What are you trying to do ?

There was a "TAK" noise because of non-presence of this code. This soc_shutdown calls the respective shutdown code in codec for prevention of this kind of strange noise.In my code it is turning off the Amplifier because of which i no longer get the "TAK" sound.

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);

So i am just wondering why this code is not present in the struct i mentioned in my previous mail.

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.
