[LAU] mpv af channelmap help

Hey hey, I've been trying to insert an audiofilter in mpv, through the commandline and failed miserably. Can you help? the only thing I wished to do is reverse the stereo channels, because my amp is actually plugged in the wrong way round and I can't change it. From my understanding of the help I typed: mpv --af channelmap:map="0,1,1,0":channeml_layout=2 file.wav The channelmap can't be parsed. Whatever I do. I can get a mono output with just one number. I also get some output with two numbers seperated by a dash "-", but no more. I also tried just giving two comma seperated numbers, i.e. only the new order of the input channels. I'd be grateful for a working example. My shell is bash.
