I’m beginning to get deafening sudden white noise bursts. They are just happening on one seemingly random channel, even if it has no plugins or any processing enabled on the channel, and even if I create a new track and copy the audio to it it still happens.
What interface are you using? I had a Line 6 DI, usb connection, a few years back that would do the same thing. One of the updates screwed something up, and the computer would disconnect from the driver. The squeal was loud enough that it blew the tweeter in my left monitor. Line 6 updated the driver, and it went away. I quickly switched to a different interface.
I also had this happen to a friend when he hooked his usb interface up to a hub instead of the computer, and it did the same thing. Moved it to the computer, and it went away.
