oops had a related problem.

I had another machine not on the internet so I copied  a  download of pulse 
from GIT  and did an installation.:-  
i---- beforehand I   purged it if pulse-0.9.21/ consolekit and 
hal)
ii----I noticed that symlinks to   the Makefile in the base direcory pf pulse 
were missing so I replace these
iii---I  I recompiled  kdemultimedia also.  On  restart I obtained sound on 
the   second login but none subsequenty and cdrom sound  is practicly mute   ~ 
a tenth as loud as  a hungry mosquito.
