      When a jukebox playing music is broken, the music initially stops, but when I opened up my inventory then closed it again, the song plays again. This works with any disc in creative and survival, and in both single- and multiplayer.

      1. Get Jukebox and disc of any kind
      2. Play the disc
      3. Break jukebox BEFORE song ends
      4. Open your inventory
      5. Close Inventory
      6. Song plays without a jukebox

      More generally, sounds can replay when a GUI is closed, when they shouldn't. This includes block breaking sounds, button sounds, and music. It also includes any GUI closing besides the pause menu in single player – your inventory, the chat GUI, or a chest all work.

      Debug info

      I recently figured out how to get minecraft to output sound debug logs by following this wiki.vg tutorial. Using the following configuration: 

      <?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN" packages="net.minecraft,com.mojang">
    <Appenders>
        <Console name="SysOut" target="SYSTEM_OUT">
            <PatternLayout pattern="[%d{HH:mm:ss}] [%t/%level]: %msg%n" />
        </Console>
    </Appenders>
    <Loggers>
        <Root level="debug">
            <filters>
                <MarkerFilter marker="SOUNDS" onMatch="ACCEPT" onMismatch="DENY" />
            </filters>
            <AppenderRef ref="SysOut"/>
        </Root>
    </Loggers> 
</Configuration>

      This is what the logs look like when the bug is reproduced:

      For 73f94183-6a17-4355-b356-2374cd71ed68, I was mashing open/close inventory (which is how the bug is reproduced). As you can see, it's getting resumed multiple times, despite never getting paused. It only replays the sound once (since resuming the sound is simply playing it again), but probably the sound is getting played before it is removed.

      Programmatic cause

      Note: MCP names for Minecraft 1.8 (mcp910) are used here. Obfuscated names as of 1.9-pre1 appear at the bottom.

      The reason that this bug occurs is that sounds are replayed whenever a GUI is closed. The most likely reason why sounds were replayed is that they are paused when certain GUIs open (such as the ingame pause menu) in single player. However, the sounds are played even if they were never paused (IE, they are played when any GUI is closed).

      net.minecraft.client.Minecraft, lines 964 - 1005
      /**
 * Sets the argument GuiScreen as the main (topmost visible) screen.
 */
public void displayGuiScreen(GuiScreen guiScreenIn)
{
    if (this.currentScreen != null)
    {
        this.currentScreen.onGuiClosed();
    }

    if (guiScreenIn == null && this.theWorld == null)
    {
        guiScreenIn = new GuiMainMenu();
    }
    else if (guiScreenIn == null && this.thePlayer.getHealth() <= 0.0F)
    {
        guiScreenIn = new GuiGameOver();
    }

    if (guiScreenIn instanceof GuiMainMenu)
    {
        this.gameSettings.showDebugInfo = false;
        this.ingameGUI.getChatGUI().clearChatMessages();
    }

    this.currentScreen = (GuiScreen)guiScreenIn;

    if (guiScreenIn != null)
    {
        this.setIngameNotInFocus();
        ScaledResolution var2 = new ScaledResolution(this, this.displayWidth, this.displayHeight);
        int var3 = var2.getScaledWidth();
        int var4 = var2.getScaledHeight();
        ((GuiScreen)guiScreenIn).setWorldAndResolution(this, var3, var4);
        this.skipRenderWorld = false;
    }
    else
    {
        this.mcSoundHandler.resumeSounds();
        this.setIngameFocus();
    }
}

      When guiScreenIn is null, mcSoundHandler.resumeSounds is called. The SoundHandler methods simply call the same methods on the SoundManager.

      net.minecraft.client.audio.SoundManager, lines 467 - 495
      /**
 * Pauses all currently playing sounds
 */
public void pauseAllSounds()
{
    Iterator var1 = this.playingSounds.keySet().iterator();

    while (var1.hasNext())
    {
        String var2 = (String)var1.next();
        logger.debug(LOG_MARKER, "Pausing channel {}", new Object[] {var2});
        this.sndSystem.pause(var2);
    }
}

/**
 * Resumes playing all currently playing sounds (after pauseAllSounds)
 */
public void resumeAllSounds()
{
    Iterator var1 = this.playingSounds.keySet().iterator();

    while (var1.hasNext())
    {
        String var2 = (String)var1.next();
        logger.debug(LOG_MARKER, "Resuming channel {}", new Object[] {var2});
        this.sndSystem.play(var2);
    }
}

      Note that resumeAllSounds works simply by calling play on all of the currently playing sounds. This works in most cases, as calling play while a sound is currently playing doesn't do anything. However, if the sound has finished playing but has not been cleaned up yet, calling play on it will cause it to play again, from the start. This is the core cause of this bug.

