However this part: Delay is distance between current application frame position and sound frame position. suggests that it indeed can be zero. Or why would a soundcard have a gap between the read and write positions if it has played everything? If Wine uses a wrong assumption, then please clarify the function description. > Is there perhaps a more appropriate API call they can use to do whatever > test they are doing? What Wine needs to know, is whether a particular sample has already been played or not. It does 'bytes_written - delay_in_bytes' to find out how much of the written data the soundcard has already played. If there is a better test for it, please explain. tom _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
