Hi. I just got my brand new Dell P2715Q 4K monitor for when Apple ship the new MacBook Pro. Until now I have connected my MacBook Air to the monitor and it works perfect (at 2K res), but I have a little issue with my sound, I have connected my Logitech speakers directly to the monitor and this prevents me from controlling the audio from my Apple Wireless Keyboard via F10, F11, F12. Is there some kind of workaround? I got the same problem with the brightness controls but those I have fixed with some software. I cloud always just connect the speakers to my MacBook Air but it would be easier to just let it stay in the monitor. Also when I got the speakers connected to my MacBook Air and I wake it up from screensaver the audio controls won't work before I remove the cable to the speakers and back in. Can anyone help me?
