Type errors when using Ref<number> for volume

[chuckntaylor]

I'm likely doing something wrong, or it is an unrelated IDE issue. I am getting an error: Type Ref<number> is not assignable to type '(MaybeRef<number> & number) | undefined when I do the following:

const systemSoundVolume = ref(0.5)
const notification = useSound('url-to-asset', {
volume: systemSoundVolume // error here
})

Any ideas?

For additional context, I manage all the app audio in an audioStore using pinia. So, this is not in the setup function of a component.
