I've had all sorts of PC's and OS's but the one common s/w design issue about which I get irritated is this.........If I want to switch from listening to my music via my headphones output to my speakers, I can only achieve that by unplugging the headphones. I have an iMAC with OS X Maverick v10.10.5 AND two Windows machines, (XP and WIN 7) and they all require that I fiddle around the back of the machines to switch the sound output destination. There must be a widget/gadget/ software runaround to allow fast switching of output devices. Can anyone tell me where and/or how? Thank you.
