XG1 causing ARC / HDMI CEC issues

Hey there sports fans!

Just installed a new XG1 4K box, and it's causing HDMI CEC issues with my TV and sound bar.

I've got it connected to a Sony X85K TV, which is then connected via ARC to a Sony soundbar.

For a day or so it was working fine, but through various power-ons and offs, I stopped getting sound to the sound bar.

The TV can see the sound bar connected, as I can adjust its settings in the Home theater control options, but I get no audio.


So after messing with this until the wee hours of the morning, I noticed that the Bravia sync / CEC menu had no devices listed. I then pulled the HDMI cable from the XG1, put it back in, and then Bravia sync started working, and both the box and soundbar were visible and I was getting audio from the soundbar.

This, however, seems temporary, as when I shut off everything for 30 minutes, powered it back on I was back to the same no-audio state from the sound bar.

I’ve tried multiple cables as well, disconnected everything, cut the power for a few minutes, and nothing seems to make a permanent difference.  my previous xifinity box had no issues with the same setup.

Anyone got any ideas???

Greetings, @RolloTomasi! I hope your week has been treating you well. Thanks so much for taking a moment out of your busy day to leave a post on our community forum. I'm sorry to hear you're having issues with your cable box, but you have definitely come to the right place for assistance.

 

I actually had a similar issue with my own setup last year. Every once in a while, for no apparent reason, the signal from my HDMI cable stopped working. I was usually able to correct things by unplugging and reconnecting the HDMI cable, but sometimes I needed to reboot my DVR to get the signal back. Eventually, I was able to determine the issue was being caused by my system going in to power save mode. For some reason, it caused a conflict error in my DVR, cutting off the signal. Once I disabled the power save feature, it stopped happening, but that was after weeks and weeks of troubleshooting, replacing cables, replacing equipment, etc.

 

We can definitely go through some troubleshooting steps with you, to see if there is a hardware issue with your new DVR, but it may help to check the settings on your other devices as well, especially if you see this happening more frequently after periods of inactivity. Either way, we are here for your support. If you'd like to look into these issues, or if you have any questions about your options, please let me know.

I had ongoing issues of my XG1v4 becoming unresponsive after switching my Denon receiver to a different input and back again to the Xfinity input.  Turns out the DVR was misreading a CEC command that the AVR sent when switching to a different source.   Problem solved when I turned off CEC on the XG1v4, which is buried under the Power Preferences setting.  

Not saying that's the exact same issue you are having, but there's really no reason to leave CEC on with the Xfinity box and turning it off may fix you up.  Good luck.

Thanks for your reply. I've just disabled the CEC from the XG1, so will see what happens. Also, to help narrow stuff down I've got both a new XG1 box and sony sound bar coming today. 

Another thing I've noticed is that if the soundbar is powered on before the cable box, the problem doesn't seem to happen...at least not as much.

It's such a big mess, but hopefully all the new hardware will fix it.
