I have no sound on my laptop. The sound icon has dissappeared from the taskbar. It appears when i first start the pc, but dissappears fairly quickly.
In device manager it shows High definition audio device (i thought this was called ATI something before hand, but appears to have changed?)
I've updated the drivers and according to this they are both working correctly.
In control panel i can only access the volume mixer, but it says no device is installed. I cannot click on "manage devices" or "change system sounds"
I also have no "windows audio" or similar in the services. I've tried stopping/starting anything that looks fairly audio associated.
I really have no idea what to do? I thought it may be a registry key that had been deleted when i was cleanign the pc of malware etc, as it dissappeared on a reboot, and hasn't come back. the same happened with my webcam not long after i first got the laptop. I don't believe the hardware is damamged, but i don't really know what else it could be, so any ideas are welcome!
