Struggling with Midi and long repeats

[Omer Katzir]

I have this music, but when I try to make midi out of it, it doesn’t do the 
repeats. Does anyone have any suggestions on how to do it? 
I’m really struggling with lilypond lately :-( 

\version "2.22.2"


\header {
  title = “%%%%"
  composer = "Omer Katzir"
  tagline = "http://omerkatzir.net";
}



upper = \relative c' {
  \time 3/4
  \key g\major
  \voiceOne
  \tempo 4 = 90 


B b b b 


}

lower = \relative c {
  \key g \major
  \voiceTwo
 
  \repeat volta 2 { b b b b b    } 
    
    
  \alternative {
    { a a a a  | }
    { a a a a  \mark \markup { \italic "Fine"   } \bar "||" 
  }
  

    
    
  }

C d e f g a b c \mark \markup { \italic "D.C. al Fine" } 
 
 
}

\score {
  <<
    \new StaffGroup = "tab with traditional" <<
      \new Staff = "guitar traditional" <<
        \clef "treble_8"
        \context Voice = "upper" \upper
        \context Voice = "lower" \lower
      >>
      \new TabStaff = "guitar tab" <<
        \context TabVoice = "upper" \upper
        \context TabVoice = "lower" \lower
      >>
    >>
  >>
