SU8 Beta - Sound volume bug

[MSFS 2020] Questions & Community Discussions Sound

Hi! There’s a problem with legacy sounds that is reproducible in SU8 beta only
(I have both versions installed and checked it’s SU8 only). In my EGAR Rothera
scenery (see Marketplace) most simobjects on the ground have legacy sounds
attached. Since SU8 all of them are audible at almost full volume once the
simobjects are loaded - but only when inside the cockpit. Developer camera
and spotplane view are fine. Here’s an example:

When removing the “viewpoint=1” (=cockpit) entries, the problem is gone:

Of course it would be preferable if the bug would be removed in MSFS itself
instead of having to push out yet another fix. It surely wasn’t intentional
that outside sounds play louder inside the cockpit than outside. :slight_smile: Plus it
would be nice to still being able to hear a few sounds inside the cockpit at
normal volume as was the case before.

Hello @Sasa Actually, this is the result of a bug fix where the legacy sounds
were never played in cockpit view. Now they’re played but you seem to be
right and there is an issue with sound not being attenuated over distance.
Developers are looking at it. The time for us to identify and fix it, I doubt
it’ll make it into SU8 final build. SU9 is the realistic target. This is also
why we strongly encourage using Wwise. We barely have any content using the
legacy workflow and it’s way more prone to bugs and errors from our part.
Thank you for reporting the problem and our apologies for the inconvenience
it’s causing Regards, Sylvain

Thank you, Sylvain! That’s indeed a funny bug - I didn’t even notice! :slight_smile: Will
deactivate the “viewpoint=1” sounds for now and see how soon I can get my
first Wwise sounds running.
