I have an acer aspire 5100 and the audio does not work! i had to reinstall windows xp and format the C drive, so basically lost it all =( My sound doesnt work, i have downloaded and installed the driver from the acer website but still no sound! When i start up my laptop a 'new hardware" message comes up for the PCI device (im guessing for the sound) but i dont have a CD for it. Is this my audio problem? any help would be appreciated!
