Instead of using a custom cfg with an extra "audio filter". i_chan_mode is already used by "audio converter" for dolbystereo. The spatialaudio "audio filter" is converted to an "audio converter". Such type of modules are loaded automatically when a conversion is needed (the chan_mode conversion). Since this module is now an "audio converter", don't override in/out fmt, but test for in/out fmt compatibility.
