It is the normal mode of operation for memory-mapped IO. The only thing that could change the delay is your application taking too long to process the data to meet the deadline (xrun). In this case you'd probably enlarge the total delay by a factor two until a cycle is long enough to process or you exceed the maximum buffer size supported by the hardware. If I'm not mistaken most cards support audio cycles of 2048 frames, for a software-through latency of 4096 frames. On the ice1712, this is the upper limit. tim ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
