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?

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
