Sound Mixes do not seem to work for Macs. In this particular case I used the Push Sound Mix blueprint node to affect the currently playing sound in the level.

This same project works fine on Windows/PC as the changes to the EQ settings by pushing a new sound mixes are audible.

One thing to note, there is a crackling sound on Macs upon pressing the key to push the sound mix.

Steps to Reproduce

1. Open attached project on a Mac.
2. Press PIE.
3. Press the 'P' key and listen for EQ settings to change.
4. Repeat.

Outcome The current sound playing is not affected by either sound mix, and a slight crackling sound is audible as if it attempted to kick in the EQ settings.

Expected The Sound Mix should be pushed to the current sound playing and alternate between the two sound mixes created upon each key press.
