I bought a Kinivo 550BN HDMI switch this week to act as the input front-end to a Samsung HW-Q90R soundbar (only 2 input ports) which then feeds the TV via HDMI. I having a problem with it. I am using the 550BN with 3 HDMI input connections from a DirecTV HR54 receiver, Roku, and a Panasonic Blu-ray UHD player. The output from the 550BN feeds the Samsung soundbar via its HDMI1 input port. The output from the soundbar goes to a Samsung TV on its HDMI1 input port. Two components devices (Roku, DVD) works like it should with no problems except the DirecTV HR54. On an on/off cycle on the components, the audio from the HR54 is lost on the soundbar. The picture does get displayed on the TV. I also tried a HR44 and that has the same problem. If I hook the switch output directly to the TV (bypass the soundbar), it works fine. If I hook the HR54 directly to the soundbar (bypass the switch), it also works fine. It's crazy! I've searched around Google and do find others with somewhat the same issue with HR44 and other equipment, but never an answer of what is causing it. What's up with the DirecTV HDMI? Thanks.
