Installed recently kernel update (4.7 now, previous 4.6.4). ELD speaker
allocation
is working without running Xorg this time.
Each time computer wakes up after a suspend I need to re-attach power cord,
otherwise
  $ cat f1/card0/eld#0.0
shows empty file. But botting up doesn't require reattaching of one.

Thanks to developers, one year old problem of mine had been partially fixed,
it's better then it was before!
