Mic fader greyed out

[Ray]

On my volume control recording dislay the mic input, CD and Line volume
faders are greyed out.
I have a Realtek High Definition Audio built into the mobo.
I have downloaded and installed the latest drivers from ASUS, but still they
are not accessible.
Can someone please help?
Thanks

Did you try and contact the Realtek Help and Support line

If the image to adjust,turn on/off,etc is all faded out,then those options
probably dont exist with youre hardware,if chk boxes only are,then those
would
be available & are,but youre configuration somewhere isnt right.
