[LAD] Fedora 25 x86_64; Pulseaudio removed; ALSA recording and playing from multiple sources - JACK?

People, For playing from multiple sources, ALSA plus the version of .asoundrc below has been rock-solid for a couple of years now: I now want to use things like "recordmydesktop" which work fine with the mic but they do not record sound from audio or video clips that are playing eg from YouTube or local mpv etc. So, yet again, I started to try and make sense of JACK because I was pretty sure that it could solve this problem - but I have found sound on linux has always been a major pain and messing around with configs and rebooting etc on my big workstation is tedious so I think I will try to get something working on my laptop to begin with. Hopefully some jack gurus will have some suggestions about how to do what I want to do? I presume it is possible?
