This is a quick example. There are probably other ways to do it, but this is straight forward:

Code:

awk '
        /^[*]/ {                            # new section 
                if( snarf )
                        printf( "\n" );         # terminate the last section
                snarf = 1;                      # open the section
                n = index( $0, "-" );           # find first -
                printf( "%s ", substr( $0, n+1 ) );     # print everything after the first dash
                next;
        }

        NF == 0 { 
             if( snarf )
             {
                  snarf = 0; 
                  printf( "\n" );
              }
              next; 
       }     #terminate section on blank line

        snarf > 0 {                         # if in section print this line. 
                printf( "%s ", $0 );
                next;
        }

        END {
                if( snarf )                    # need to finish the last section with newline
                        printf( "\n" );
        }
'

It does assume that each section starts with an asterisk (*) and that if it is continued onto multiple lines the section ends with the next asterisk or a blank line. The output from each section is put on one line (no intermediate newlines) even if it was on multiple lines in the input. Each section is placed on a separate line.

Hope this helps.

DESCRIPTION

       This  tool  can	be used to introspect or reconfigure a running PulseAudio sound server during runtime. It connects to the sound server and
       offers a simple live shell that can be used to enter the commands also understood in the default.pa configuration scripts.

       To exit the live shell, use ctrl+d. Note that the 'exit' command inside the shell will tell the PulseAudio daemon itself to shutdown!

       If any arguments are passed on the command line, they will be passed into the live shell which will process the command and exit.
