Youtube audio is extremely slow, I reckon at 10%, but the video is fine and can be sped up or down. The problem persists even in troubleshooting mode, after cache clearing, hardware acceleration turned off, enabled DRM and widevine, driver updates, in private mode or not, logged in or not, firefox restarts, computer restarts. But Youtube plays fine in Chrome and Edge. I dont think I didnt anything drastically different, or updated win10 or firefox, or messed with anything. It was working fine a day ago. Is there any way to reset something?
