I had a bluescreen while i was away from my pc came back to the "start windows normally" option but thought nothing of it. Once logged in i noticed that no audio was working. the sound option in device manager shows the green bar moving as if audio is being played but when i go to the volume mixer it shows a empty bar on the program that should be showing green bar like in the sound manger. the "speaker" on the volume mixer is also not showing anything even though the sound manager "speaker" shows audio playing. I reinstalled my chipset driver and my realtek audio driver and got no change.
