Once we've set-up the HDA stream and its format, we currently don't support additional format changes. We already have a protection in the .prepare case, but this needs to be added in the hw_params too. In mixing use cases where two DPCM FEs are connected to the same BE, if can happen that there are multiple calls to the BE hw_params when the two FEs are configured simultaneously. This could alternatively be fixed at the DPCM level but that's a more intrusive change requiring infrastructure changes: this would need to be paired with the definition of fixed hw_params at the mixer level.
