Possible issue with `AudioParam#cancelAndHoldAtTime`

[b-ma]

Hey,

Not really sure of what is happening with this method, but it doesn't sound right. E.g. when simply doing

env.gain.cancelAndHoldAtTime(now);
env.gain.linearRampToValueAtTime(0, now + releaseDuration);

we can ear a strange drop rather than a clean fade out, sounds like the linear ramp doesn't start from the right value.

I will have a closer look as soon as possible (... and happy new year :)

Hum... may be a misunderstanding on my side, I need to re-dig into the spec and compare with browser's behaviour
