Popping and crackling is a frequently posted problem. Unfortunately there is no "one fix" for the problem. Drivers
are one issue. Use the Samsung provided RealTek driver
, do not use one obtained from somewhere else or what Windows will install. Video drivers can be another issue. Although you have a laptop and probably connecting to the internet via wi-fi, the wi-fi device/connection can be another issue.
Running processes can be another cause. I had a DPC latency issue with a new desktop build that turned out to be a program that was monitoring the PC health. After I uninstalled that program the DPC latency spikes went away. So, check what is in the startup or what is in the Notification Area (lower right).
There have been many posts on here (and other forums) about this.
