Steps to Reproduce

1) Create a Sound Cue
2) Add a Wave Player node and connect to to a Continuous Modulator node. Connect that to the Output
3) Set a Sound Wave on the Wave Player. Set it to Looping
4) Open the Details parameter on the Continuous Modulator node and expand the Pitch Modulation Params section. Set the parameter name to Pitch.
6) Open up a level blueprint
7) On BeginPlay, set up your Sound Cue to Spawn and set the Float parameter to 0.0. Add a delay and then set it to 1.0
8) PIE

Expected Result:
 The sound plays pitched down for 2 second and then plays at normal speed

Actual Result:
 The sound plays pitched down indefinately.
