plugged in.
How can I make them stay? I really would like to choose between both outputs without unplugging the headset.
edit: no workaround like in "Use internal speakers with others plugged in", just making "Internal Speakers" a permanent option without alternative solution
