Did your pc have working sound when new?
Check the volume level, it's easy to turn it right down or mute it.
Check if the speakers are selected by going to the speaker icon in tray near the current time.
Right click on speaker icon, choose 'playback devices'.
A new box appears, with a speaker and it should have a green tick over it.
Right click on the icon and choose the option 'test', you should hear audio tones.
If you don't have a green tick, right click on icon and choose 'enable'.
