Hello,
Just updated with the latest hot fix and although it says that there were fixes to the sound engine, I have actually lost some of the sounds I had before.
1. The only switches that make sounds when they are switched are fuel tanks and landing lights... All other switches have no sounds. i.e. anti ice/pitot/external lights/autobrake etc. (I have seen videos of other people that had sounds turning on the anti ice and pitot heat for example.. I don't have that).
2. Engine startup. I had pretty fantastic engine startup sounds in 1.0.3 but with the latest update the engine sounds only really kick in once the engine is in idle after start up.
3. Engine spool up. Engine spool up sound does not seem to be working as it was very well before the update. On take off for example, the initial spool up is heard, but then the engines are almost silent until they hit the takeoff setting at which case there is that loud roaring/ringing sound.
Hope that is helpful!.
Cheers,
Zain
