To get TrueHD/Atmos passthrough in music player (paplayer) working should simply be copying https://github.com/xbmc/xbmc/blob/master...#L363-L366

into this block of code https://github.com/xbmc/xbmc/blob/master...#L501-L519

Following what fristch did for DTS-HD in https://github.com/xbmc/xbmc/pull/16027

If nobody else has the time, I can maybe raise the code change but it won't be before the weekend.
