Firefox & Widevine -> Choppy audio (Works fine on Chrome)

[ameeno]

Hiya.

This extension makes audio very choppy on widevine DRM videos, for example, Udemy.

However, on chrome with the same addon, it works fine. This is a real shame as I prefer ff to chrome, and due to the choppiness, I need to use chrome instead of ff for DRM video watching.

Any fixes or patches?
