MTROPOLIS: Video/Audio Glitches in Obsidian

[Agent-G245]

Some interactive parts of the game Obsidian cause either

• Sound effects to play twice
• UI Elements not working at all.
• Visual nodes to reset.

I have made a livestream where I encountered these issues, timestamped below. ​https://www.youtube.com/watch?v=jCEp0qpm2X8

Noted areas:

• Spider: Ore dropper button, Spider Realm (sound plays twice, video doesn't play despite having correct chemical inserted.) (00:53:24)
• Spider: TV in chemistry lab has non-working Stop button, so video can't be paused. (00:48:12)
• Bismuth: Crossover lever plays "Chip missing" warning after pulling it with crossover chip in place. This also overlaps with the correct speech (Double play) (01:59:27)
• Bismuth: Painting disappeared from frame and reverted to empty frame, including docent. This soft-locked me and I had to load a save. (02:12:20)
• Conductor: Human Control cutscene played after flipping switch a second time (02:35:30)

ScummVM version: 2.9.0
OS: Windows 10 22H2, build 19045.5371

Note: I could not locate my latest saves or the directory they were stored in.
