No sound out via headphone jack

I am quite confused about your mentioning “and the Creatives did not detect and pair with the Vero”. How would you pair from the Creatives to the Vero? I assume the creatives are an audio sink, so you always would pair from the Vero to the creatives and not the otherway around.
When paring from the Vero try using with or without pin. Also if all of that fails you can try from command line using bluetoothctl.
