What is the actual problem you're trying to solve? > Hello! I'm developing a "live microphone system over local network" which are user space programs (clients => server) transferring audio nearly real-time (human imperceptible latency). I need to elaborate a good solution of implementation to have everything working as expected -- networking, scheduling, IO management etc -- However I need at first make sure I can get control over audio. I decided to use ioctl() level of communication with ALSA in kernel, and what I need is synchronization :-) I must know which sample the hardware is currently processing to prevent a lot of losses or latency increasing.
