Media Sound Wave not playing while player re-enter the sound area

I found that I can set bVirtualizeWhenSilent directly in the code. But even when I set bVirtualizeWhenSilent to true, sounds not come back when I re-enter the sound area.

I debug the code and find the only place using bVirtualizeWhenSilent is

if (WaveInstance->GetVolume() > KINDA_SMALL_NUMBER || (bVirtualizeWhenSilent && AudioDevice->VirtualSoundsEnabled()))
{
    WaveInstances.Add(WaveInstance);
}

And it seems AudioDevice->VirtualSoundsEnabled() always return false. Is there any way to make it true?

Btw, I’m using SpawnSoundAttached to play the media sound wave.

Thanks a lot.
