Help with Cakewalk knowledge base and my Sonar LE

In Cakewalk.com/Support/Knowledge-Base/2005260/Audio-Tutorial-setup-Record-Playback I came across a problem.

 
Where it says "Let's set-up a track for recording digital audio:"
 
"3.In the track's Output field, click the dropdown arrow and select an audio output from the menu. You will usually choose 1 & 2, because these are most commonly the outputs that speakers or audio monitors are connected to.
4.In the track's Input field, choose the audio input that your instrument or microphone is connected to. If you would like to record a stereo track select "stereo". Some audio interfaces refer to their stereo inputs as pairs, like 1/2, 3/4 or 5/6. Most often left channels are represented by odd numbers and the right ones are represented by even numbers."

 For number 3, In my Sonar LE program, in the track's output field, when I click the dropdown arrow near where it says EDIROL UA-25 UA-25 WAV, a short list saying the words  ...None... and New Stereo Bus comes up in a drop box. There is no menu for me to select anything else.
 
For number 4, in the track's input field it says the word ...none..., and when I click it the drop box says the word None with a tick next to it, and underneath it it says EDIROL UA-25 (1 in, 1 out). There is no menu for me to select anything else.  
 
Someone suggested that I go to Edit > Preferences to the Audio section and choose input and output drivers. But this is wrong, there is no "Preferences to Audio section" in Edit.
 
Is there anyone out there who can help me with this? I'd really appreciate it.
