Hi, I can't post the source code, but I can post the algorithm: We have input and output synched. The inputs are set to non-blocking behavior while the outputs are not. The loop grabs input, and does any processing it needs to. After that, it detects if any of the streams are behind more than a period, and snd_pcm_forwards them a period length if so. It then writes the waiting buffer to the blocking outputs. readi/writei is the mechanism used. I have tried also grabbing the readi input into a buffer and passing that immediately to writei with no change in latency.
