the aircraft sound at the start is still present: at engine off , no device activated...just sitting at the start of the mission there is a sound like something working....
Is the sound only present in the cockpit views? If so, it might be the cockpit electronics sound?
If possible, please post a recording of the sound that you hear.
can you suggest some aircraft to try that could have the canopy latch?
The "canopy latch" is a new sound introduced by NG-SE that plays whenever an aircraft's canopy starts or stops opening or closing. Every aircraft with an openable canopy has the canopy latch sound if NG-SE and NG-USM are both active.
! NG-USM 4.12 Gun Classes is present only in the manual installation file and not in the auto installation file....is this correct?
The installer has these classes in the "Classes-BAT" folder, and only activates them when BAT is detected.
This is because the installer checks which game version the player has by checking which mods folders exist. If it notices the #WAW3 folder, it decides that the game-type must be BAT, so it knows that the user has version 4.12.
But, it if detects no #WAW3 folder, and detects the #SAS folder, then it will know that the player is using SAS ModAct... but it won't know what version of SAS ModAct is being used, and thus it won't know what game version is being used either. So, it doesn't know that it's safe to install the 4.12 gun classes, and doesn't install them.
I suppose future versions of the installer will put the gun classes in a JSGME mod so that they can be enabled manually.
The external/flyby sounds seem much lower than the cockpit stereo. [...] whilst the cockpit engine was pretty loud I can hardly hear the external engine sound at all
In the "! Next Generation Sound Engine" folder and, in that folder, the file "NGSE.ini". In that file, the "stereoVolume" setting can be decreased to decrease the sound of the stereo-effect cockpit engine sounds. The default value is 0.15, and the minimum value that NG-SE will accept is 0.1.
After fiddling around with various volume options, I'm unable to reproduce this issue myself. If even a value of 0.1 doesn't lower the volume enough, I might consider reducing the minimum value of that setting to something like 0.05, as it seems that people with different systems or other audio setups might have different results with the stereo effect.
One of favourite aircraft is the Storch [...] With the NG sound the engine is terrible - like a sewing machine on steroids, especially on high revs, and nothing like the real aircraft [...]
Having just now listened to a different cockpit recording of a Fi 156 flight (the one posted had mainly wind sound, with an almost inaudible engine), I agree: the NG-USM sounds for the Fi 156 are not correct. I will change this in a future update.
