Audio Quality Issue on Mobile Build Only

Unity
1

Hello,

I have discovered an issue where a specific event sounds rough or distorted during playback. (The audio crackles.)

This issue does not occur in the Unity Editor and can only be reproduced on mobile builds. We have not yet been able to identify the cause and would appreciate any assistance in investigating the issue.

The attached video named “Rain Issue Mobile Profile” was recorded while running the game on a mobile device and connecting to it through Connect to Game using the device’s IP address.

We have also attached a video named “Rain Issue Desktop Profile”, which was recorded while running the project in the Unity Editor. The issue does not occur in the Editor environment.

Our current versions are:

  • Unity Version: 2022.3.62f3

  • FMOD Version: 2.02.25

As part of our investigation, we have already tried the following:

  • Reduced the

    audio asset length to 50 seconds

  • Changed the Buffer Size to 1024 and 2048

  • Disabled Streaming

  • Changed the Custom Encoding Setting to Vorbis and FADPCM

Any help or suggestions would be greatly appreciated.

Thank you.
