How can I make my laptop's internal speakers work after installing Windows Vista?
I have a 15 "MacBook Pro recently I used training camp to install Windows Vista Home Edition 32-Bit. I had a little red light in my decision headphones and internal speakers laptop does not work. Headphones or external speakers connected work. Finally discovered that the red laser light is a system optics. I also found a way to turn it off after watching for a day and a half. Thus, the perspective is off. My internal speakers work always. Does anyone know how to solve this problem? I absolutely ideas … Oh sorry I forgot to mention. I tried to install the drivers, reinstall, Burnt the disc and reinstall drvier and none of this seems to work. ok I novelty heard that sound through my headphone jack is also very quiet. I thought he was being implemented but it is my external speakers (which are connected) it just got up
See if your Windows Vista recorgnize your sound card. Sometimes, their drivers can not work or removed by or restoration of a facility. I propose that a new update intall drivers for your sound card
