I noticed yesterday that plugged into my case's front audio output port were no longer being detected, the system is still using my monitors built in stereos. At first my headphone jacks weren't fitting in snuggly, so I figured dust may be inside. I cleaned it out with an air compressor can and now the jacks fit fine but still no sound. I tested three different audio devices, all of which are confirmed to be functional. Reinstalled audio drivers and updated them etc. Pulling my hair out, don't know what to do, please help. Thanks.
