Try this code and verify if you are getting desired output:-
Code:
grep "^#" config-file.conf | sed 's/#//g' | while read line
do
        grep -v "${line}" blacklist-sound.conf
done

If yes, then you can redirect the output to a temporary file and rename it back to original file: blacklist-sound.conf

cgsnapshot

CGSNAPSHOT(1)							 libcgroup Manual						     CGSNAPSHOT(1)

NAME

       cgsnapshot - generate the configuration file for given controllers

SYNOPSIS

       cgsnapshot [-h] [-s] [-t] [-b file] [-w file] [-f output_file]  [controller] [...]

DESCRIPTION

       cgsnapshot  generates the cgconfig compatible configuration file for the given controllers.  If no controller is set, then cgsnapshot shows
       all mounted hierarchies.  The output is in the same format as the cgconfig.conf configuration file.

       -b file
	      Display only variables from the blacklist.  The default location of the blacklist is /etc/cgsnapshot_blacklist.conf.  This list con-
	      tains  all  variables  which should be ignored by the cgsnapshot If the variable is blacklisted, it will not be displayed.  If it is
	      not present on the blacklist, the whitelist is checked.

       -h, --help
	      display this help and exit

       -f, --file
	      Redirect the output to output_file

       -s, --silent
	      Ignore all warnings

       -t, --strict
	      Do not display the variables which are not on the whitelist

       -w file
	      Set the blacklist configuration file.  This list contains all variables which should be displayed by cgsnapshot If the  variable	is
	      not  blacklisted,  the  whitelist is checked.  If the variable is on the whitelist, it is displayed by cgsnapshot If the variable is
	      not on the whitelist, the variable is displayed and a warning message is produced.  By default the whitelist is not used.

	      The warning message can be omitted using the -s, --silent flag.  If the -t, --strict flag is used, the variable which is not on  the
	      whitelist is not displayed.

       controller
	      defines the controller whose hierarchies will be output

ENVIRONMENT VARIABLES

       CGROUP_LOGLEVEL
	      controls verbosity of the tool. Allowed values are DEBUG, INFO, WARNING or ERROR.

FILES

       /etc/cgsnapshot_blacklist.conf
	      default blacklist

       /etc/cgsnapshot_whitelist.conf
	      default whitelist

       /etc/cgconfig.conf