      The simplest way to fix it is to create a list of sounds that were paused when pauseAllSounds is called, and then only play the sounds in that list when resumeAllSounds is called (and then clear the list).

      Something like this:

      Replacement for code in net.minecraft.client.audio.SoundManager
      private List<String> pausedSounds = new ArrayList<String>();

/**
 * Pauses all currently playing sounds
 */
public void pauseAllSounds()
{
    Iterator var1 = this.playingSounds.keySet().iterator();

    while (var1.hasNext())
    {
        String var2 = (String)var1.next();
        logger.debug(LOG_MARKER, "Pausing channel {}", new Object[] {var2});
        this.sndSystem.pause(var2);
        
        pausedSounds.add(var2);
    }
}

/**
 * Resumes playing all currently playing sounds (after pauseAllSounds)
 */
public void resumeAllSounds()
{
    Iterator var1 = this.pausedSounds.iterator();

    while (var1.hasNext())
    {
        String var2 = (String)var1.next();
        logger.debug(LOG_MARKER, "Resuming channel {}", new Object[] {var2});
        this.sndSystem.play(var2);
    }
    
    this.pausedSounds.clear();
}

      (It may be necessary to make pauseAllSounds and resumeAllSounds synchronized depending on if it's called from a separate thread, but I'm guessing not since it isn't currently needed; also, don't blame me for the ugly syntax there; that's MCP's fault)

      I've tested this and found that it eliminates all of the looping sound issues, which is the main part of this bug.


      Here are the code snippets from above with 1.9-pre1's obfuscation (jd is used to decompile):

      The place where resumeSounds is called in displayGuiScreen:

      bce, lines 864 to 893
        public void a(bfa ☃) {
    if (this.m != null) {
      this.m.m();
    }
    
    if ((☃ == null) && (this.f == null)) {
      ☃ = new bfh();
    } else if ((☃ == null) && (this.h.bP() <= 0.0F)) {
      ☃ = new bel(null);
    }
    
    if (((☃ instanceof bfh)) || ((☃ instanceof bgq))) {
      this.u.aq = false;
      this.r.d().a();
    }
    
    this.m = ☃;
    
    if (☃ != null) {
      p();
      bcw ☃ = new bcw(this);
      int ☃ = ☃.a();
      int ☃ = ☃.b();
      ☃.a(this, ☃, ☃);
      this.s = false;
    } else {
      this.aL.e(); // This is resumeAllSounds, line 890
      o();
    }
  }

      Here is the code for resumeAllSounds and pauseAllSounds:

      byu, lines 409 to 421
        public void e() {
    for (String ☃ : this.i.keySet()) {
      b.debug(a, "Pausing channel {}", new Object[] { ☃ });
      this.f.pause(☃);
    }
  }
  
  public void f() {
    for (String ☃ : this.i.keySet()) {
      b.debug(a, "Resuming channel {}", new Object[] { ☃ });
      this.f.play(☃);
    }
  }

      And here are resumeAllSounds and pauseAllSounds with the bug fixed:

      byu
        List<String> pausedSounds = new ArrayList<String>();
  
  public void e() {
    for (String ☃ : this.i.keySet()) {
      b.debug(a, "Pausing channel {}", new Object[] { ☃ });
      this.f.pause(☃);
      pausedSounds.add(☃);
    }
  }
  
  public void f() {
    for (String ☃ : this.pausedSounds) {
      b.debug(a, "Resuming channel {}", new Object[] { ☃ });
      this.f.play(☃);
    }

    pausedSounds.clear();
  }

      Obfuscation as of earlier versions can be found here.

      There are other ways it could be fixed, but this is the simplest way.

      Some additional oddities with jukeboxes that aren't necessarily part of this (from MC-35896):
      a) In survival mode, ejecting a disc while breaking the jukebox block may make the jukebox music permanent (Goes off after exiting the world). (Both survival and creative mode). (separate bug?)
      b) Sometimes, when destroying the jukebox block (After a) ALL music can go off (Not any music until exiting Minecraft). (Creative mode).
      c) Sometimes, when playing jukebox exiting the world, jukebox music can stay on (Does not go off until exiting Minecraft). (Creative mode).
