If your 9220 is the same as mine, there is no APPARENT way to play an 
audio CD as it has no input. The really weird part is, however, that if 
you go into Windows and start up the CD player app, it will play the CD 
and using the CD slider on the mixer will control the volume. I always 
thought that the CD player app was using the analog input, which if true 
is really weird. Apps like VLC and Windows Media Player read the 
digital data from the drive and send it to the regular dsp, which is 
arguably better quality.
