One of the best things about the HDMI standard is the Consumer Electronics Control ( HDMI - CEC ) , which lets different equipment check each other . This can be as round-eyed as having a TV routine on with your Blu - light beam histrion and set itself to the right duct , or using HDMI Arc to send sound from the idiot box to a soundbar . As good as it sounds , if you have a problem with HDMI ARC and CEC not working , then you ’ve total to the right situation . Here ’s what you need to cognize .

First , it ’s deserving excuse that all HDMI - CEC is a monetary standard of sorts , manufacturers have implement it in slimly different way . The system is also very particular about which devices are connected first , and in which order they ’re connected in . If you ’re having trouble getting all of the features working , we ’ll show you what to do – let in catch CEC to work – so that your tv set will turn on and off automatically , and trouble-shoot HDMI ARC to make it work all of the clock time .

What we used

We tested these step on multiple TVs and soundbars , including the Sonos Arc .

The short version

Step 1.

Turn on HDMI-CEC

HDMI - CEC has to be enabled on all devices . What makes this harder is that devices all call this something slightly different . For example , Sky Q call the setting HDMI control , LG calls it Simplink , Samsung foretell it Anynet+ , Sony calls it Bravia Sync , and Panasonic call it VIERA Link or EZ - Sync . That make things a little more complicated , but you just require to take care in the setting menu for the HDMI option and you should find the right control . It ’s of import to enable HDMI - CEC for all equipment , including soundbars , TVs , situated - top loge and Blu - ray players . If you had HDMI - CEC disabled on any devices , then this could be your problem . However , if the mount was enable on everything ( or you activate the preferences ) and HDMI - CEC is n’t working , then you involve to jump to step 2 .

Step 2.

HDMI - CEC is really fussy about the order that devices are plugged in , as this impress the handshake that makes the system work . Where HDMI - CEC is n’t working properly , you necessitate to deform everything off at the plug and remove all HDMI cables from your TV.Next , turn your telecasting on first . Then , if you have any external audio equipment ( soundbar or AV amp ) , you demand to plug these into an HDMI port on your TV first , and then power them on . Next , punch in a arrange - top box , such as Sky Q , via HDMI and power it on . Finally , follow up with media player and Blu - beam players . This should make HDMI - CEC work the right way , so turning on Sky Q , for example , will turn on the TV and set it to the right channel . However , do n’t be surprised if turning off a set - top boxwood leaves the TV on , as this is often the case .

Step 3.

Fix HDMI ARC

The HDMI Audio Return Channel ( ARC ) is a subset of the HDMI - CEC criterion , and get the idiot box send sound over an HDMI cable to a soundbar or AV receiver . If you ’re not grow any sound this way , then you should , first of all , follow stride two above . Next , you demand to place your TV to use HDMI arc , which will mechanically send audio to your soundbar .

Step 4.

Check the audio formats you’re using

If you still do n’t get heavy , or sound is intermittent , then you could have a job with audio formats not being sustain . For example , you could set Sky Q to use Dolby Digital Plus , but if your soundbar and TV do n’t support this data formatting , you wo n’t get any sound recording . So , you need to check the sound output signal of each equipment and make certain that they ’re set to something compatible . Sky Q gives you normal ( stereo ) , Dolby Digital and Dolby Digital Plus , for example , which you could hear in turn . For Blu - ray of light player where you get no sound , try going into the preferences menu and selecting PCM as the output , which will trammel you to stereo sound on boob tube that have HDMI ARC , but you’re able to get full surround sound from television with HDMI eARC .

Step 5.

Reboot if you’re not getting the right sound

It ’s worth confirm whether you ’re getting the level-headed data format that you expect . Soundbars and adenosine monophosphate with a screen will usually tell you what formatting they ’re act , but there ’s often an on - screen door menu that you’re able to use . For Sonos system , you could use the app to see . We’d had problem with our circle - up not passing on the Dolby Atmos signal . Our way to fix this is to bring up the player we ’re using by need the top executive out , waiting 10 seconds and then reconnecting power . If that does n’t work , then bring up the boob tube by removing mogul , and wait 10 seconds usually does work .

FAQs

Optical is effective , although it is depressed bandwidth so does n’t stand the latest heavy data format such as Dolby Atmos .

It ’s all about the handshake , and sometimes devices get confused and ca n’t see what they ’re imagine to be communicating with , which postulate a reboot to force redetection .
