i am having the exact same problem and i have the ultimate version. under the tools drop down menu there is a preference tab that allows you to modify the audio “volume adjust” setting. i believe mine was defaulted at “3”. i’m now attempting to rip a dvd with the setting at “1”.
i tried setting it at “0” thinking that any number would amplify the sound, causing it to become distorted, however, when i did that i got no sound at all.
