Jack is the default. You can use ALSA with the -A option.

It will try to start Jack in that case (this may be removed in
future releases). If you start Aeolus in a terminal it will
usually report if anything goes wrong.

Aeolus also accepts MIDI over Jack if you have that enabled.

Make sure you're running Jack and Aeolus in RT mode. In many cases
that's enough to avoid xruns, even on a standard kernel (but YMMV).
45% CPU is on the high side. On my six year old 2G P4 it Aeolus
rarely goes above 15%, and quite less on average.
You also get a too high CPU estimate from Jack/Qjackctl if not
running realtime.
