While working on techniques for Guideline 2, I didn't write any specific techniques for Checkpoint 2.6: If a technology allows for more than one audio track, allow the user to choose from among tracks. I am unsure of the intent of this checkpoint. It seems to me that it might be a special case of Checkpoint 2.2: If a technology allows for more than one continuous equivalent tracks (e.g., closed captions, auditory descriptions, video of sign language, etc.), allow the user to choose from among the tracks. It would be a special case if the various audio tracks were considered continuous equivalents, such as versions of the audio channel or audio description in different languages. In that case, I think we can remove the checkpoint and make reference to multiple versions of audio in 2.2. However, if we are referring in 2.6 to audio tracks that are not continuous equivalents, such as director's comments or a laugh track, then the ability to turn them on and off is a UI issue, not an access issue, as far as I can see. And again, if this is the case I don't think this is a necessary checkpoint. I thought I had raised this question in the past, but I can't find it in the issues list. I apologize if I am re-opening a settled issue. -Madeleine Madeleine Rothberg The CPB/WGBH National Center for Accessible Media madeleine_rothberg@wgbh.org
