I'm having difficulty extracting stereo sound from my HDMI stream. HDMI comes from cable box as Dolby 5.1, goes to my receiver, and then to my TV. I need to have 2ch audio extracted from the HDMI stream, to connect to phono jacks on my whole-house audio system's input. If I set the cable box to output Dolby 5.1, all I get from the extractor is static. However, if I set the cable box to output 2ch, I get signal out of the whole-house audio speakers but no Dolby 5.1 to the receiver. Is there a way to configure the extractor so that it passes through 5.1 to the receiver while outputting 2ch to the house system? Based on the description of the item (preserves HDMI audio while outputting analog audio), it seems like this configuration should be possible. Thank you! (PRO-HDRextract)

Please try the following switches and let me know if it works. MODE 1: - Up/Dn/Up/Up. MODE 2: - Dn/Up/Up/Up. Note: Mode 1 - Pin 1 and 2: Video - Pin 2 and 4 : Audio Mode 2: for extractor only. Please power cycle our box after making changes, if the box is currently powered on.

I bought this splitter in order to stream 1080p video to youtube while playing my xbox one x games at 4k. I saw that this splitter was able to do this hence why I bought this splitter. I am currently having issues in regards to my Elgato game capture working. When I wire everything like the directions says, my xbox one x displays perfectly fine on my 4k monitor but does not display on my elgato game capture software. I tried to switch the EDID switches but that did not help. I tried redownloading the elgato software and this did not help either. I disconnected everything and routed everything to through the elgato device just to make sure the Elgato device itself was not malfunctioning and found that it was working perfectly fine so there is something wrong with the prophecy device I bought. Is there a way that this can be fixed so that I can stream 1080p video while simultaneously playing my games in 4k? Thank you and I hope to hear from you soon. (PRO-HDMI2DP)

This is a common setup and it should work. There are 3 areas you need to check. 1) Keep all DIP switches up (default position). Power cycle our Splitter everytime you make changes to these EDID switches. 2) On your Xbox One X, uncheck 4:2:2 under Display Settings. 3) If you've launched an HDCP protected app, such as Netflix or Amazon, your Xbox will be HDCP locked and your Elgato won't work. Do a hard shutdown/restart to clear HDCP. Putting your Xbox to sleep won't clear HDCP protection.
