Aircraft compatibility FS20: Why engine sounds in the VC view are inaudible?

Hi,

We have develop a Wwise package (via an external studio) for an aircraft, whic is perfect under MSFS2020.
Using this aircraft in compatibility under MSFS2024, the engine sounds are inaudibles when the vue is located in the VC while they work perfectly when the user is in external view.

Does this has some reason related to the version of Wwise program used to compile the package: Wwise v2019 versus Wwise 2020 ?

If this were checked, all the previously developed sound packages would have to be redone.?

make sure your not using Headphone simulation
The noise cancelling is pretty extreme LOL

Thank you for your advice but even at 68 years I can still hear my subwoofer and two speakers and make the difference with an audio caque.
It seemed to me that we were talking between developers, so serious people who know how to do a test, list the conditions of this test and transmit an error report.

What’s more, there are not 36 studios doing this kind of work on Wwise packages in our environment and they have assured me that it was a MSFS bug. As no one has yet spoken of it, I have taken the liberty of asking the question openly.

Perhaps related to this?

The phenomenon occurs as soon as after entering SHIFT+C you switch in the cockpit and start the engine, no sound is heard (I removed my earplugs :innocent:).
If the toolbar camera menu is used to view the exterior of the aircraft, the sound of the engine become normal to what was in the original position.
We change again in the VC and the sound becomes inaudible.
We can repeat this several times it is reproducible.

The version used is DEV alpha 1.0.88.0

PS: With aircraft build with Legacy sounds (wav files) no problem occurs.

Woahh man … just trying to be helpful with a suggestion
No need for your sarcastic shoot down

PS. I think I am 65 and a Serious person with 30 + YEARS in Flightsim development … Just so ya know :slight_smile:

Clearly misunderstanding happened here. @NightMercury358 proposed to turn off Headphones option in MSFS settings, which was useful advice as it blocks many sounds indeed.

If I misunderstood you, please excuse me NightMercury358 but the sound levels and their options are in the state that the Microsoft installation has realized: nothing has been changed and all sliders are on 100%

An aircraft with legacy sounds does not have this kind of problem, testing in the same conditions

I understand your advice but if it was one explication it should be the same effects with the two aircrafts? No ?

@LagaffeVFR5476
Still no need for you to jump on me

Given my misunderstanding of your first answer I have just apologized
Then I just gave additional information on the problem : it’s all.
I do not jump on anyone and I modify may answer to avoid misfit: I cannot do more.

You may need to switch from using “switches” and instead use the camera state to control internal/external levels. Remove the internal combustion effects from the “combustion” switch, and instead add a viewpoint state (see photo).

You will need to change your events to play both internal/external sounds separately.

I have not used internal switches in a while, as I could never get them to work properly.

Also: you may need to migrate your project from FS20’s build to FS24’s wwise build. See the SDK documentation here: Audio Migration And Updating

Thanks Tyler for your answer, I will see as soon as possible in the day.
