Bad news:
https://developer.mozilla.org/en-US/docs/Media_formats_supported_by_the_audio_and_video_elements#MPEG_H.264_%28AAC_or_MP3%29

All free browsers drop support for MP3 because of licensing issues! That is the reason why the tag in Chrome and Firefox does not play MP3 natively.

For jPlayer, a fallback is to use the Flash Media Player in case MP3 is not supported, the issue with the flash player seems to be that only CBR with fixed frequencies are supported: http://www.jplayer.org/latest/developer-guide/#jPlayer-media-encoding

In Firefox 15 the demo file is stuttering :( In Chrome it works!
