If you’re getting [WEBM](http://www.webmproject.org/) audio files instead of MP4 from YouTube or any other site. (webm can only be played in a browser) , disable your browser’s WEBM audio support, then YouTube or media site will send the audio in MPEG4 format.

- Type “about:config” in the address bar
- press `Enter` , click through any warning message and search for “webm”.
- Find and double-click `media.mediasource.webm.audio.enabled`.
- Its value will change to `false` and you’re set.
