M-Audio Portman 2x4 Manual - Windows

Symptoms/Solutions
Even when the PORTMAN 2x4 passes its own diagnostic test, it is still pos-
sible that you may have other concerns. Below you will find a
questions/answers-style reference on many such topics. Before consulting

SOLUTION: What is most likely happening here is that your computer,
probably a laptop, is not transmitting information as fast as the PORTMAN

again until the box is unchecked.
SYMPTOM: When booting up Windows, I get the messages “Output
