What is Auto Volume Control?  Auto Volume Control is a function that maintains the same volume level for all digital sources. The volume level of playing music changes for each file even if the player volume is fixed. If you use the Auto Volume Control function, the volume level will remain the same. However, if the Auto Volume Control function is activated, the volume control function of a multimedia player such as Windows Media Player may appear to not work. In this case, click over the volume icon in the notification area of the Taskbar and adjust the volume by sliding the volume bar.  To disable EDS, select Enhanced Digital Sound OFF from the popup menu.  With EDS OFF state, you cannot adjust EDS options while playing music or video. Adjust the EDS options first and play the music or video then.
