The program does run the mainloop, using pa_mainloop_iterate in a few
places. And sink_input_index is given on the command line anyway, not
queried from anywhere. To me it looks like the program is pretty
correct. I can verify that it really records the mixed audio, though. I
wonder if the separate stream monitoring feature has broken at some
point - I think it's not widely used.
