php - Changing HTTP Headers -


i'm having issue html5 audio track duration in chrome , safari browsers. (mobile too) firefox fine.

instead of showing track duration, it's showing "infinity:nan:nan" in it's place. odd issue track duration shown here

i using jquery plugin automatically creates fallback flash file of tracks standard html5 <audio> tags:

<audio controls preload="none" itemprop="audio"> <source src="http://my-site/path/to/tracks/mus/town_where_i_live_prev.mp3" /> </audio>

the music player plays tracks fine, won't show duration number correctly.

i wondering if has http headers? found this i'm hoping fix issue, think i'm doing wrong. mentions had change content type "application/octet-stream" , fixed problem him. when check site's headers see "text/html; charset=utf-8". don't see "audio/mpeg", again tracks play fine though without that. question think might fix me, , if how go adding/editing site's http header?

i have built site custom wordpres theme, tried adding following functions.php file change header:

add_action( 'send_headers', 'add_header_vary_useragent' ); function add_header_vary_useragent() {     header( 'vary: user-agent' ); }

and instead of vary: user-agent

i changed 'content-type: application/octet-stream'

and after doing that, if visit site, browser automatically downloads index file. safari won't open it, i'm pretty sure wrong.

i found this on @ wordpress area on modifying it, i'm unclear should doing it. know site built on wordpress, thinking doesn't have wp related, posted here instead.

any direction or suggestions extremely appreciated!
