Reddit mentions of KabelDirekt Optical Digital Audio Cable (3 Feet) Home Theater Fiber Optic Toslink Male to Male Gold Plated Optical Cables Best For Playstation & Xbox - Pro Series

Listen, the Yamaha 3 series is the absolute best value out there! For just $280 on sale, it’s ridiculous how much you get for your money as long as you don’t need more than 5.1! It has a great DAC (same used in the more expensive ones) and sound quality. Really crisp, clear, dynamic sound. Of course they skimp on Atmos/DTS:X but with a 5.1 setup Atmos won’t really make a big difference. Personally I think unless you can hook up 4 speakers to the ceiling you just won’t get a lot out of Atmos. Bouncing off the ceiling isn’t the same as actually being physically above you.

The other difference is the lack of banana plugs for the center and rear speakers although the current 385 now has them for all 5 speakers! So the 3XX is going to get even better from now on. This makes hooking up thicker gauge speaker wire a challenge but not impossible. I had a 367 in the past. Right now I have the RX-V483 paired with matched Polk Signatures. S35 center and S15s for both the front and surrounds. Like the Yamaha amp these are an amazing value. The center especially punches well above it weight.

Sometimes turning off HDMI Control and ARC on the receiver and turning off HDMI-CEC/Simplink on the LG and then turning them back on can fix issues. ARC is very finicky.

For example my 483 auto detected and labeled my Xbox One X and Spectrum DVR yet it didn’t do this for my OG PS4 nor Apple TV 4 (non-4K).

But again, if you can’t get ARC to deliver 5.1 without having to switch back and forth, order a quality Toslink cable like this and give it a shot. It should go from your TV to AV1 on the Yamaha. The sound quality for Netflix, YouTube, Amazon, Vudu and other apps will be nearly identical. I believe Toslink can handle up to 3 Mbit/s. It certainly handles regular full DTS 5.1 which is 1.5 Mbps which is much higher than DD+’s 640 kbps.

I’ve used this one in the past. Gold plated connectors and just top quality overall. Much better than the cheaper cables. Right now just $8:

You have 30 days to return it. I would try it out. If ARC stops acting up just send it back. Otherwise optical will always work 100% and this would just be for the internal streaming apps and built-in MKV player (photo & video).

If you haven’t tried yet, the LG players plays nearly everything you throw at it! I have dozens of 15-40 GB HEVC 4K Blu-ray HDR rips and they all playback flawlessly off of a cheap WD Passport 2 TB 5400 rpm drive. Unfortunately UHD rips don’t have Dolby Vision metadata but HDR10 with LG’s excellent dynamic tone mapping is good enough.

I noticed the same thing with mine. I even tried unplugging and reversing the ends of the cable and no matter what I did, it was always very loose in the Xbox.

It bothered me enough that I bought a new optical cable that snaps into the Xbox tightly. If you plan on buying a new one, just be aware that the quality varies greatly between manufacturers. I will give you a link to the one that I found on Amazon if you are interested. It's a very high quality cable. Just pick whatever length works for your setup.
