I added the autoflush ahd its module -- still effect is the same. -- Repetings became necessary up to 7 instead up to 3 w/ the shell version.

I have no ideas what to do except to find the piece of code i have written long time ago for such a task -- that i remembere worked perfect. But do not know where the code is.

Here are the last changes:

use warnings;
use strict;
use utf8::all;
use POSIX qw( mkfifo );

mkfifo( $svitok_truby, 0700 ) || die 'Ошиб&#10
+82;а создания &
+#1090;рубы  '.$svitok_truby.'  : '.$!;
local $SIG{CHLD} = "IGNORE";

# Родитель.
if( $nomer_vosproizvodyshchego_protsessu=fork ){

  use IO::Handle;

  open( $FIFO, '>'.$svitok_truby ) || die 'Не о&#109
+0;крыть труб&#1
+091; '.$svitok_truby.' на запи&#1
+089;ь : '.$!;

  # Same thing? -- I.e. not working?
  $|=1;
  $FIFO->autoflush( 1 );

  use Term::ReadKey;
  ReadMode 'cbreak';

  while( 1 ){

    $knopka=&ReadKey( 0 );

    if( $knopka eq ' ' ){
      print $FIFO 'pause';

    }elsif( $knopka eq '0' ){
      print $FIFO 'quit';
      last;
    }
  }

# Ребёнок.
}else{
  for( $i=0; $i<=$#svitok_na_vosproizvedenie; $i++ ){
    system( '/usr/bin/mplayer -slave -input file='.$svitok_truby.' '.$
+svitok_na_vosproizvedenie_kom[$i] );
  }
}

ReadMode 'normal';
close( FIFO );
unlink $svitok_truby;
