Don't trust the user to know about them all and make sure all volume controls are unmuted and turned to max volume. If it works on the LiveCD, it's a Windows problem.Īlso, keep in mind that there are often several different ways to adjust sound on a laptop. Using an Ubuntu CD is a great way to check. You need to first determine whether the hardware is, in fact, working or whether your user had borked Windows is some manner.
Whenever I want to check if hardware is broken I tend to use a linux live cd like ubuntu and use it to check the hardware.
