MetaSound audio preview in animation window

Hi all,

I am lining up a few sounds on a notify track on an animation. For some reason I get audio preview when using the sound file as source, but when I use a metasound source I don’t hear any preview, either when scrubbing or simple playback.

I have checked that the sound is playing in metasound source file, it is a fairly simple setup, mono output, random float on pitch, screenshot atttaced.

Any ideas? Is there a setting to turn off/on audio preview for metasound sources in an animation notify track?

Best wishes,
