You need some sort of unique identifier for a sound card. With the RME
cards that was easy, as they have individual serial numbers, which I add
to the card's name: HDSPe_f1cd85, for example. I did this because in the
setups those cards are used in, it is absolutely mandatory to identify
the cards (probably multiple cards of the same model) correctly.

In the hw: argument you can use the card's name. As you only have one
'UA25', this should work: jackd -d alsa -dhw:UA25
