Audio position doesn't keep up with physics movement

Audio

Priority: 2Necessary for shipping a final release

-

Severity: 2No workaround

An audio source that moves as part of setup in physics does not update correctly, and ends up trailing behind the position of the audio listener.

Reproduction steps:
1. Open the attached project
2. Run the scene Scene_UpdateMovement
3. Observe the audio volume remains constant as the 'player' is moved in Update
4. Repeat in the scenes Scene_FixedUpdateMovement and/or Scene_PhysicsMovement
5. Observe that the audio gets quieter as the player moves faster and faster. Selecting the audio source show the Listener in the graph view as drifting further and further away, but the Transform in the scene always stays the same distance

Expected result:
High speed physics movement shouldn't cause the audio listener to think it's getting further away.

Reproducible in versions 5.3.7f1 (c347874230fb), 5.4.2p4 (e59bdccd995f), 5.5.0b11 (03364468e96e), in-Editor and in-build.

    Same in 5.5.0f2 it seems - It's killing my racing game...
