K3B will work, I used it a couple of weeks ago to rip some xmas CDs we picked up over the holidays.

I think the trick was to put the audio CD in, start K3B, and then click on the CD icon in the left top window
area. Then you should see stuff in the right top section where the songs are listed and some controls
should be visible for copying the files to disk. If you've got an mp3 encoder you can even burn some
mp3 while you're at it.

Cheers.
