Hello Ian,

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,
