these are general things that i usually ask people to do before we get into replacing the drivers. they are pretty simple but maybe they have been overlooked. i appologise if you have done them all or they seem simplistic. but sometimes very simple things get overlooked.
like are your speakers plugged in to both the sound card and the wall outlet if necessary and are they turned on if their is an on off switch and a volume control on the speakers themselves ok its a laptop probably no external speakers. if you can get your hands on a couple i would love to know if they work there should be a jack for external speakers. and there might be a physical mute button on the laptop that actually turns the speakers off
first check that the volume is not muted. in the control panel sounds and audio devices
volume tab make sure the volume is at a normal level for both the card and the speakers
and the mute is not checked.
if that is good go to audio and make sure the correct default device is in there for sound playback and music playback.
if that is good go to hardware tab and make sure all of the devices are stated to be working correctly
if they all say correct go to control panel system hardware tab device manager
one at a time highlight each line in the sound and game controller section then hit the delete button on the keyboard. untill the section is blank
then REBOOT. they should all be reinstalled automatically. hopefully working correctly
