Dear All,

I have a button(key) driver including a Volume Up/Down key
controlling. I change the gain value directly by writing register value
of audio codec while the volume is pressed. Although I can change the
volume in this way, the scrolling bar of OS Desktop volume setting did
not act to corresponding volume position. How can I make the volume
scrolling icon move when I press the volume key.

call waveOutMessage( )??

I think that you may need to change the control panel applet. IIRC, it does
not assume that the volume will change from an external source, so it
doesn't check and update.
