: Since it's about a month later, you probably picked one already but here's my setup. I have the TCL 55" Roku 55P607 TV. It has Optical and HDMI (ARC), plus two normal HDMI inputs and other inputs/outputs.
I got a Yamaha YAS-107 which has multiple inputs, including optical, Bluetooth, 3mm stereo jack, HDMI in and HDMI out (ARC) ports. Got it from Amazon for $199. I just saw a Crutchfield ad a few days prior to Thanksgiving in the US where they have it for $179.
I LOVE IT! LOL.
The TCL TV has HDMI CEC so when both HDMI ARC jacks are connected with an HDMI 2.0 cable, the soundbar turns on and off with the TV but not the reverse. Turning off the soundbar doesn't turn off the TV. With CEC enabled, the TV Roku remote volume controls the soundbar volume showing the level on the screen. Using the soundbar remote also shows the sound level on the TV. Plugging the earbuds into the Roku remote cuts off the soundbar, as it should.
You can turn off the TCL's speakers, and get it set up for HDMI ARC and CEC control. Check the TCL and YAS-107 manuals for how to turn that the CEC/HDMI control function. They both have to have their control options turned on. Granted I'm using this setup in my bedroom but the sound is phenomenal. I think it has decent bass even without a subwoofer. You can increase or decrease the bass level plus it has a Bass Enhance feature for it's builtin subwoofers. I like being able to cut down the bass to a minimum at night, or pump it up during the day.
I just did the firmware update on mine to get DTS:X. I can attach a USB 3.0 flash drive to the TV with a video file that has DTS:X and the DD/DTS led turns red showing it's decoding DTS:X with the 3D Surround button pressed. Green means regular Dolby. No Dolby Atmos though. Plus it's Dolby Digital, not DD+.
I'm extremely happy with the combination of the TCL TV and the Yamaha soundbar.
Please let up know what you went with and how you like it.
