I ran into an issue during my test.
For I2S, an error is returned by create_iec958_consumer for 32-bits
stream (SNDRV_PCM_FMTBIT_S32_LE).
I suppose that it makes sense to handle 32-bits configuration for I2S
(but also SPDIF), to support software IEC958 formating/pre-formating...
To fix issue, just need to add 32-bits with 24-bits case in
create_iec958_consumer

Arnaud
