Text alternative is not appropriate
The alternative text for media content MUST accurately convey the purpose or title of the content.
People who are blind cannot see images on a page. In order to give people who cannot see an image access to the information conveyed by the image, it must have a text alternative. The text alternative must describe the information or function represented by the image. Screen readers can then use the alternative text to convey that information to the screen reader user.
For media files - such as podcasts and videos - the alternative text must identify the purpose or title of the media content so screen reader users can decide if they want to play it. This is in addition to the requirement for alternatives for the media content itself such as transcripts, captions, and audio descriptions.
Fix this issue by ensuring that the alternative text provided for the media file accurately describes the purpose or title of the media content.
