Add IAssetSystem::OpenPicker( IAssetType* type, IAssetPickerListener* pListener ) which opens our AssetPicker from tools addon CQAttributeEditor_SoundPicker ( used in Hammer and probs other shit ) uses the managed AssetPicker, this is way easier to use, doesn't show duplicate entries and shows all sound events not just base ones.
