So, from the above we think that period elapsed event derived in the described ways may not improve latency and will complicate the system. So, for that reason we are thinking of the option 2) (Positions of actual data transmission
in any serial sound interfaces of actual hardwares.)

Please declare the way to enable stuffs on DomU to get the positions from actual hardware.

This is what we haven't investigated yet in detail as we were mostly focusing on
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 actual
hardware 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 developers
in 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?

Regards

Takashi Sakamoto
Thank you,
