Playback speed >2x sound is garbled for HTML5 Audio/Video
When using playback speed greater than 2x, the sound is garbled for HTML5 Audio/Video. I have tried the same site in Chrome and Edge and the audio sounds fine when playing at 3x.
On sites that do not natively allow speed control, I use the Video Speed Controller plugin to change the speed. With and without the plugin, playing faster than 2x speed causes the audio to be garbled and not just faster.
I want to switch to firefox fulltime, but until this issue is resolved I will be unable to.
Thanks for your help.

Hello,
The Refresh feature (called "Reset" in older Firefox versions) can fix many issues by restoring Firefox to its factory default state while saving your bookmarks, history, passwords, cookies, and other essential information.
Note: When you use this feature, you will lose any extensions, toolbar customizations, and some preferences. See the Refresh Firefox - reset add-ons and settings article for more information.
To Refresh Firefox:
- Open the Troubleshooting Information page using one of these methods:
- Click the menu button
, click help 
and select Troubleshooting Information. A new tab containing your troubleshooting information should open.
- If you're unable to access the Help menu, type about:support in your address bar to bring up the Troubleshooting Information page.
- Click the menu button
- At the top right corner of the page, you should see a button that says "Refresh Firefox" ("Reset Firefox" in older Firefox versions). Click on it.
- Firefox will close. After the refresh process is completed, Firefox will show a window with the information that is imported.
- Click Finish and Firefox will reopen.

Hello,
Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache. Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:
- Click the menu button , choose History, and then "Clear Recent History...".
- Under "Time range to clear", select "Everything".
- Now, click the arrow next to Details to toggle the Details list active.
- From the details list, check Cache and Cookies and uncheck everything else.
- Now click the "Clear Now" button.
Further information can be found in the Delete browsing, search and download history on Firefox article.
