switch_audio -1 does nothing.

switch_audio -2 (-3, -4 ...) does what slave.txt says: switch to the next 
audio track, like switch_audio alone does.

-demuxer lavf is even worse. First it gives a lot of error messages, like 
these:

switch_audio id, still not work. And switch_audio -2, gives no sound.
