volume controls in windows

Hi; When i click in the "speaker icon" besides the clock, I can see the controls for microphone, speakers , cd player, volume control, synthetyzer,wave.
But when I click in the advance tab for microphone and volume control, I can not adjust the bass and treble for them (they are grayed). What do i need to do to be able to adjust them?.
Also, How can I put the "advance" tab for speakers, cd player, synthetyzer, wave?. I do not have them.
win 98
thank you for your help and time.

¡Hola, caraloca!

If your graphics card driver software does not support it, then the settings to control bass and treble will not be enabled. Not all device controls will have 'Advanced' buttons and they will not be present unless it is supported.

Here is how to show volume controls:

• 'Master Volume' window > 'Options' > 'Properties'
• Under 'Show the following volume controls:', check the boxes for the controls you wish to see present/uncheck those you do not
• Click 'OK'
• 'Master Volume' window again > 'Options' and click 'Advanced Controls' to put a check next to if there is not one already present.

Any item supported will have their respective 'Advanced' button present.
