ANALYZER-IMFAudio-UnsupportedChannelMapping (Audio Channel Mapping is not supported)
IMF audio requires Channel Mappings [LT,RT] or [L,R,C,LFE,LS,RS] but found Channel Mapping (L,C,R,LS,RS,LFE)
The channel mapping used does not adhere to the channel layouts/configurations supported within our delivery specifications. As such, the audio track cannot be processed because the channel mapping/order is not supported.
Check the contents of the file, ensuring that no extraneous audio channels have been included, for example, music & effects, and that no channels have inadvertently been removed resulting in an unsupported number of channels. If the contents of the channels are in the wrong order or there are missing or extra channels then you will need to generate a new audio track in accordance with our delivery specifications.
