May be you missed his post#116, he said:
"So, when I make the factory reset and I arrive at the speakers test tone....there is a sound ....not loud. When the setup is finished and I go the the meniu for the test tone....no sound....that's so wierd......."
So he seemed clear that was the only time he could hear the sub, presumably sub1. The only part that is still not totally clear is whether "and I arrive at the speakers test tone" referred to during auto setup, i.e., running Audyssey.
If it is, then
@comunicator2009 should repeat that process one more time and when he "arrive at the speakers test tone" again for the sub1, turn the subwoofer's volume dial up (the one at the back of the sub) and see if the level heard would go up.
