The shipping examples that go along with LV for analog input and output should work with your board without a problem. Furthermore, you should check the analog output channels in MAX, by using the Test Panel Resource (Analog Output) of the board and generating either a DC or Sine Wave voltage, which you can read back in the AI channels. If you still read noise out of the AO channels directly from MAX, you should contact NI tech support.
Hope this helps.
Aguila.
