This one might be more of a GNOME3 question. I'm running the RHEL7 beta on a laptop where I used to run windows xp. It's a Dell Latitude w/docking station and the dock has a coax/digital sound output. On windows, it would automatically switch to the analog headphone jack if I plugged headphones in. With linux there is a widget in the top bar on GNOME that has the volume control and a 'sound settings' option that I can open and pick digital or headphone output but it has to be done manually. Is there any way to get the windows behavior of using headphone output whenever they are plugged in?
