I'm not sure what you mean by channels.  I assume you're referring to 
"streams of audio data," but if not then correct me...

A buffer stores audio data.  If you are streaming, you'll put the audio 
data into buffers, and queue them together to make a continuous stream 
(or multiple continuous streams).

A source is an object which contains one or more buffers, and can have 
3D properties such as position, velocity, etc.  All sources also have 
other properties such as gain.

An illustration -- For minimal playback in OpenAL, the following will 
produce audio:
    1) create a buffer
    2) put audio data in the buffer
    3) create a source
    4) attach the buffer to the source
    5) call alSourcePlay on the source
