[alsa-devel] snd_pcm_format_set_silence parameter

Mates,

What exactly does snd_pcm_format_set_silence is useful for???

That is the code:

if (count < chunk_size) { snd_pcm_format_set_silence(hwparams.format, data + count * bits_per_frame / 8, (chunk_size - count) * hwparams.channels); count = chunk_size; }

Could I get some help? Thanks
