DOTT: Silence during timesurfing cutscene
|Reported by:||SF/wooshell||Owned by:||SF/jamieson630|
|Cc:||Game:||Day of the Tentacle|
In DOTT (english talkie version), in the first timetravel cutscene, all sound is missing from the moment Laverne is shown in her chron-o-john racing into the future, until Hoagies chron-o-john hits the ground in colonial times. Before and after that, all sound is perfect. This bug appeared first somewhere around the 0.4.1 release, and is existant until todays 0.5.0-pre cvs version. I was only able to reproduce it on my Sun on Solaris 8, but other (BE?) platforms might show that as well. It does NOT occur in the Win32 version, though.

I first noticed the bug with one of the cvs versions just before 0.4.1, but I dont know exactly when it was introduced.

Sorry for my unclear expression. 0.4.1 was the first version where I saw that bug, seems I just overlooked it with the previous versions.
The oldest version I tested until now, that allows to reproduce this bug, is ScummVM 0.3.0b from 06.Dec.2002 (from the SF d/l server), with the adlib midi driver. I also tested the win32 versions of that release date and could NOT reproduce the bug there (neither with -eadlib nor with -ewindows). I dont know how to checkout even older versions, but it seems this bug has always been there and gone unnoticed.

Not much I can do with this, since I only have LE systems (more like *one* system, the Win32 box), and of course it runs fine for me on there. Does someone with a BE system running ScummVM, and a copy of the English talkie DOTT, want to check this out?
When I have more time, I'll try to isolate the events going on during that period and check to see if I can spot anything that might cause an endian problem.

Not sure what exactly I am supposed to reproduce here (does "sound" refer to SFX or music or both in this context?), but at least on my (BE) PPC Mac the music plays just fine with both the CoreAudio and the QuickTime driver. Maybe I have to try with - eadlib?

Hmm, would this be a Solaris problem specifically, then?
wooshell, which platform are your DOTT data files from -- the Win32 version? I just want to be sure both you and Fingolfin are running the same data files on your respective BE systems, just in case a difference in the data files might cause this bug to show up or disappear.

It might well be a Solaris-only problem, but I wonder why I don't get similar effects in other cutscenes or within other games on scummvm. I would appreciate any hints for bug hunting on my system. I used an English Talkie version, but as I don't keep the exe files and the CD doesn't have any distinctive text on it, I can't tell where the data files are from. The md5sum of tentacle.001 is c5d451e659e0915ac02f5807de3a0bc0, if that's of any help. If there's a discrepancy, I could make the data file available to you or Fingolfin for diff'ing.

That md5sum matches the one I have for the MSDOS English CD Talkie version of DOTT. So the data I'm working with matches what you're working with.
One thing you can do is uncomment (enable) the #define IMUSE_DEBUG at the top of imuse_internal.h. Then, log the console output of ScummVM to a file, starting, for instance, just before the Chrono-John diamond shatters, and ending a few seconds after the first "falling closeup" where you're not getting any sound. (Is Laverne the first one? You mentioned that she's where the sound stops.)

I put the log on http://www.dreamforge.de/error.txt and hope it's sufficiently commented.. I can't read a single thing out of it :o)
When the "camera" switches from Bernard's CoJohn to Laverne's, the last music notes end (not abruptly, rather the normal fadeout) and then silence. Sound starts quite abruptly as soon as Hoagies CoJohn hits the ground, with the crash sound effect and somewhere in the middle of the tune, AFAICS exactly on the place where it should be at that moment. (just a few notes left to the end of that tune.)

This is a platform performance issue. Apparently with any kind of graphics scaler in use, the animation for the cutscene is running too slow on wooshell's machine. As a result, the music is reaching the end before the switch from Bernard to Laverne occurs, and that particular music is not set up to loop. So, the player shuts down, and since the tracks for all three shots are part of the same music resource, none of them play after that. This is normal and proper behavior.
The silence phenomenon will also happen on any other platform using -t200 to play the music at 200% its normal speed. Same idea: music ends before the animation does.

What do you mean, "appeared first somewhere around the 0.4.1 release" ? Does it happen in 0.4.1 or not? Note that 0.4.1 was developed on a branch based on 0.4.0, separate from the main trunk.
