There is one very general function to access the multimedia functionality of windows.

MCI_command(str) This functions sends the command string to the Windows multimedia system using the Media Control Interface (MCI). It returns the return string. You can use this to control all sorts of multimedia devices. See the Windows documentation for information in how to use this command. For example MCI_command('play cdaudio from 1') plays a cd (after you have correctly initialized it using other commands). This function is only for advanced use!
