Just some new observations with my XBOX One...
Had to buy a new headset last week. Many people I was in-game with would complain about it 'crackling', like there was a loose wire. No physical damage evident. I'll eventually get around to trying to file a warranty claim on the original headset so I can have a spare.
Used Skype for the first time last night to get into a conference call with a bunch of friends. Played some BF4 while in and it seemed fine, but then after a while I switched to just having the TV on in the background while we played on online PC game together. Though the audio was fine, the controller would occasionally turn off, so I had to turn it back on a few times. Then, after ~2 hrs of being on the call, the Xbox just shut down, leaving the TV, STB and AVR all on. I had to physically push the "X" button on the console to get it to power on (which of course then powered off all the other devices). Not sure why it did that, as I had been wiggling the controller sticks every 5-10 minutes just to make sure it stayed 'awake'.
Overall, I'm still very pleased with my XBone, despite a few bugs here and there.
