I’m curious, how many people are aware of these sounds. I have designed, etched, and built my own switching power supplies along with winding my own transformers. I am aware of the source of the noise. So, does anyone else hear these high frequency sounds regularly?

      I thought it was maybe some kind of audio chip interference coming from the CPU as it’s not tied to cursor movement in my case

      Graphics system usually. Back in the day I used to be able to tell where on the screen the cursor was from the pitch of the coil whine.

      I buy better hardware nowadays 😂
