Oops missed a word


The current intent is:


Individuals who use screen reading software can find it hard to understand
the speech output if there is other audio playing at the same time. This
difficulty is exacerbated when the screen reader's speech output is software
based (as most are today) and is controlled via the same volume control as
the sound. <add>Therefore, it is important that the user be able to turn off
the background sound.</add>

<add>Note: Having control of the volume includes being able to reduce its
volume completely. </add>

Do we need to include 


" control the audio volume (including 0) which is ... "          ?   


Kind of awkward but.  


I think maybe we don't need to because I've never seen anything that claimed
to have volume control that you can't set to zero.  I'm sure there is one
but I THINK we could just put this in HTM. 


Other people's thoughts?

A follow up to one of my comments on the Survey that was tabled.


I think the language of 1.4.2 needs an adjustment. Or it needs to be fixed
in the intent.


<current SC 1.4.2>or a mechanism is available to control audio volume which
...</current SC 1.4.2>

An example. Some authors might say the user has "control" if they can only
adjust the volume a bit... which would defeat the purpose of the SC and let
them have distracting background. Let's add to the Intent... "Control means
that the volume can be reduced to zero DB"
