OK...I am new here, and I am hoping to get some good advice from some of you experts on my system setup. Posted below is my present equipment: Samsung UN65JS8500 4K television Samsung UBD-K8500 4K Blu-Ray Player Pioneer Elite VSX-45 Receiver Energy Take Classic Home Theater Speaker System (5.1) Asus Dual Band Wireless AC-1900 Gigabit Router Arris SURFboard Cable Modem SB6121 Roku 2 Streaming Media Player Logitech Harmony Elite Universal Remote Sennheiser RS 170 Wireless Headphone I originally had it set up by a professional installer. The system has never worked totally right and I could not get the Sennheiser wireless headphones connected. All HDMI cables were run through the AV receiver (TV cable was run into the Samsung One Connect Remote and then into the Pioneer receiver). Doing it this way there was no way I could get the wireless headphones to work (I called tech support several times). Next I removed all cables from the receiver and plugged them into the One Connect box. Doing it this way, I could finally get the Sennheiser wireless headphones to work (I upgraded to the Sennheiser RS 175 with an optical plug in and ran the connection directly into the One Connect Box), but now I could not get the receiver to work with the system. The sound came from the TV instead of through Take Classic speakers. So...not sure what to do next. Any suggestions on how to get the whole system to work? I know this is asking alot. The original professionals will not come back unless I purchase more equipment from them (won't be buying from them again), and I have emailed a couple of other professional installers in my area, but they have not responded. My son-in-law is an electrical engineer, but he lives in Boston and I am in Michigan. So I am appealing to you for suggestions. Thanks ahead of time for any advice you can give.
