With my installation of SoX, running $ sox -M "|sox T72.WAV -p pad 0" "|sox T72.WAV -p pad 1" output.wav creates an output file with 6 channels, containing (in this order): 1 static 2 silence 3 voice 4 static 5 silence 6 voice so I still cannot reproduce your problem. I also tried with the "-b 24" which should be irrelevant - no change. Can you please also upload your output file?
