Checking duration on Sound types always returns 0

[adbalano]

It appears checking duration on a Sound always returns 0.

this.tracks.push(await this.assets.createSound( 'Track1', { uri:${this.baseUrl}/RadioTuningshort.wav` }
));

    console.log( "Duration " + this.tracks[0].duration );`

this.tracks - an array of type Sound
this.assets - an Asset Container
RadioTuningshort.wav is a 4 second clip of radio static.

Per Steven V. I have tried to make sure the Sound was created.
