View Full Version : Controlling dual display sound from keyboard

09-27-2014, 05:20 AM
I have an iMac & thunderbolt display and I have changed the settings so that sound comes from both. However, I cannot control the volume from the keyboard or the Mac itself (volume in menu bar) as it is greyed out?

Is there any way around this? Seems strange to be able to use dual display sound but not control the volume?
