The unit is spanking new. I have the latest driver installed. My OS is Windows 10x64 Version 10.0.17763. The interface makes random pops. They always come in pairs, with one moderate pop followed by a louder one, half a second apart or so. There is no apparent reason for this. It can happen anytime, e.g. while I'm watching a video, not interacting with the computer in any other way. It also happens at totally random intervals, but I'd say twice per hour at least.
The settings are so:
- Sample rate: 192'000kHz
- Output: 4 ch., 16bit
- Buffer: 2048 samples, safe mode off
