[Trisquel-users] Re : Why does installing Trisquel 7 updates cancel my sound system?

[lcerf]

The problem is specific to the *user*.  'apt purge' removes *system*  
configuration files.  It does not remove ~/.config/pulse (that is a folder  
named "pulse" in a hidden folder named ".config" in your home folder).  I  
would try to remove it.
