I've been having this problem ever since I installed Windows 7 onto my machine to upgrade from Vista.
The speakers produce heavily distorted audio and I have been unable to fix it at all.
I have a Realtek Integrated HD Audio sound card, but installing the drivers
will not overwrite the stock Microsoft drivers.
I cannot figure out how to fix this issue and I am beginning to think that Windows 7 just has issues which nobody's bothered to address.
I would appreciate any help.
