The same problem occurs on Dell Latitude D600 laptop with it's default soundcard. When using Dell's soundlevel changing buttons, nice pop-up shows that sound level should be changed, but nothing happens. Changing sound level from mixer applet also works fine. Dell Latitude D600 is using Intel AC97 SoundCard.
