I think channel mapping is a bit of a black art. You may need to specify 
your own channel map when loading the alsa source.... although as you 
are using a monitor, you perhaps need a "remap source" module loaded 
(which is a shame as AFAIK, there is only a remap-sink module right now!).

All that said, as it presumably works fine for output, you'd expect that 
recording from the monitor, you'd get a file that you could then output 
properly.

That said, I've had issues with oggs before where they get the mapping 
wrong :s
