Hello All, I am interfacing the ICS43432 MEMS microphone with McBSP interface. The data sheet of the ICS43432 microphone shows that it takes about 4.5ms (16kHz sampling rate) for startup. Because of this, I hear a transient noise at the beginning of every stream. Is there in any way I can discard the frames inside the kernel space itself before reading the samples using snd_pcm_readi() call? I was able to mute the first few frames after the readi() call, but would want to know if I could do it before the readi() call itself inside the kernel space. Appreciate any help! Thanks, Ankhit _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
