Using Godot Engine 3.2.3.stable

When I play my project in the editor, everything sounds fine. But when I play it as an HTML5 export, the audio becomes terribly crackly. I’ve tried tweaking some settings, but I can’t seem to find how to fix it.
Something I’ve also noticed is that the audio busses don’t function the same way in HTML5 as they do for other platforms. I have two buttons that mute and unmute my audio busses, but this doesn’t work at all when the project is played in HTML5.
The music file is a 277kb .ogg file, so I’m assuming the file size isn’t the issue.

I’ve been unable to find any documentation on this. Is this a common issue?
Any way to fix it?

This is a known bug caused by regressions in web browsers: Stuttering Audio on Chrome/Chromium (HTML5, Threads) · Issue #43210 · godotengine/godot · GitHub

Unfortunately, upgrading to 3.3rc8 and enabling threads in the HTML5 export preset most likely won’t solve it for now: Crackling audio playback on Chrome with HTML5 threads export (AudioWorklet) · Issue #47487 · godotengine/godot · GitHub
