Alright, i upgraded my graphics card to a radion and when i got it back from the guy who upgraded it i got a new default audio device Digital audio (HDMI.) which is the only one appearing on default audio devices. It says its working properly and its enabled. Also the guy who upgraded it told me i have to plug the speakers in the back jacks which i have plugged it into every single one and still it says "no speakers or headphones are plugged in" and i have no HDMI port on my desktop. so, basically what im trying to do is get my original default audio device and for there to be sound. i am currently running windows 7 professional, and the guy that upgraded it is to "busy" to fix it. Also i don't want to be connected to a tv just a regular monitor.
