Wwise motion (vibrations) causes voice starvation on Switch

Question

We're experiencing an issue where enabling vibrations in the game on Switch causes audio stuttering (voice starvation). When the vibration strength/volume is set to zero, everything works fine.

Notes:

• All vibrations are handled through Wwise.

• CPU usage remains nearly the same whether vibrations are on or off.

• There seems to be enough CPU headroom for additional voices.

• The issue is Switch specific - other platforms work without problems.

• Wwise version - 2022.1.16, Unity version - 2022.3.46f1

Could it be an issue with how the vibrations are being triggered in the game engine?
