Well, I spoke too soon. There appears to be an element of
unpredictability here -- and I have found a number of forum posts which
seem to repeat the same, with no resolutions. Occasionally, after boot
and controller fireup, if I do the rmmod/modprobe, it all works...but
not usually. This does not change if I run everything as root. So I am
now wondering about the hardware side. I found one item where jackd
0.119 had a -M parameter to permit different timing settings for MIDI
than for audio, but I don't find that echoed in more recent versions.
My two controller devices (Yamaha MO8 via direct USB, and UX16 USB/MIDI
adapter) don't show up in Jack MIDI at all, so I don't think that would
help.
I do wonder about an 'initialization' of the USB side, or 'explicit
hardware powerup', or something, but I really do not know where to
look. Absolutely nothing in journalctl -f when I try the connections
using qjackctl, and no errors in qjackctl, it says that the ALSA
patchbay was successfully changed. No USB errors in journalctl -b
either, and I have tried both motherboard and PCI USB ports.
J.E.B.
