I was looking for something else and then stumbled into @Its_capt_j’s post about South Park. Even though I have the Video Doorbell v2 
that uses the house’s built-in mechanical chime (plus Cam Pan v3s and Cam OGs as accessory chimes), I think it’d be fun to be able to change the sound that Video Doorbell v2 itself makes wherever it’s mounted (through its speaker). I imagine that could provide for some interesting event captures when an unexpected sound surprises a button pusher on my porch. This gets my Vote.
