zbPlayer is a very easy audio plugin – you can select some options like: include Download link or no, enable autoplay or no and setup width of player. Other things will be done by zbPlayer plugun automatically. One nice feature – player support cyrillic filenames without problem.
<h3>Known Issues</h3>
<h4>Sometime my .m4a fields doesn’t play. Why is it?</h4>
Unfortunately, some of .m4a files has nuances and cannot play by player. We can’t fix that. Use .mp3 files – they works always.

zbPlayer

zbPlayer is a small and very easy plugin. It does one thing: capture mp3 links and insert a small flash player instead.
