Bug description: Changing cameras is stopping some of the sounds from playing. We don’t recall this issue before 1.0.84.0 and does not happen on FS20 with the exact same soundpack.
We launch the aircraft on the ramp, start the battery (which has an associated “avionics sound”), change camera to external, and hop back into internal - and the sound is gone.
This seems to affect a handful of other “internal only” sounds (Alarms, GPWS Calls, etc).
The package is non-modular. Have tried various aircraft, all presenting the same issue.
Troop Jump alarm - load the aircraft C&D (Bilbao helicopter parking works best, only airport I’ve seen with heli parking), get in the cockpit by ctrl C, turn on Battery, set turn on alam, switch cameras.
This is a 100% repro rate in your case?
I’ve followed your repro steps but so far, I always have the troop jump alarm, regardless of the camera I switch to, when I go back to the cockpit.
I can also always here the battery related background noise.
It’s 100% repro on my end, and everyone on the team is experiencing the same. I can attach a video if required. Keep in mind I’m not sideloading the CH47, but instead I have a FS24 build that I can also provide.
C17, its pretty evident with the Stall or Fire tests:
Start either C&D or ready to fly, set either of these test, change cameras and sounds are gone. Its consistently replicable on my system and at least 3 other sim installs.
I thought this was a backward compatibility issue and tested the 2020 package on 2024.
I checked the 2024 version and was able to replicate the problem. This is being investigated by the sound team.
Are these sounds positioned via node names by any chance? We suspect this has to do with the LOD selection and wwise losing the sound position when a node is unloaded/reloaded.
If so, positioning these sounds via XYZ positions rather than node names should be a good workaround.
Glad you were able to confirm. It does seem that all the missing sounds are indeed positioned via node names, so your explanation does make sense.
However, it is far too late for us to modify the entire soundpack for the main aircraft affected, which is a 1st party aircraft going live tomorrow. We can’t push it through QA this fast, and it is quite a risky endeavour repositioning all these sounds…
Node placement of sounds is also widely used across many aircraft, so beware this affects many others out there.
This is not needed in your case, and can cause this bug.
In the case of the CH47 troop alarm, the sound was not looping at all which can also be caused by an incorrect configuration on Wwise side
Ideally, if you can’t share a package with the Wwise project, creating a demo Wwise project with a dummy sound that replicates the problem could help us a lot.
Thank you.
This allowed us to confirm this is caused by sounds using node names for position, being incorrectly positioned after a model/LOD switch.
Position falls back to aircraft datum, and combined with attenuation, this explains why some sounds can still be heard but are quieter.
I’ll update this post as soon as we have a fix in the pipes.
