My earphones were working fine until yesterday but today they started playing sound on the right side only. If I pull the earphones out slightly instead of keeping them fully inserted, then audio starts playing on the left side only. Earphones work fine on other devices. I checked the balance level, etc in the settings and everything is normal. Does this mean there's something wrong with my pc's audio jack? If so, what can I do about it? Should I buy a usb audio adapter and start using that instead or is there anything else I can do? Thanks.
