BlueRigger HDMI CEC Less Adapter (4K UHD, ARC, Ethernet, Male to Female CEC Blocker) - Compatible with HDTV, TV Stick, Chromecast, Nintendo Switch, Xbox, PS5, PC, Soundbar

I recently got a new sound bar that requires enabling CEC to get Dolby Atmos. This all worked great, except that my Mac mini started fighting over input priority and would turn the TV on every five minutes. There is no way to disable CEC without disabling Dolby Atmos. So, I bought this little adapter hoping it would help. It did! Installation was simple and I still had 4k DV-HDR 120Hz and Dolby Atmos. The input is still properly recognized and all the issues I had are now gone.

I use an HDMI splitter to share a KScape player in two rooms. In one of the rooms, I use a Sonos Arc Ultra with an LG TV. Unfortunately, to use eARC, CEC must be turned on in the TV. CEC was then causing the TV in the room room and an Apple TV in the other room to be linked inappropriately. I spent a lot of time and money looking for a solution. Someone suggested this device on a Reddit forum and I immediately bought it. It worked perfectly to break the unwanted CEC connection. It is such a cheap solution compared to the eARC HDMI switches I was trying!

Resolved problem of switching automatically audio to external speakers when watching a DVD and the receiver is on.

We've had our audio guy for 35+ years, one of the best in the industry around our area. He installed all new equipment and advised us to get this particular adapter so that our TV box would turn off each time. He installed it and since that point, it requires us to once again login to our internet connection and then the whole system freezes. We unhook the adapter and everything is normal again. We will personally look each time to ensure the system is turned off when leaving town for a while. Ended up returning them.

Couldn't get the HDMI to communicate with my Bravia TV until I put this in line and everything works perfect

My setup is Apple TV >> Samsung >> Bose Soundbar and the Bose soundbar sending a signal to turn off the TV and AppleTV when not receiving an audio signal with 15 minutes or something like that. Put this in the back of the AppleTV and everything stays on as intended.

Worker as intended. It blocks a CEC. Ended up returning it since it did not resolve my Samsung Soundbar dropping arc. I ended up settling and turned bitstream off and going back to pcm. With this product just be mindful of your HDMI port location as its basically the size of the bulky end of your typical HDMI cable. You might not have enough room to run your HDMI cord or need something with a right angle.

Was having problems with the HDMI-CEC from other devices interfering with the sound bar connected to ARC/eARC. The TV was not recognizing the sound bar. Adding the BlueRigger adapter to the non-ARC HDMI inputs corrected the problem. Sound bar is now recognized by the TV and controlled by the TV remote.

Works as advertised. I have the SONOS system connected to HDMI eARC and a streaming box to normal HDMI. The streaming device is always stealing the eARC? So I had to unplug the device every time I turn off my TV. With this adapter, it works as expected, I no longer have to unplug anything.

Good quality. Able to upscale the picture with 3D. Not suitable for all devices. A good choice for anyone who has a reputed device.

This adapter is a life saver. My TV Box now no longer interferes with AV receiver’s audio from the TV over HDMI ARC. Earlier, I accidentally discovered that the Sony Bravia’s audio worked with Yamaha 7.2 AV receiver only with the TV Box disconnected. The TV box’s HDMI CEC feature was supposedly causing the ARC “handshake” between TV, AV receiver and TV Box to malfunction. There was no audio from AV receiver. While searching on google, I came across a blog that pointed to this CEC-less HDMI adapter. Realizing the root cause of the problem, I was certain this adapter would do the job. I ordered this a week ago and it arrived today in Dubai. I tested connections this evening and all works perfectly now. I am so happy. This adapter can connect to the TV-end or the TV box-end of the HDMI cable. It doesn’t matter. Make sure you first determine what device is causing the problem and then use this adapter to block CEC signal on that particular HDMI device and cable.

My Samsung Q870A/XY soundbar has worked with my Samsung TU8000 TV for a long time without issue. Have always used the eARC function so I can control soundbar, TV and NVIDIA Shield Pro using the Shield (or Samsung TV) controller. For some reason that eARC / CEC functionality suddenly stopped working and my Samsung TV no longer recognised by Samsung soundbar. Perhaps it was a firmware update on one of the two devices, HDMI handshake issues or a device introduced a CEC conflict? After much painful power cycling, HDMI cable testing, HDMI cable swapping, general diagnostics and forum trawling I worked out what the issue was. If only the soundbar was connected by HDMI to the TV eARC HDMI port then soundbar and TV worked. As soon as any other device was connected to HDMI 1 or HDMI 3 (the non eARC spare inputs on my TV) the soundbar would drop off and wouldn’t be ‘seen’ by the TV. That’s when I learned about my new nemesis: PIN 13 in HDMI causing issues with unwanted CEC signals. Yes, as described on some websites you could get some pliers and a magnifying glass out to prise out the offending pin on one of your cables, or you could carefully tape over pin 13 with electrical tape. Realistically though, why would you risk messing up thousands of dollars worth of equipment in lieu of testing a $14 delivered solution with free returns? Anyway, I bought 2 of these for the 2 non-eARC HDMI inputs on my TV and everything worked immediately. I now have my Switch and PS4 rigged up with the soundbar fully working on all sources with Atmos. Why Samsung and other AV companies don’t suggest testing CEC-less adapters as part of the troubleshooting process is beyond me. I don’t normally bother leaving reviews, but this problem was ‘doing my head in’ so I’m leaving as much detail as possible to help anyone else in a similar boat. I’d say if most of the above sounds familiar to you (even with different branded equipment) then this device could well be the solution you’re looking for. Good luck!

Does exactly as intended. Plugged a new mini pc into my Samsung TV and suddenly my Sonos Beam stopped working. After a bit of research found out it was probably a cec signal conflict when I introduced the new bit of kit. Bought this to block the new signal from the mini pc and worked a treat.
