i go to my device manager and the problem is with Vinyl AC'97 Codec combo Driver (WDM) information available on this in properties is
This device cannot start. (Code 10)
Click Troubleshoot to start the troubleshooter for this device.
I go to trouble shoot and any pointers on there are useless i have unistalled it , re-instaled it tried everything ...... the thing is i dropped my laptop on the floor from about 2 feet high the screen went blank i managed to get the laptop to re-start and wen i put it back on and tried to listen to some mp'3s this is when the problem has arisen ... every other aspect apart from the sound driver is working fine i dnt know if dropping had anything to do with this but i would imagine its a bit of a coincidence
