Error is thrown when playing audio through Timeline with the "Disable Unity Audio" setting on

-

Jul 17, 2025

How to reproduce:
1. Open the “timeline-audio-bug.zip“ project
2. Build and run the project for the Windows Dedicated Server platform
3. Observe the Console

Expected result: Nothing is output
Actual result: “AudioPlayableOutput::OnApplyFMOD: Could not get FMOD System.“ error is output

Reproducible in: 6000.0.0b14 (a038ffb60cdd), 6000.0.54f1, 6000.1.12f1, 6000.2.0b10, 6000.3.0a2
Not reproducible in: 6000.0.0b13

Reproduced on: Windows 11 Pro (24H2)
Not reproduced on: No other environment tested

Notes:

- The reporter states that playing audio through the script does not reproduce the bug

- This is reproduced on any standalone player when audio is manually disabled in the project settings. The reason for this appearing in the dedicated server is because it automatically disables audio
