>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. So i am just wondering why this code is not present in the struct i mentioned in my previous mail. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
