Here is something basic in your ideas which I've never understood. What
does "conscious observer" have to do with "sound machine"? I understand
that an observer can be considered as a machine, but how can an observer
be sound or not sound? Soundness as far as I understand it applies to an
axiomatic theory, that is, the theory is sound if you can't deduce "false"
from its axioms. Now if you have a machine that enumerates theorems of an
axiomatic theory, maybe you can say that it's sound if the theory itself
is sound. But obviously an observer is not a theorem producing machine, so
what does it mean for an observer to be a sound machine?
