Steps to Reproduce

1) Open AudioQA in Editor
2) Locate the MSS_Test_BiquadFilter asset in the Content Browser and add it to the default level
3) Open the level Blueprint and add a Set Float Parameter node. Connect the Ambient Sound Actor in the level to the Target. 
4) Set In Name to: Cutoff Frequency
5) Set the Cutoff Frequency to 20000
6) PIE and validate it works
7) Stop PIE. Open the Project Settings.
8) Select Windows and change the Audio Mixer Sample Rate to 32000
9) PIE again

Expected Result:
 Sound plays at full volume

Actual Result:
 Is silent
