@paulburr52: Your Yamaha RX-V677 receiver will get a sound source signal from the TCL TV under either (or both) of the following attachments:

HDMI: Connect HDMI cable from HDMI3 port on TCL TV to the HDMI OUT port on RX-V677 receiver. On the receiver side, HDMI Control and ARC must both be set to 'On' in order for ARC to work.  See pages 23 and 134 in the RX-V677 manual. On the TCL TV side, as previously stated, under Settings, System, Control other devices (CEC), Search for CEC devices, you should see your RX-V677 receiver identified with a HDMI3 identifier and an asterisk (*) signifying that it is an audio device. ARC must be enabled.  In the Control other devices (CEC) menu, ARC must be enabled, but System audio control, 1-touch play, and System standby do not have to be enabled in order for ARC to work (read the TCL manual for a description of those additional features).

Optical digital: Connect optical digital cable from optical digital OUT port on TCL TV to the AV4 digital optical IN port on Yamaha RX-V677 receiver.  With this method, manually switch the receiver to the AV4 input (or use the default 'TV' scene  button on the receiver front panel or the remote).

With either connection method (HDMI or optical digital) , the receiver will use the default 'TV' scene setting to produce sound from the TCL TV as input source, assuming that you have not reprogrammed the 'TV' scene setting button from its AV4 input default.

While the HDMI connection using ARC will allow some additional CEC functionality (like automatically turning the receiver on or off, automatic input switching, etc.), it does not work perfectly in all cases.  The optical digital connection essentially will produce the same sound from the TCL TV source (perhaps substituting Dolby Digital in place of Dolby Digital Plus or Dolby Atmos), but your ears won't hear the difference.

Both connection methods work from my TCL 55P605 to my Yamaha RX-V773 receiver.  With both connected but with CEC/ARC enabled on the TV and receiver menus, ARC trumps the optical digital connection.  Either way, the receiver shows the 'TV' as the receiver input source.

EDIT: Meant to say RX-V677 receiver, not RX-V667 (typo on my part).

It's great that you have an example of the connection working perfectly. I am running a Yamaha RXV677. High-speed HDMI cable, port4 in receiver port 3 in TCL R55615. All settings are correct and it still does not produce sound. The remote does control the TV as well as the receiver but no sound. Video example was inspiring but no help.

What port4 in the receiver??? Read the manual, dude! You should use HDMI OUT (ARC), see back panel of your receiver. ARC ARC ARC, repeat as mantra, you are using ARC to connect TV and your receiver.

True dat. I explicitly outlined the two connection methods in my previous post.  It 'appears' to be port 4 even when using the ARC HDMI OUT connection on his receiver, because that is the input source name ('TV') that the Yamaha receiver input switches to, whether using the HDMI ARC or the optical digital attachment method.  The same input name 'TV' is shown on the receiver front panel display when using the optical digital input connection on the receiver input labelled 'AV4' (port 4).  Either way (HDMI ARC or optical digital), the receiver switches to the input name 'TV' on its front panel display.

AWESOME!  Thanks, I'd been struggling with connecting via ARC to my Pioneer VSX-831 and your clear, concise explanation made it happen for me. As with others, I turned off Audio Auto Detect and DD+ and set Audio to DD and DTS for much better volume.

Okay, I’ve read and read and read this thread. I feel like I’m doing this correctly. I have an HDMI cable connected to both the ARC slots on the TV and Receiver. Along with that, both units have ARC turned on. My receiver is not found on the CEC check. I can control the Receiver volume using my Roku TV remote, but no sound.

TV: Sharp 4K UHD Roku Tv manufacturered Oct. 2017. (Don’t know the model number)
Receiver: Yamaha RX-V385

Really need the model number of your Sharp Roku TV for further investigation.  All I can think of without this, is that CEC is a prerequisite for ARC to work.  So if your receiver is not detected in a CEC scan, ARC may not really be enabled on both ends.

I have a Roku Sharp TV and a Yamaha soundbar with the same issue and figured it out.

First Stage:
1st Go into your "Settings" from your Roku's device Main Menu. 2nd Go into "System". 3rd Go to "Control Other Devices (CEC)". 4th Check "ARC (HDMI 1) and System Audio control". This is the advice that a few other people have been given however with a Yamaha sound bar there is one extra step that everybody's been missing.

