However, add some declaration of a type attribute to the source tag, for example: <source src="/media/audio/m4a/9001_10000/9807.m4a" type= "audio/mp4;codecs=&quot;mp4a.40.2&quot;"/> and audio playback will break. This happens on <audio> enabled Safari builds, w32 and OSX. I'm finding this problem by following what is currently defined for <audio> and <source> usage, on the whatwg documentation site. I don't have a profound understanding of how WebKit interacts with QuickTime or other media_kits. thanks jp 128514 1 eric.carlson 2009-06-26 10:55:04 -0700 This was fixed by http://trac.webkit.org/changeset/43972.
