Setting the Audio Mixer Sample Rate to 32000kHz causes underrun spam in audio bus reader and writer nodes and sounds to playback jittery. Tested with 24kHz and 32kHz.
Does not repro in //Fortnite/Release-26.00 CL27996871
LogMetaSound: Warning: Underrun detected in audio bus reader node. LogMetaSound: Warning: Underrun detected in audio bus reader node. LogMetaSound: Warning: Underrun detected in audio bus reader node. LogMetaSound: Warning: Underrun detected in audio bus writer node.
1) Launch AudioQA
2) Open the Project Settings
3) Unser Platforms, select your platform (ex Windows)
4) Set the Audio Mixer Sample Rate to 32000 or set the Sample Rate using the MetaSound Platform Quality Settings
5) Restart the Editor
6) In the Content Browser, go to Assets > MetaSounds > AudioBus
7) Click the thumbnail to preview any of the MetaSounds in that folder
Expected Result:
The assets play without issue (note: not all of them will generate audio, but there should be no warnings/errors)
Actual Result:
Warnings spam the logs. The MetaSounds that do play sound are jittery.
