|It might surprise you but sound issues can be tricky to sort out, especially remotely, but here are some ideas for starters:|
Go to the Control Panel > Volume tab and make sure that the volume slider is well over towards High. Also check that the Mute box is not ticked.
Next do two searches, first for *mid and then *.wav files. These are very basic audio files so when you find some check to see if they play when you double click them.
Check also that all sliders are well up and not muted in the Volume Control icon at the bottom of the screen near the clock.
I have sometimes found that the drivers installation has somehow got messed up. The way forward is to find your audio device in Device Manager and Uninstall it, then reboot. It will then set up your sound drivers when Windows restarts. I'd better say that this is at your own risk but I've never had any difficulty with the sound drivers restoring afterwards.
A hardware fault cannot be precluded.
