I got up too fast with the wire trapped on my arm and it yanked out of the 3.5mm port pretty forcefully. Plugging in my headphones has no sound but if I plug my headphones into my mixamp and then plug the mixamp aux cable in my PCs 3.5mm jack there's loud erm.. 'static' and 'popping/crackling' like connecting an electric guitar to an amp. Have I likely to just bust the port? Are they replaceable? Getting a 3.5mm jack for the front of my case sounds impossible without begging the manufacturer. Can I use a usb>3.5mm and the sound quality remain the same? Thanks in advance for your help
