The format on the codec's bus has almost nothing to do with the ALSA
sample format.
The Sxx_xE format describes how the samples are formatted in memory,
i.e., how the DMA controller expects to read them.

.wav files do no use ALSA sample formats.
Please describe the values of the header fields in this .wav file.

That depends on the DMA controller. Most use 32-bit alignment for
24-bit samples.
