The second device I ordered in September 2014 by an additional HDMI port to operate with a variety of other devices on the TV set. Unfortunately, this switch only image. It can be teased out of him no sound. After error source search and try the said equipment on debut, I quickly came to the conclusion that the second switch seems broken, so it was sent back.
I very much hope that I simply had bad luck and would probably order a third day, otherwise I get by on a higher-quality solution.
