Re: Speaker sound problem
Well you would need to start by making sure the problem does come from the speakers.
By the way, speakers don't have drivers.
A simple test is to use headphones and check if the sound's fine or not.
Once you confirm that the problem is with the sound card (as I expect it will be), uninstall your current driver from the device manager, get the latest driver from the manufacturer's site and install it. Do not reboot or scan for hardware changes in the process!
