Question about the future of Sound Cues- are they planned to be deprecated at some point in UE5.x? And if so, is there any timeline for that, or mention of a reliable migration path or tool? I’m curious what the long-term plans are for them, especially as MetaSounds continue to get more attention.

Also, after switching to 5.4, I’m seeing bugs with attenuation—particularly with non-spatialized radius where RadiusStart/RadiusEnd seem to behave unexpectedly. It’s noticeable when moving in and out of the falloff zone/ or sound is attached to a listener(panning and propagation issue). Is this a known issue, and is it still being actively maintained, or should we expect the pipeline to shift entirely toward MetaSounds?

Appreciate any insight!

Hello there @bartoszpie!

The information available on the subject comes from the latest [migration article](https://dev.epicgames.com/documentation/en-us/unreal-engine/unreal-engine-5-migration-guide#deprecations-5). There is no fixed date for the move yet, but it’s bound to happen in one of the updates for UE5.

> #### **Deprecations**
> 
> **Audio Volumes** , **Sound Class Mix** , and **Sound Cues** will be deprecated by UE 5.0, with plans to remove them in a future release of UE5.
> 
> - Sound Cues will be superseded by **MetaSounds** , which will be available in UE 5.0.
> - Sound Class Mix will be superseded by the **Modulation** and **Submix** systems, which are now available.
> - Audio Volumes will be superseded by a new system currently in development, which will be available in UE 5.0.
> 
> Users are encouraged to move to the new versions of these systems as soon as possible.

As for the problems with attenuation, I found a related bug fix report that was tackled and resolved for 5.6, updating to that version could resolve your issue:

>
> Welcome to the Unreal Engine Issue and Bug Tracker. You can check the status of an issue and search for existing bugs. See latest bug fixes too.

Still, I would prioritize moving your pipeline to MetaSounds, whenever possible.
