Win XP Sound problem
Our son's PC was recently infected by a Crypto virus. There was nothing special on the machine so we reinstalled Win XP and all is now well, except there is no speaker sound. He has a simple amp and two speakers which connect to the sound jack on the rear of the PC. All attempts to make it work have failed and when I access the sound feature via control panel it says that there is no sound system. USB headphones work OK. Any ideas please? Many thanks.
