If the sound from your computer or mobile device is hissing, crackling, or fading in and out when you use headphones, it could be your headphone jack. If you have tested your headphones with other devices to make sure that they are working properly, then the problem is most likely in the jack. However, there are some simple things that you can to try to solve the problem before seeking repair.
It's possible that the headphone jack is just dusty or dirty. You can try using compressed air to clean out the debris to see if this solves your issues. A damp toothpick can also be used to gently clean out the jack and remove lint. However, you should be very careful when inserting anything into the jack to avoid further damage.
Check the settings on your computer or device. You might just need to update a driver or adjust the volume. Sometimes a device will automatically mute the volume when headphones are plugged in or removed. You should also check the connection by removing the headphones and re-inserting them. They might just be improperly inserted. Finally, try restarting the device to see if it solves the problem.
