I have a Sony Vaio notebook, model VGN-FS920. I have sound when it first boots up, but then no sound after that. Can someone please help me fix it, before I spend money for something I could of fixed for free.
Can you confirm that the sounds you hear are coming from the speakers and not from the motherboard? The beeping sound that comes when the laptop is switched on is not related with your speakers. So, basically you may really need driver update. Check the link below for some useful downloads.
