I've a Lenovo Y550 laptop with dual boot Ubuntu 12.04 and Windows &. I've installed Realtek High Definition Audio Codecs in windows installation. When I hear audio in Ubuntu it has less effect than Windows. In Ubuntu I am using the default installation settings. Is there anything I can do to make it better?

go to and download the driver for UNIX/Linux

Then go to the downloaded location and extract the file.

Inside that folder, there's a file named INSTALL, double click it and when prompted click run in terminal.

Finally Reboot.
