Monitors allow you to hear what is coming out of a speaker (think of a 
band playing at a live gig, they use monitors to hear their own 
playing). So for every output sink there is a "monitor" source that goes 
with it.

If you were to record from a monitor and then play some audio you should 
hear that coming back in.

It's odd that things are not working tho' :s Perhaps the live CD uses 
tsched=0 mode in it's default.pa? The output from pacmd list again on 
the live cd should provide a good comparison.
