Annoying sound from the buffels
There are two possible reasons for this,
Please check using another set up, it might be due to that your current set up’s plug has became defective, it also happens when the carbon inside the cable gets defective.
Solution: get a new head phone/set up. First check with your friend’s one.
Sometimes the input port in laptops and PCs’ gets defective, possible reasons for this to happen are: if it falls on hard grounds or somehow water or other liquids went inside (accidentally) or due to overheat of hardware.
Solution: try changing the port, maybe you have to change the sound card itself.
Hope that helps.
