Failed Creating Opus Decoder and Source Starvation Errors on Nintendo Switch

0 votes

I'm currently building for Nintendo Switch and have set all audio to OpusNX. When playing the build, we are getting dozens of "Failed creating Opus Decoder" errors and multiple Source Starvation errors, which are heavily impacting the sound in the game.

At present, we have tried:

  • Lowering the overall quality of all audio in the Conversion Settings
  • Setting the sounds to either variable or constant bitrate
  • Reducing frame size
  • Increasing the I/O memory size in the Wwise Initialization Settings in Unity
  • Clearing the cache of all WEM files and regenerating everything 

Our current conversion settings for all audio is:

Quality: 9

Mode: Constant Bitrate

Frame Size: 20ms

Regardless of the things we have tried, there are no fewer instances of these errors.
