Static noise in headphones during mouse movement varies with power configuration settings
I'm probably dealing with a different kind of coil whine. My setup sounds quite similar to this one, but it's not likely to ruin your build. Trying out components in another PC would help clarify the issue. As you mentioned, moving your mouse affects the audio through the headphones, so it's probably coil whine. To reduce it, keep your headphone/audio cable away from any other cables that might interfere with sound or power.
Start by identifying the source of the sound... is it just through headphones? Double-check by testing without them to see if the noise disappears...
Yes, that's correct. The problem lies with interference in the analog signal, which is why switching to a digital connection to the DAC is the best solution. You're asking why you'd use an analog input on a DAC anyway—its main role is transforming digital audio into analog form.
I'm sorry, I misunderstood the line on the device. That's really frustrating, especially since I thought it was something else.
The sound appears only when using headphones, as if it's coming from them. I notice coil whine on two of my case fans, but this issue has been present before I installed them—it produces that noise without being affected by mouse activity, which differs from the problem I'm experiencing now.
