Ok, so afaict you hear a "TAK" noise at stream shutdown and want to get
rid of it. ASoC calls shutdown/close for each of it's components :-

	if (cpu_dai->ops->shutdown)
		cpu_dai->ops->shutdown(substream, cpu_dai);

	if (codec_dai->ops->shutdown)
		codec_dai->ops->shutdown(substream, codec_dai);

	if (machine->ops && machine->ops->shutdown)
		machine->ops->shutdown(substream);

	if (platform->pcm_ops->close)
		platform->pcm_ops->close(substream);

You didn't mention any struct in your last mail.

Please explain your problems more clearly in the future. It's very
difficult to help here without a good problem description or a detailed
explanation of why you need this feature.
