But there is no downside in using prepare callback.
The prepare callback also can be called multiple times. This certainly happens when the stream is stopped/restarted multiple times.
If something does not need to be done again when a stream is restarted, then it should be done in the hw_params callback.
Oh, forgot about that. This would suggest to keep the stream header configuration in the hw_params().
