[Bug 18662] New: Setting audioparam value while there is an automation curve will cancel that automation curve and set value immediately

https://www.w3.org/Bugs/Public/show_bug.cgi?id=18662

           Summary: Setting audioparam value while there is an automation
                    curve will cancel that automation curve and set value
                    immediately

Discussed during the group's teleconference on 22nd August 2012:
http://www.w3.org/2012/08/22-audio-minutes#item03

The group discussed the desired behaviour in the following scenario:

1) an AudioParam automation curve is set (via e.g linearRampToValueAtTime() or
exponentialRampToValueAtTime()) 
2) during the course of the automation curve, the value is set via
AudioParam.value

The question was whether 
1) the setting of that value should be ignored, or
2) the setting should be equivalent to cancelScheduledValues() (cancelling the
automation curve) and setting the value

We resolved towards option 2.
