Black Death track, no planes sound

[FAE_Cazador]

Hi all, Am I the only one that cannot hear plane engine's sounds in The Black Death track, excepting Bf-109? I can hear:
- Explosions of ordenance
- Pilot's chat (a lot of chit chat, BTW)
- Machineguns & cannons sounds
- Break sounds when Bf110 collides and tears Hurricane's wing.
- Planes exploding when hitting ground.
- Bf-109 engine

But I cannot hear anything from Bf-110 and Hurricane engines, which is very annoying.

Of course selecting them as a pilot myself or to fly against them, I can hear them.

Very surprising!
