I just bought a Thinkpad X1 Carbon 20BS with Windows 7 and the sound quality in headphones is just terrible. No bass and a lot of strange noices. I updated the bios via BIOS update utility and also installed the realtek HD audio driver. It had almost no effect. I tried uninstalling the drivers and using the default Windows drivers which gave even worse sound quality. I don't have the Dolby* tools installed and I also uninstalled Realtek Audio manager and only updated the driver manually. I also tried drivers from realtek.com directly with no luck. Any ideas what else should I try?
