Sorry, no etymologies found.
Friction is caused by the tongue, regardless of voice but it just so happens however that without an example of *-dhdh-, all examples of spirantization in PIE that I'm aware of simultaneously show devoicing.
Actually, come to think of it... if *ǵʰo originally meant "back (here), (left) behind" then I might get to reckoning that it's a corruption of o-graded *ǵʰoh₁ *s / _# under a common rule of final spirantization.
Sure there are examples of single-POA spirantization. *p f is found in Arabic, *k x in Mongolian, etc.
Hmm, seems like a short time-limit for devoicing & spirantization then, if they're to happen after Etruscans gain access to the alphabet.
Most Israelis say bekitá bet rather than the puristic bekhitá bet in the second grade' (note the spirantization of the /k/ in the latter); éser shékel rather than asar-á shkal-ím ten shekels' (the latter having a polarity-of-gender agreement with a feminine numeral and a masculine plural noun); aní yaví rather than aní aví I will bring'.
