Audio Controls Request

[sylistine]

Would love to see the ability to adjust volume and scrub audio.

I sometimes want to tune my shader to emphasize a specific section of the sound texture, but often have to wait minutes for the song to loop. Scrubbing would help here. Additionally, I might not want to have the song at full volume while editing. A window can be muted via chrome, but a simple volume bar in the page itself would be convenient.
