No problem, Edgar. I think there is a lot of good information in this thread, I wonder if it is searchable in some way because it could help others. I really appreciate all the help and all the inputs are helping me learn more things.

So this part of the mystery is resolved, and your system seems to be in good shape. I have to apologize for adding to confusion and leading you on the wrong track, just remember I'm not familiar with AV Linux (have looked at it several times in the past 15 years but never regularly used it...) and this 2016 version is significantly different from previous ones in that it incorporates the kxstudio repos as a core part, which i didn't realize at first. I'm really sorry for that. As for your crossover filter network, I've never tried to do such a thig in software, so I have to pass that on to more knwledgable folks...
