After doing some recent work on my PC (installing a custom water loop) when restarting it I have found that none of my audio jacks work, the rear audio jack that plugs straight into the mother board will show as working on windows but not out put any sound and my headphones jack at the front will produce sound but also a huge amount of static interference. I have test both on the monitor headphone jack which uses Nvidia High definition audio instead of Realtek and they work fine so I'm confident it's not the devices. I have tried reinstalling the drivers and have checked the HD audio cable is connected properly. At this point I can't think what else it could be?
