I restarted my computer today and suddenly there's a red cross on the speaker icon and when I hover over it says "No audio output device is installed". Also, when I run a dxdiag and go to the sound tab, it now says "No sound card was found. If one is expected, you should install a sound driver provided by the hardware manufacturer." despite the fact that everything was working fine until then. 
Please can anyone help me just get sound on my laptop
