antneed Posted June 9, 2021 Share Posted June 9, 2021 Quick question, I want to use my Roku Ultra remote to control the volume of my AVR through HDMI CEC... Currently I have a Control4 SR 260 remote which controls everything perfectly. When I use my Roku I find the smaller remote more comfortable and better for my kids to use. For me to activate the HDMI CEC I have to activate it on my Sony TV (Bravia sync), my question and concern, I wasn’t sure if I activate HDMI CEC will it interfere or mess up any settings with my Control4 remote etc? Thank you. Quote Link to comment Share on other sites More sharing options...

msgreenf Posted June 9, 2021 Share Posted June 9, 2021 CEC is a control plain and you can;'t have too many control planes at once... Quote Link to comment Share on other sites More sharing options...
Cyknight Posted June 9, 2021 Share Posted June 9, 2021 uhhh. answered a little too fast maybe? HDMI CEC will turn things on and off and switch inputs etc independent from Control4, with likely no way for the system to (accurately) know the state anymore. Add to that in case of distributed systems with video switches outputs and inputs may or may not get turned off, and CEC can sometimes even wildly travel across video switches causing some very weird issues (think, turn off TV in living room, master tv turns off as well while the basement theatre receiver turns on.....). C4 itself doesn't support CEC control from it's controller (not even sure it's possible?) - so in most cases (basically excepting cases where video switches have built-in CEC control that C4 can utilize via the driver) it's best to shut it off to prevent multiple layers (or planes, maybe plains..to prevent pains? ) of control. It's not that C4 'doesn't play nice' with CEC as such, it's that you're creating conflict in who controls what. Quote Link to comment Share on other sites More sharing options...

johnnyboy Posted November 17, 2021 Share Posted November 17, 2021 I see that my dealer (the old one who went out of business) has my setup as follows: 1. ARC HDMI from TV to ARC HDMI on Integra AVR 2. CEC and ARC both "on" or "yes" in the AVR setup. Could I just add ther optical cable and turn off the CEC and ARC "on" and "yes" answers? I have some weird control issues every now and then and wonder from this thread if I would have more reliable system doing that. Do I need my current dealer to do this? I am capable of physically adding the cable and assigning TV audio source to optical in the AVR settings. Quote Link to comment Share on other sites More sharing options...
Cyknight Posted November 18, 2021 Share Posted November 18, 2021 CEC being on is likely to create some of those issues yes - unfortunately, in most cases it NEEDS to be on to enable ARC (only recently has this been changing) so you can't disable one without the other. And yes, a solution would be to use an optical cable from the TV - provided you indeed assign the input to the same source as ARC is using now, no dealer involvement is likely needed. Just note that depending on the TV you may need to change it's output settings as well, and I would suggest turning CEC off on the TV as well, or the per-existing link may cause some weird issues (uncommon - but not impossible) Quote Link to comment Share on other sites More sharing options...

I have this situation in two rooms and will add optical, turn off CEC and ARC on both the AVRs and TVs and see what happens. I have begun photographing the physical connections and the OSD settings of the AVRs before making changes to make sure I can go backwards if I have to). Thanks again. One other question on cabling. I have two Sonos connects. The old dealer had one connectedo an AVR with RCA analog cables and the other connected to a different AVR with coax. Do you know which is right? I hear no difference in sound quality. (Both AVRs have the alternative connection unused.) Quote Link to comment Share on other sites More sharing options...
Cyknight Posted November 18, 2021 Share Posted November 18, 2021 There will be no mayor difference in sound, both work fine, likely just a matter of available cables or inputs. Quote Link to comment Share on other sites More sharing options...
