Okay, so I'm a bit behind the times: I've used the same Panasonic Home Theater in a Box system for like 7 years, and have things connected via Optical Audio. But I purchased an Nvidia Shield on Prime Day, and it doesn't have an optical port, so I guess I have to come up with a new connection scheme. I'll list my components and connections and hopefully someone can help me connect things better/more efficiently. Components: TV: LG 50LA6200 50" 3D TV with 2tb portable hard drive full of media connected via USB Home Theater System: Panasonic SC-BTT270 3D, Blu Ray/DVD with wired 5.1 speaker setup Streaming Box: Amazon Fire TV (1st gen), loaded with Kodi, Plex, Netflix, etc. Game System: PS4 Cable Box: AT&T Uverse (Cisco ISB7500) Rarely even used. Network devices: Just installed: Extollo Lansocket 1500 powerline networking kit and unmanaged 5-port switch Network connections: I have connectivity through the powerline networking kit going to the Fire TV and the PS4. Everything else is wireless for the moment. Other connections: AUDIO: all devices are connected via optical audio, through an optical audio switcher. I don't know anything about ARC via HDMI. I think this may be the solution I'm looking for, but I don't know how to implement it. VIDEO: all devices are connected via HDMI, and I have an HDMI switcher that allows me to switch between the Fire TV (my primary "home base" when I sit down to watch something) and the PS4. I bought this Nvidia Shield w/controller, but there's no optical port, so it kind of doesn't work with my current setup. So my question is: what is a better/more efficient way to connect things? If the Shield works out, it will replace the Fire TV as my "home base." Thanks in advance! Notes: I will likely be upgrading TV and home theater systems before long, but until then, I'd like to use the components I have, so no "ditch that Panasonic and get a real home theater setup!" suggestions, please. Also, any Nvidia Shield tips for once I get it connected are also welcome!
