uLipSync 3.0.2 not working with WebGL in Unity 2022.3

[horeatrinca]

Hi! I'm trying to use the plugin in a WebGL build, but the lips are not moving.

Test procedure:

1. Start a brand new project, install the 3.0.2 unity package.
2. Comment out anything microphone related, so the build can succeed.
3. Do a WebGL build of the scene called 01-1. Play Audio Clip

Result: Lips are not moving. No errors are shown in the browser console, apart from a warning:

An AudioContext was prevented from starting automatically. It must be created or resumed after a user gesture on the page

Tested on the latest Firefox and Chrome browsers (Windows 10).

Notes:

• Lips are moving correctly in the editor and Windows standalone builds
• I've read the internet high and low and it looks like the job system should be supported, it's just that the job count is set to 0 so that everything runs on the main thread
• I tried setting max job count to 0 in the unity editor to see if that makes any difference, but the editor works well with that setting as well. I did it by setting JobsUtility.JobWorkerCount = 0; in uLipSync.cs's awake method.

Has anyone solved this issue?
