Recently my sound driver has stopped working. I am pretty sure i caused it when i shut down my computer when it wasn't starting up properly. When I click on the sound icon in task manager (has a red x over it) it troubleshoots and says hardware changes might not have been detected. I've looked in device manager and when I open sound, video, etc the only thing in it is my webcam. I have tried reinstalling the realtek driver by downloading it off of the samsung website but that hasn't worked. If anyone has any ideas I am all ears.
