Can anyone confirm CEC for non-Alpha builds?

That's what HDMI-CEC is for. They just didn't build the command set in.

Fill out a detailed report, giving make and model of headset you use and send it to the development team.

I am in Alpha Skip ahead and sometimes get these issues. You could try backing out of the Insider program, to a public build and seeing if things work.

Remember Alpha and Alpha Skip Ahead are the cutting edge OS builds and can be full of bugs.

And this is just the alpha build.

Thank you for posting on the Xbox Forum.

I believe there is an issue with capturing content if you are using an Insider Build (Alpha, Alpha Skip-Ahead, Beta, Delta, and Omega).

Unfortunately there isn't a way to recover the full clip at this time, as far as I understand.

Hopefully this issue will be addressed in a coming update.

• Some users have reported that their clips are not recording the full length requested. This is being reported for 4K clips and non-4K clips. We are aware and investigating.

I hope this helps!
