#5869 SCI - MT32 support in LSL3
The MT32 support in Sierra LSL3 has a bug which was present, but not visible in
version 1.2. Starting that game in 1.4 development release and in 1.3.1 gives the following
error messages and results in audible sound glitches - even in the intro sequence.
These gitches were already present in version 1.2 but didn't result in a error message.
I checked that the games files are not corrupted with my real MT32.
LSL3 - MT32
WARNING: Object 0001:21ae (name scoreSound, script 0) varnum doesn't match baseObj's: obj 14, base 13!
WARNING: Object 0001:21da (name theMusic, script 0) varnum doesn't match baseObj's: obj 14, base 13!
WARNING: Object 0001:2206 (name theSoundFX, script 0) varnum doesn't match baseObj's: obj 14, base 13!
Platform: Win XP 32 - SP3 German, English LSL3 game files, id lsl3
There was no MT32 support for LSL3 in ScummVM 1.2 at all - it has a different MT32.DLL driver file. Regarding the sound glitches you are talking about: do you hear incorrect instruments? Is there a sample recording/video file where the correct music is heard, to have a comparison?
Sorry, correction: I was referring to LSL2 in the previous post when I was talking about MT32.DLL.
These warnings you pasted don't seem directly related to the issue, though. What sound settings are you using in ScummVM? What kind of sound glitches are you experiencing?
Intro MT32 correct sound
Intro MT32 Emulator defective
To be sure about that point: Are you saying that the warnings above have nothing to do with the sound problems?
Well - to make things clearer enclosed you will find two recording, one from the real MT32 and one from the MT32 emulator integrated in Scumm (using ROMs from a real MT32). You can hear crackles and wrong instruments at second 14 and deep "whoo" sound at the end of that part. This is when "presents" appears on the screen.
I hope that the files and description help to show the problem..
Thanks for the recordings :)
Yes, the warnings above have nothing to do with the sound problems - these are script bugs (related to sound).
The glitches you are describing sound like bugs with the version of the munt emulator included in ScummVM, and will likely be fixed once a new version of munt (which sounds closer to the original) is included in ScummVM
Just checked Scumm ver. 1.4 and the sound bug is still present.
The music glitches have now been fixed with the latest version of munt (the MT-32 emulator included in ScummVM).
Please try the latest daily version.
Closing as fixed
