So the other day my headphones began malfunctioning in that sound only came through one side. Initially I thought it was an issue with the headphones, but they work properly when plugged into other devices, and other headphones have the same problem when plugged into my laptop. I'm guessing the issue is a hardware one with the headphone jack (sound is working normally otherwise), but are there any solutions that can be done at home?
If you can open the system and replace the jack, then you can do that at home. If you are asking if you can do something without actually replacing a bad jack, not really. You can try using contact cleaner on the connection but that also would mean you need to open it and remove the jack so you don't spray stuff inside the laptop.
