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)
You mean that any alsa-lib or libpulse applications run on Dom0 as a backend driver for the frontend driver on DomU?
No, the sound backend [1] is a user-space application (ALSA/PulseAudio client) which runs as a Xen para-virtual backend in Dom0 and serves all the frontends running in DomU(s). Other ALSA/PulseAudio clients in Dom0 are also allowed to run at the same time.
