Ah, a couple of responses while running an errand! Here goes:
Francesco:
i run aeolus through jack. i attempted to run it through alsa, but was
told that aeolus could not connect to alsa. This happened when setting the
sample rate to both 44100 and 48000.
It turns out that stops is installed, though it is the version that came
with the distro. it just never occurred to me that stops and aeolus would
be installed as separate programs. Could it be that the newer compiled
version is butting heads with this?
David:
The architecture is 64bit. My apologies for not mentioning that. My
projects are not quite in order enough for me to upgrade to 18.04, though
it was my plan to do so in the next few weeks.
That's what i was thinking: The path to definitions is not clearly
defined. i've never learned the format for setting those paths. i've half
a head to uninstall stops and recompile the newer version to see if that
solves anything. Given the morning's plans, though, i'm a few hours away
from that....
Thank you, Francesco and David, for your responses.
