MI2: Two soundtracks playing at once
|Reported by:||SF/forge017||Owned by:||BenCastricum|
|Cc:||Game:||Monkey Island 2|
I have somehow gotten myself into a situation where there are two soundtracks playing at once. One soundtrack is stuck in an endless loop. It repeats every 20-30 seconds or so. It is the same soundtrack no matter where I go in the game.
As I move about in the game, the primary track changes with the appropriate area of the game. The secondary looping track stays constant and ends up interfering with the track that's supposed to be present.
I'm not sure how I got myself into this bug. I have not been able to reproduce it. I have tried every setting I can think of, but every time I load up the saved game, the problem persists. Saved game attached for your examination.

Can you remember approximately where you were in the game when the one track started endlessly looping? Do you recognize the track, or can describe it in any way? If you were to hear the track again, would you recognize it?
If the answer to the last question is "yes," you can use the iMuse debugger commands to iterate through the soundtracks in the game and listen for the one that you were hearing over and over.
Hit Ctrl+D to pull up the debugger window. Type "imuse play #" where # would start at 1 and go upward. After it says it has attempted to start track #, exit the debugger (Ctrl+D again, I believe, or type "exit") and listen to the music. Note that some track numbers will not produce music, or may only be very short sound effects. Then go back to the debugger, type "imuse stop all" to silence everything, and repeat again with the next track number.
Any additional information of the sort requested above may help us home in on the part of the game where the problem started. Otherwise, since you cannot reproduce it and nobody else has reported such a problem, there would be very little we could do to determine where to start looking.

I just noticed the same problem with the 0.6 release on Mac OS X. I was using the Quicktime driver. The place where this started happening was when you first land on Booty Island, and then either go in a building or change to the main Booty Island map. I returned to Scabb Island and the issue of two soundtracks persists.
Also, I tried debugging as you mentioned - I couldn't figure out the track number, but I know it happened also after going to the spitting contest area. I will try messing around with it more and see what happens.
Finally, I tried loading a save game before that point and playing through, trying to repeat, but I didn't get the double track effect.
Hope that helps

I remember having the very same problem - when I played the game many years ago on my DOS computer!
It also appeared on Booty Island, and it was the very same thing - one song kept playing in an endless loop, while the others worked as they were supposed to.
THIS WOULD MEAN THAT THE BUG IS IN THE ORIGINAL GAME CODE, NOT SCUMMVM!
I don't know what I did when I had this problem - I suppose I just stopped playing...
Hope this helps a bit, Matthias.

Seems that there is no easy way to reproduce this and maybe even it is only savegame in the world with this iMUSE internal state inconsistency.
What is the status of this item?
comment:7 by , 18 years ago
Well, there are at least two people who independently reproduced the problem. We never figured out a particular reason why this occured; it might indeed be a bug in the iMuse save/load code, but nothing is known.
The fact that this is hard to reproduce of course is sad, but doesn't mean this isn't a bug, I am afraid :-/

There used to be a problem, which I could only ever reproduce when running the game in fast mode (Ctrl-F or Ctrl-G) and moving quickly between rooms, that could make two pieces of music play at the same time.
I think what happened was that the game tried to start a new piece of music while one old piece of music was already fading down and yet another one was fading up. The game would try to stop the current music, but it never expected that there could be more than one current piece. I guess it picked the already fading-out music to stop, and let the fading-in music continue.
I vaguely remember trying to fix this problem long ago, but I also have an even vaguer memory of this fix causing subtle problems in some other case, so I don't know what the current status of it is. I tried reproducing it now, but the worst problem I managed to provoke was being on the Scabb Island overhead map without any music at all.
From what I remember, this fade-in/fade-out logic is all scripted. Of course, our iMUSE implementation could differ subtly from the original...

Just for reference:
Claims to be a way to reproduce it. I'll quote (MusicallyInspired) here in case something goes wrong with our forums in the future:
I know exactly how to reproduce one version of this bug. What you do is go to woodtick, let the music play for a bit, then exit to the map screen and immediately click on Cpt. Dredd's ship. What I believe happens is the transition cues up from Woodtick to the Scabb Island theme but because you've clicked on Cpt. Dredd's ship so fast the game never got time to get the cue for the transition signal to end the Scabb Island theme because technically the Scabb Island theme wasn't even started yet (only the transition to it from the Woodtick theme) and thus the Scabb Island theme plays forever until you come back to Scabb Island and leave again giving it time to end its transition. To prevent this from happening, just wait until the Scabb Island theme actually starts when you leave Woodtick before going to Cpt. Dredd's ship.
Hope that makes sense. This happens to me every single time.

Thanks to MusicallyInspried, we may finally have a reproducable test case for causing two songs to play at once:
"I know exactly how to reproduce one version of this bug. What you do is go to woodtick, let the music play for a bit, then exit to the map screen and immediately click on Cpt. Dredd's ship."
Though it's not 100% clear from his description, I assume this is a bit into the game, when the ship is anchored right beside Woodtick on the map, so you can get there almost instantly. At least, that's how I was able to reproduce it myself. That would fit with the "changing music too often, too quickly" theory that I had only seen in fast mode, a long time ago (in a galaxy far, far away).

Oops, somehow I missed LordHoto's post about it. I plead incompetence. :-)

I did encounter this problem, I and I was nearly ripping my hair out about it! Mostly because It took me several hours to even find someone who'd made comment about this (though I am notorious for using the wrong search parameters).
Now, using jamieson630's information to FIND the audio track, actually inclodes your solution to the issue. Using the debugger (Ctrl+D)
Use the IMUSE section, specifically, the "imuse panic" command.
***This stops all audio tracks that are currently playing***
Then just walk into another area to load that area's sound as normal.
I do not know if the issue will occur again, but it's a good way to make it "STOP THAT!" (as I was yelling it repeatedly at my computer).

I have opened a pull request which should fix both (Booty and Scabb Island) of these issues.
It would be great if anyone (besides me) could confirm this indeed fixes it. You don't need fast mode to reproduce them, a short explanation of how to trigger it is in the code.

The PR got merged.
Saved game with described problem. Wander around a bit to see how the problem persists.
