Packs sound fading away when increasing thrust.

Like the title states I've observed that when increasing thrust the sound of the packs becomes much quiter, which shouldn't be the case. This is especially noticeable when taxiing.

Still not fixed in 1.0.6! Any estimation?

Not working in V1.0.6.

To compensate the fade away, I've tried it with APU and APU bleed on, even then, the sounds are fading away, that should not be the case, because APU bleed overides the engine packs.
