Hello everyone!
I was sent a PDF of a flyer for training to test for 508 compliance - I have never encountered a PDF like this one before.
It does NOT pass the Adobe Acrobat accessibility checker as nothing is tagged, but the file is read by JAWS. The creator has also imbedded an audio button, "Click to activate," that shares an audio of the flyer content/information.
Does this PDF pass if all the information of the flyer is included in the audio, even though the actual PDF file is not compliant?
Thank you!

My guess is the audio is not accessible because it is not navigable. You start at the top and listen to the whole thing, without the ability to skip element to element. If there are links, sounds like they are not keyboard activated.

You're right, even the audio button I can not navigate to via the keyboard and I can not stop or pause the audio either.

Joe - What WCAG standard do you think this fails under?
I'm looking at " Guideline 2.2 â Enough Time; Provide users enough time to read and use content."
Under guideline "SL12: Pausing, Stopping, or Playing Media in Silverlight MediaElements"

I would think this fails WCAG (and PDF/UA 1) on several levels.
If a PDF is not tagged, it is not accessible.
Tags have to be the correct tag for the content and in a logical reading order.
While Adobe Reader and other PDF Viewers have the ability to try to render content to "trusted adaptive technology", this is different each time you open the same PDF. There is no way to tell if content is missing or in any logical order...that's what the tags do.
I created a book a few years ago with tutorial videos in it to demonstrate the inaccessibility of this type of content presentation. Multimedia does have to be added before the tags because annotations are created when multimedia is added correctly...although you could try to add multimedia to a tagged PDF using the "Find Unmarked Annotations" capability.
We see similar accessibility barriers when forms have form controls but no tags. It is the tags that connect everything and make the PDF usable (accessible).
The biggest problem is trying to find a way for keyboard navigation to the multimedia followed by an equally large problem of being able to use the player with the keyboard and/or adaptive technology within the PDF viewer.
This solution is similar to the wrong approach of having a scanned image of a document with either the Alt Text or the Actual Text attribute on each page. You can't navigate by heading, understand structure or quickly find what you want.
It is wrong on so many levels and for so many checkpoints in both WCAG and PDF/UA 1.
