Digg - New MacBook Sound Level is Defective

In the application "DVD Player" (the default way of playing movie DVDs on the MacBook ), you can alter the volume presets. Click on the toolbar option "Window", then select "Audio Equalizer" from the dropdown menu. On the equalizer presets, raise the selector knob all the way to the top for each of the presets (ten in all). Make sure the checkbox "On" is checked in the upper left corner. Then in the window at the upper right (probably says "Manual"), select "Save Preset" and a new window opens up.
Enter a new name like "Max Sound Preset", check the box "Use for all discs", and click on "OK".

One more thing: select the toolbar option "DVD Player", then select "Preferences". Click on "Previously Viewed". Make sure that "Always use disc settings for: Audio EQ" is checked, Click "OK" and you're done.
