    Unfortunately this isn't working on 2021.1 or 2021.x. I'm using the Unity DevOps Cloud Build to build the WebGL binary.

    I've sometimes had luck with 2020.1 builds.

    For compression format I'm using gzip. I've tried with Decompression Fallback on and off and Data Caching on/off.

    Additionally for the .data.gz, .framework.js.gz files I've been setting their Content-Types to application/octet-stream and Content-Encoding to gzip.

    As for when I have Decompression fallback on, I've been setting the .unityweb files I've been setting their Content-Types to application/octet-stream and Content-Encoding to gzip.

    I've been using AWS CloudFront and an S3 bucket for hosting.

    Still, sound will not work. Any suggestions?

    Worse than that, any call to play a sound seems to halt the app. 2020.3.9f1

    I don't know why it says "Fixed in 2020.2", it isn't. Bug is still in all 2020.2 versions, and confirmed it's also in 2020.3

    However it DOES appear to be fixed in 2021.1, if you download the beta and use it to build, sound works fine.

    I thought I was losing my mind - I couldn't find any info anywhere online about audio not working on Unity WebGL. I was trying to load the audio half a dozen different ways, playing with audio and build settings... insane.

    I'm using 2020.2f1 and still audio not plays? This is ridiculous!

    2020.2 was released with this bug in it? That's not ok.
    WebGL is completely unusable in the latest Unity version with this bug.
