[WebGL] FMOD error spam in the console when playing an Audio Clip in a Timeline

WebGL

Aug 15, 2020

How to reproduce:
1. Open the user's attached "WebGLAudio2020-2.zip" project
2. Open the "SampleScene" Scene
3. Go to File -> Build Settings
4. Make sure Platform is set to WebGL
5. Press Build And Run
6. Inspect the console in the browser

Expected result: No error messages are spammed in the browser's console
Actual result: "FMOD returns error code 78 (FMOD_ERR_UNIMPLEMENTED) executing setMix" error message is getting spammed in the browser's console

Reproducible with: 2019.1.0a8, 2019.4.9f1, 2020.1.4f1, 2020.2.0a21
Not reproducible with: 2018.4.26f1, 2019.1.0a7

Note:
- In 2018.4.26f1 - 2019.1.0a7 the same message is getting spammed as info message, but not as an error message (which should be the correct behavior, since the console could be filtered and important error messages would be visible, while in 2019.4, 2020.1 and 2020.2 error messages are getting spammed and important error messages can be lost in all of that spam)

Resolution Note (fix version 2021.2):

Fixed in: 2021.2.0a7
Resolution Note (fix version 2020.3):

Fixed in: 2020.3.39f1

We are still looking forward to the 2020.3.X fix for this. I Hope it is released soon.

EDIT: in 2021.3.0f1, when browser window is minimized, or another browser tab is active, coming back to the tab with the game makes the audio work. Please help!

Still getting these errors in WEBGL builds from 2021.3.0f1 ( = 2021 LTS !!!) and audio won't play.
Getting the same errors from 2020.3.26f1 but audio plays there. So that means I have to continue my project with the old version instead of the newer LTS version??

Still "Planned for 2020.3.X" after a year and more later.. This bug implies you cannot touch both Timeline and even manually managed Playable Graph in WebGL game if it has an audio node. That sounds like a very serious bug to me. All the cutscenes must be mute! Or having to time the audio separately using Timeline Marker that fires audioSource.PlayOneShot or something.

(By the way, the audio sounds perfect like it works, just that there are error spam. If Unity take a a day or a week surely this could be fixed? Come on, please!!)
