Thanks, Lou.  As long as I do straight 1:1 channel mapping, and don't try to combine two channels into one, I don't seem to experience the audio clipping and distortion.  And from my (admittedly limited) testing it appears that 1:1 mapping is the correct thing to do.  But that is good to know, and I will keep it in mind in case I encounter any other unusual situations such as this.
