Hello,
I have 3 controllers, and one of them has this hissing static noise coming through the left headphone via cable, and I don't know what to do. I tried to clean the audio jack port with a Q-Tip and isopropyl alcohol but didn't work.
Can someone please kindly help me fix this issue?
Best wishes.
Try using different headphones and a separate audio cable to rule out issues with either. Inspect the headphone jack for damage, and test the controller on a different device or with another controller to see if the static persists. If none of these solutions work, the controller may need professional repair.
