I.e. If I write a sample to the buffer now, it will play on the speakers in X samples time. In this way, if I have a sample that must play in X samples time, I write it now. If I have a sample that must play in X+3 samples time, I add 3 samples of padding first. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
