Audio on the Predator Helios Neo 16 has a documented cause that owners on the Acer Community keep finding: the PredatorSense utility and the DTS audio software interfere with the Realtek audio driver. One owner reports crackling while watching video only when PredatorSense runs in the background, or when changing the keyboard light during playback, and ending PredatorSense from the taskbar stopped it. Another writes that DTS and PredatorSense broke the speakers, and fixed it by using Microsoft's Show or Hide Updates tool to block the DTS packages from reinstalling while leaving the Realtek driver intact. A third thread describes freezes with LatencyMon showing real-time audio errors that show as clicks and pops. The recommended order is: close PredatorSense and test;
The checks in more detail
do a clean reinstall of the Realtek audio driver by uninstalling the audio device in Device Manager with its driver and installing Acer's download for your model; turn off audio enhancements; and, if the DTS package keeps coming back, block it with the hide-updates tool. Check LatencyMon if clicks persist. Remember to restart after each change, since the audio service caches settings, and test with the same video each time so you can compare.
If you use headphones with a USB DAC, test those separately, because crackle in the speakers can differ from crackle in the headphones. If you stream or record, apps like OBS or Discord can take exclusive control of the audio device, which silences other apps, and the setting to allow exclusive mode is in the speaker properties under Advanced. Untick Allow applications to take exclusive control, restart the app, and test again.
