in my HTML5 audio markup, I have the following

<audio>
 <source src="/media/audio/ogg/9001_10000/9807.ogg"

codecs=vorbis"/>
 <source src="/media/audio/m4a/9001_10000/9807.m4a"/>
</audio>

but I'm unsure what the equivalent type attribute for an m4a file
should be. Can someone advise?

Does this help?:

normally, reading the docs does help :-) However, in my example, I have
previously tried the following,

<source src="/media/audio/m4a/9001_10000/9807.m4a" type= "audio/mp4;
codecs=&quot;mp4a.40.2&quot;"/>

Using this, Safari stops playing the audio. It works without any type
attribute, but that feels wrong. I'm wondering if my attempts so far
have been using an incorrect mime-type, or/and a wrong codec
declaration.

I'm wondering if this has something to do with the issue,

Not dealing with parameters on a type attribute at all was fixed last August, see https://bugs.webkit.org/show_bug.cgi?id=20360.

The issue you are seeing here is caused by a problem with WebKit's interaction with QuickTime on the Mac. Can you please file a bug report on <https://bugs.webkit.org/> ?

  Thanks for pointing out the issue,

eric
