Which audio adapter do you use to use a 2ndary sound card in jack?
1.jacl_load audioadapter
2. alsa_[in | out] ?
3. zita_[a2j | j2a] ?

I am not sure the state of audioadapter in jackd v2. When I need I use zita_a2j, it is superior to alsa_in/out. Jackd v1 incorporated the equivalent of the zita adapters into an internal client. Doing the same for jackd v2 was on the list of development tasks a couple of years ago, but I do not know the current status.

why do you use the one you use? What are its advantages ? Have you identified or do you know of any disadvantages for each of the above ?

The problems in alsa_in/out and the solution in zita_a2j/j2a are described in the paper authored by Fons:
