hi there, new to this forum
one day i turned my vaio off, and left it , 24-48 hours later i came back, booted it up (no problems) then when i got to the desktop, the sound icon in the system tray had a cross through it, so i tried to unmute it, but it wouldnt let me, so, i tried playing some music, but windows media player told me that it had playback issues because there was a "problem with the sound device"
so i decided to check the "sound" menu in the control panel (before i continue, the vaio has a sound card connected to the internal speaker, headphone socket and microphone socket, and a seperate device for the optical output), in the menu, the optical device was shown and works fine, it even indicates when it receives sound on the wave indicator next to it, so it is working (activating the divice turns lets windows media player work again, and makes the system tray sound icon return to normal, but i don't use this audio output so it is usually off), however, the main sound device does not appear in the sound menu, so i thought the device manager will tell me if there's a conflict, so i headed to the device manager
after loading the manager i headed to sound devices and i saw a device error indicator next to the "SigmaTel High Defenition Audio CODEC", after checking its properties, the device status shows "This device cannot start. (Code 10)".
this leads me to a dead end, i am attempting system restore as we speak, but apart from that (windows says the driver is up to date), i have no clue what to do
many thanks if you can help, 
Ian
