Dvr recordings audio go in and out randomly. Box does not have a power button. Unplugged and reset through the app no change.

Hello @user_gh1b7e, and thanks for reaching out on our Xfinity Community forums, and for letting us know what you've already tried.

Since unplugging the box and restarting it through the app hasn't helped, let's narrow down whether the issue is with the recording itself or its playback.

When you replay an affected recording, does the audio cut out at the exact same spots each time, or does it happen randomly?

If possible, please also play the affected recording through the Xfinity Stream app or another X1 box and let us know if the same audio issue occurs there. X1 DVR recordings can be played across compatible devices.

Those details will help us determine the best troubleshooting direction from here.
