Popping sound in clips

This could be either a glitch or just a temporary incident, to refresh the system we Settings > Network Settings > Advanced Settings > Alternate Mac Address > Clear it and the console should restart. It would definitely help if you could restart the internet router while the console is restarting.

After going through the troubleshooting steps mentioned, I invite you to perform a quick power cycle by turning off the console and then unplugging all the cables. After 2 to 3 minutes, re-plug them back again, then restart your console.

Had the same thing since the April update, before that it worked perfectly fine. Clips don't always appear in the 'my clips section' after the notification says that it's been recorded, sometimes the notification doesn't even pop up at all now. Had one instance
where I had no sound on one clip as well....thought this update was supposed to improve DVR *sigh*

If there are problems with xbox live with too many people online it can sometimes cause problems with sending message, achievements unlocking or in your case problems with gamer clips. I had problems with gamer clips recently as well. Two of my clips
recorded and uploaded but they were in low video quality and didn't have any sound. Another time I made a clip but it wasn't showing up in my recent captures list. Then a day or two later a notification popped up saying my clip was uploaded to xbox live.

I hear a creak every now and again but I'm guessing it's just the plastic case as the Xbox gets warmer

Am I really the only one? It sound like if you would tap the xbox with your finger

Mine does not have that issue you described. It's eerily silent. I now however do notice the godawful noise my external harddrive makes. I didn't notice that with the Xbox One but with the One X it becomes really noticeable.
