SCUMM: MI (Sega MegaCD) - audio pops at the end of every SBL sound effect

This happens with current Git HEAD, but AFAICS it's been this way for many years.

Whenever a sound effect is played in the SegaCD release of Monkey1, a "pop" sound can be heard at the end of it. It happens on all the systems I have tested.

I don't my game game resources have any problem, GAME.000 is the one in the detection tables, and GAME.001 even matches the BACKUP.001 that's included in the CD:

c13225cb1bbd3bc9fe578301696d8021  GAME.000
808f192970d39b0e9a7db0664b647372  GAME.001
808f192970d39b0e9a7db0664b647372  BACKUP.001

(The sound resources are *not* the Redbook audio CD tracks used for the background music.)

Running the original game with OpenEmu/GenesisPlusGX, I can confirm that the original game doesn't have this behavior.

Maybe there's something inaccurate in the way the SBL sound effects are handled for the SegaCD platform?

Ah, I forgot to give two quick examples

1. At the front of the SCUMM bar, open/close the door multiple times
2. Go in front of the Governor's Mansion. The dogs bark; it's easy to hear the sound effect pops every time

You can see it in sound.cpp, line 449 - 465. Apparently, it is just guesswork test code that was never finished.
