Pretty much what the title says. I have a receiver with a limited number of HDMI ports and I need to try to combine a Wii-U & a PS4 into one port. I have read several reviews on HDMI switches and it seems like somebody is always complaining about audio or video cutting out on one system or the other. Anybody have experience with a switch that does the job effectively? I will be running surround sound along with my video.
