If you want to watch/listen to something you want your speakers/headphones, but if someone calls you would have to go to settings to switch to the Headset. But doing this kills the sound from the speakers. To get Volume from the Headset, you need to select the headset from PREF>Sound>OUTPUT and INPUT and select Headset name. Getting Audio out from more than 1 Device is not working properly. My work has changed over to VOIP phones now.
