I appear to have lost my volume facility on my laptop. The volume buttons are not working, after looking at a couple of things I have a message which said I have no audio system loaded.
I ave just tried that going back the past three months. I keep getting a message saying taht the system cannot be restored, no changes have been made. The message appears after the laptop has restarted
Not a good sign , MAY be due to infection and MAY be the reason you are having sound problems. Before going any further I would suggest a thorough scan of your pc for virus/malware/spyware and make sure your PC is fully updated with Microsoft updates.
