I am not to clued up on computers so please understand if i dont make myself clear My son came to me and said his laptop had no sound,so I tried to find the problem. I found there was a yellow mark against the media audio controller in the device manager and no device showing in the sound and audio properties.So I read through some earlier threads about this problem,went to the toshiba site and downloaded the Soundmax digital audio driver and installed it. Went back to the device manager no yellow marks,went to sound and audio properties and it showed the default device as Soundmax digital audio,so I thought I had sorted the problem but alas, I have no sound from the speakers but have sound out of the headphones socket. Sorry about the long post but it was the only way I could expain it. It is a Toshiba Satellite Pro A10 model PSA15E-01PJY-EN os Windows XP Home Version 2002 Service Pk 3 motherboard Intel i852GM Thanks in advance for any help, Brian.
