In order to have a full mapping between channel positions in the audio stream and loudspeaker positions, the channel-mask alone is not enough: the channels must be interleaved following some Default Channel Ordering as mentioned in the WAVEFORMATEXTENSIBLE[1] specification. As a Default Channel Ordering use the one implied by GstAudioChannelPosition which follows the ordering defined in SMPTE 2036-2-2008[2]. NOTE that the relative order in the Top Layer is not exactly the same as the one from the WAVEFORMATEXTENSIBLE[1] specification; let's hope users using so may channels are already aware of such discrepancies.
