RE: Question about SC 1.4.2 - can this be met by relying on Windows (or otherwise the platform or user agent) to do it for you?

Right you are James, 

 

It’s down an extra layer in the mixer, so this volume would have to be off before the person starts surfing. No way to get to it with music playing.

 

It is not so much an authoring technique, it is a user technique, and we generally don’t get into telling folks how to use their own technology, although we have a few examples in the techniques, of user agent notes with JAWS commands...

 

But I think we need a bright line between Authoring techniques for our “Authoring Guidelines” and strategies for users... the latter is not an authoring technique which is our mandate.

On my version of windows 7 I can reduce the volume of Firefox/ie without reducing my jaws volume.

I just checked this... it turns off the Screen Reader also, so no I would say not.

 

The whole point is so the screen reader can be hear without music drowning it out.

Would it not be sufficient to be in an environment where one has access to, but is not limited to windows 7? We have considered techniques that have support only in certain browsers, especially the infamous "headers technique" relying on a plugin. With regard to web technology I believe we have said in the meetings that support for a certain technique does not have to be across the board. Is an operating system different in this regard?

Yes that would be a technique if you are in an environment that guarantees that only Windows 7 (or whatever versions) are used by people viewing the web page.   Not sure how you would enforce that.  Otherwise it would not work.

 

  So we couldn’t list it as a sufficient tech I wouldn’t think.

Colleagues,

I was recently reminded that Windows 7 (and perhaps earlier) has a nice feature in the "Volume Mixer" panel, which provides support for independent, per-application setting of the volume level (including per-application muting).  This specifically allows me to turn down or off the volume of all audio coming from my web user agent.

Would you agree that this would be "a mechanism [that] is available to control audio volume independently from the overall system volume level", such that web pages/apps running on Windows 7 could automatically meet SC 1.4.2 Audio Control?

If so, is this perhaps a potential new success technique for us?  Something like "Running on a platform or user agent that allows the volume level to be adjusted or muted either by the user agent or on a per-application basis"?


On the other hand...  would doing this effectively prevent the use of cloud-based AT?  If I'm not mistaken, we typically haven't done a lot in our techniques that contemplates web-delivered/cloud-based AT...

Peter
