Does SOF support the full resume? That is, the stream gets resumed at the exact position that was suspended. Most devices can't, hence they don't set *_INFO_RESUME flag and let user-space restarting.

Not atm, and I don't see this as an ask in the near future either, but it's technically possible given the open firmware.
