Karl Tomlinson 0a8a3cbddb Bug 1869043 pull mixed audio from AudioMixer instead of using a callback r=padenot
AudioCallbackDriver is the only client to benefit from a callback.

StartMixing() is now required if reusing the AudioMixer because getting the
mixed data after mixing no longer collapses the duration to zero.
