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.

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