So, for that reason we are thinking of the option 2) (Positions of actual data transmissionin any serial sound interfaces of actual hardwares.)Please declare the way to enable stuffs on DomU to get the positions from actual hardware. period elapsed approach, so we can report our findings to the community.Taking into account the fact that the backend we have is a user-space application running on top of ALSA/PulseAudio we cannot get HW pointers from actualhardware by any means (PulseAudio use-case is the most tough thing in equation) At the moment we are seeking for any advise from more experienced developersin the field on possible ways to solve the problem of Dom0/DomU synchronization. Hope, together we can identify such a way that would be accepted by the community. If you have something on your mind could you please share your thoughts?
