The point is snd_pcm_sw_params_set_silence_threshold return error when the
value is greater than buffer size, it is not correct to set silence threshold
to boundary


BTW, why does winealsa expect it always have commitadhead to write to the sound
card in CommitAll() since the application just issue getposition() to get the
playback position ?
