Ok, I think I'm going to close this thread, as I figured out that the issue arise from not powering the mixer device first of all. Unfortunately the power control was last one in the list, so initialization of HAL failed all control settings, until last one (power) was reached. I patched audio_route.c to force power first and now everything goes fine... looks like.
Thanks all for the contributions!
