Why is the Equalizer not working when I play a CD?
If your RealPlayer is set for Analog CD playback, the Equalizer won't work when you play a CD. To fix this, set your CD playback to Digital:
1. Click the RealPlayer logo in the upper left, then Preferences.
2. In the Category pane, double-click CD, and then click Advanced CD.
3. Under Play CD Method, click Digital.
4. Click OK.
5. Restart the application.
Please see the Equalizer article for more information on using this feature.
