I got this issue too.

That was my theme fault even if audioplayer worked fine with wordpress 2.9.

Please assure that wp_head and wp_footer are called, respectively, before and after the post code.

e.g.

– RIGHT –
wp_head(); […] the_content(‘More’); […] wp_footer();

– WRONG –
wp_head(); […] wp_footer(); […] the_content(‘More’);

(Calling wp_head and wp_footer before the post code is not so weird in “fluid” themes)

It worked for me.

Hope it helps, sorry for my english
