here is the link of driver available for vista

ftp://ftp.work.acer-euro.com/notebook/aspire_4720/vista/Drivers/AUDIO_Audio%20Driver_v6.0.1.5413_Vista.zip

so download the fix first and installed the driver;here is the link

Audio/volume problem


First, go to control panel - > Audio devices, then right-click any empty spot on the sound device, and show disabled or disconnected devices. If "Speakers" shows up, right-click and choose set as default (or something similiar). If this does not work, just reinstall your audio drivers. Right-click my computer -> Properties -> Hardware - > Device manager - > Sound, then find the sound cards manufacturer name, and right-click an press uninstall.
