I forgot to mention that I’m disabled and scraping by on a very small Social Security disability pension, so price is a big factor. I already have a hand-me-down powered KVM switch, albeit, and old one that has no USB or Audio ports. It works fine for me though, since my old mouse and keyboard have PS/2 connectors.
My first searches for a speaker switch didn’t get any hits, but since reading your replies, I added “share” and “audio” to my search string a got lots of hits. For example:
[MODEL MK-7 COMPUTER AUDIO SPEAKER SWITCH BOX](http://electronicsusa.com/mk7.html)
For me, $25 + shipping is a lot to pay, but since I got the speakers free as hand-me-downs, I might be able to talk myself into “splurging” on this toy.
Thanks again for the suggestions!
