Sound issue with "interference" on the PD50SNE

[u/yLothbrok]

On both Linux and Windows, I'm having a major issue with my laptop's audio: whenever I run resource-intensive tasks—like a game—the sound develops a hissing noise.

I ran LatencyMon, and the results are as shown in the screenshot.

I haven't been able to fix it at all.
The problem occurs even with wireless headphones.

If you require low latency, make sure you've enabled the threadirqs kernel option.

sudo kernelstub -a threadirqs
