ooops... my instructions is for windows xp. here's for vista...
you need t goto device manager to check the sound driver is there and working OK. click on the start button, then control panel, then system and maintenance, then device manager. expand the sound, video and game controllers. check the sound driver is listed there. also check other devices if any other sound device is installed.
and lastly, if you insert an audio CD, does the sound works? i suspect the sound is working OK but not the volume. you should get the volume slider in the sound, video and game controllers.
i havent got a vaio with me but sometimes you can control the volume using certain keys on the keyboard, for example pressing a Fn key together with the up/down volume key which is shared with another key.