Second Stage:
1st Go to "Settings" from Roku main menu. 2nd Go to "TV Inputs". 3rd Go to "HDMI 1 (ARC)" and add this to your Roku Channel menu.

Third Stage:
1st From your Roku Channel menu select "HDMI 1 (ARC)" 2nd From your "Yamaha Remote" hit "Setup". 3rd Go to "HDMI". 4th Go to "HDMI Audio Out". 5th Go to "TV". 6th Go to "HDMI Control". 7th Click "On". 8th Hit the "Home Botton" on your Roku remote.

This should solve the problem. I hope this helps.

I have a TCL55r617 that I want to pair with my Yamaha RX-V685. I have a HDMI cable connected to the HDMI arc port on the tv and to the hdmi out port on the receiver. I have read through the forum on this subject and I think I have done all of the steps that were listed. Still no sound through the receiver. Can someone list all of the steps in one reply so I can confirm I am doing them all. I disabled the tv speakers also.

I've connected Roku players and a couple if TVs (not Roku TVs) to several model Yamaha AVRs, and never had an issue. Looking at the menu on my Sharp Roku TV, HDMI 1 is labeled ARC, so make sure that's the jack the HDMI cable from the AVR uses. The only other potential menu option on the Roku TV is under Audio. Turn the TV speakers off, and S/PDIF and ARC should likely be on auto. On my Yamaha, I don't remember having to alter the TV audio input to ARC, but do ensure that ARC is enabled on the Yamaha menu. It looks like page 114 of the manual shows how to ensure it's set correctly. I'm pretty sure HDMI Control has to be enabled as well. 

I looked on the receiver hdmi connection and realized the cable was not in the arc port. Problem fixed. Thanks.

That would do it.  Glad you found the issue. 

I am also having a problem connecting my Yamaha RX-V365 to my TCL Roku TV (hopefully ok to post on this existing thread rather than creating a new post).

My problem seems to be even more basic --- getting the TV to even recognize the existence of the receiver.

Currently I have connected an HDMI cable (an Amazon basic HDMI cable: https://www.amazon.com/gp/product/B014I8T8FC) from the "out" HDMI on the Yamaha receiver to the HDMI 3 IN (ARC) port on the TCL Roku TV (apologies, I don't have the model number, but my wife bought it in 2015, the receipt says TCL 482222 1080P Roku LED HDTV 48FS3700, but in settings it says TCL Roku TV 5112X).

From searching online, I see that a "basic" step is to enable ARC on my Yamaha Receiver. However, I don't see any way to do this. I should note that the Yamaha receiver is not new and there seem to be different manuals online. The version of my yamaha receiver seems to correspond to the following manual:

https://usa.yamaha.com/files/download/o ... V365_U.pdf

rather than the current one:

https://usa.yamaha.com/files/download/o ... _En_A0.pdf

(the latter has instructions for turning on ARC, the former makes no mention of ARC).

Any help most appreciated.

Cheers,
F.

@Not_very_fast: If the first pdf manual is the one for your RX-V365 receiver, from the manual page 11 (page 15 in the pdf), that receiver predates sending audio through any of its HDMI inputs and output through the receiver's connected speakers.  So there is no ARC capability.  According to this manual, if you want to hear sound from your TV through the receiver's speakers, you need to connect an analog audio (red/white RCA cables) or a digital audio cable (optical or coaxial) from your TV to one of the corresponding inputs on your receiver.  Also, if you want to hear sound from a blu-ray player or cable box connected to the HDMI1 or HDMI2 inputs on the receiver through the receiver's speakers, you also need to make an analog audio or digital audio connection from the device to the receiver to hear the source's audio through the speakers connected to the receiver. 

Thanks for the update, I was suspecting as much.  I went and purchased a digital optical cable, which I have now connected from the SPDIF port on my Roku TV to the DTV/CBL optical digital input on my Yamaha receiver. However, I can't seem to get the ROKU TV to recognize anything. When I go to audio settings, it says "TV must be connected to receiver via S/PDIF or HDMI/ARC" but (even though is is connected via S/PDIF), "auto-detect" finds nothing.  I'm not sure that "search for CEC devices" is relevant if that only searches for HDMI, but that finds nothing either.
