Ihave a Toshibs Sattelite Pro a10 laptop with Soundmax onboard audio. Following a rebuild I have installed XP (SP2) and all drivers from Toshiba's website. Despite all o.k. in Device Manager and loudspeaker icon on screen there is no sound. I've uninstalled and reinstalled, rebuilt with XP Home and XP Pro, but no joy from internal or external speakers. I'm reasonably competent with installations but this has me stumped! Any help much appreciated!
