Since the earlier discussion, pulseaudio was here.  Another layer of 
complexity without solving the identity problem, for me at least.  

Yesterday I removed pulseaudio according to the principal: if no 
special cases make sense, tackling the more complex problem is 
premature.

Thanks,                              ... P.
