Remarks

Sets the specified output gain value on all channels of this track.

Gain values are clamped to the closed interval [0.0, max] where max is the value of #getMaxVolume. A value of 0.0 results in zero gain (silence), and a value of 1.0 means unity gain (signal unchanged). The default value is 1.0 meaning unity gain.

This API is preferred over #setStereoVolume, as it more gracefully scales down to mono, and up to multi-channel content beyond stereo.

The word "volume" in the API name is historical; this is actually a linear gain.
