I use jackdbus here:

ps ax|grep jack
21055 ?        SLsl  27:45 /usr/bin/jackdbus auto

You use -ndefault. And default is the loopback. If jack use it, it is
normal the ALSA program will fail to use it. You must tell jack to use
you first real sound card with something like -nhw:1 and it should work.

Best,
