My new Dell XPS8940 has the Realtek high definition driver an Maxx Audio Pro utility installed from the factory.

The previous iterations in my older Dell PC's (XPS8500, XPS8700, Inspiron 17 (5749) Laptop) all had an enhancements tab in the Realtek devices properties window in the Sound Devices control panel, and it included an option to make "equal" audio levels (works great on YouTube where audio levels on the videos vary greatly). No such tab is available on my new PC, nor can I find any control in the MaxxAudio control GUI. I've tried reinstalling/upgrading the drivers for both and that was no help.

Is there an option somewhere I haven't found or is this just an over-site by whoever created the driver and the utility?
