problem with audio. advanced help needed

Here is my problem: my friends brother is sum it-guy and he configurated my friends computer somehow in ms-dos( command line). he has windows xp.
Friend told me,that his brother messed smthing in command line and now his computer shows that no audio card has been installed at all. before he could listen music and do all the tasks requiring audio,but now it shows in control panel that no audio card installed.
Does anyone know somekind of command that can enable/disable audio card in cmd??:stare:

Tell him to go to System properties->Device manager, then scroll down to sound, video and game controllers. Then reset the adapters or right click them and choose update. That should do it.
