[alsa-devel] Use of snd_pcm_format_set_silence

Hello,

I have an application where in I need to silence the first few samples of the buffer that is read from snd_pcm_readi(). In order to do this, I call the snd_pcm_format_set_silence() providing the same buffer that the snd_pcm_readi() reads to.

1) By doing this, is there going to be a timing delay due to the use of snd_pcm_format_set_silence()? 2) Is snd_pcm_format_set_silence() the correct function to achieve this goal or are there better methods? Please do let me know.

Thank you, Ankhit
