Create accessibility tags for rich media

Question

I am not able to fully remediate a file that contains an audio file. I used the following steps:

1) PDF file without audio files was remediated and tags were created.

2) The audio file was then added to the document. There were no options to specify accessibility tags.

3) Run the accessibility report and it states that the sound file does not have accessibility tags

4) Attempt to open this in the Content Pane or Accessibility Pane and there are no options to create the accessibility tag. Tried various menus, right-click, control-click, etc.

Does anyone know how to create the accessibility tags for audio files that are added to a PDF and/or how to add the audio files so that they become tagged.

Hello,

i only found out that auto-tagging puts the audio file in an annotation tag, which should be the right tag for rich media (https://pdfa.org/resource/tagged-pdf-best-practice-guide-syntax/).

The annotation tag can provide an alt-text, which may be formally correct, but to archive full accessibilty, I think, a full text description of the audio is needed.
