Car depuis plus de 5 ans que j'utilise kodi il ne m'a jamais posé de problème sur aucun type de fichier, ni aucune piste audio (de la stéréo aux formats audio HD les plus récents, du fichier avi au mkv x265). A mon avis tu as un problème de configuration/installation/utilisation c'est pas possible autrement.
3.1 Format support
XBMC/Kodi can be used to play/view all common multimedia formats through its native clients and parsers. It can decode these audio and video formats in software or hardware, and optionally pass-through AC3/DTS/HD audio, or encode to AC3 in real time from movies directly to S/PDIF digital output to an external audio-amplifier/receiver for decoding.
