Hey guys, my HP Elite 8200 pc's headphones outputs both front and back was working fine but recently I started working with some different softwares at the same tine and had to keep switching between the Sound options in Sound Properties then all of a sudden I can't get any sound from either headphone outputs. Right now I am using a USB adapter to get sound but I would like to get back the use of the headphone outputs so anything I can try please?
