[linux-audio-user] External MIDI ports disappeared!

I'm having trouble getting my external MIDI ports to work again. They worked fine in the morning, and now they're gone. I found out that my MIDI ports were missing when I fired up Rosegarden and it couldn't connect to any output ports. I googled, read manual pages and FAQs, and searched through mailing list archives for nearly a day. Coming up with nothing that helped, I'm hoping that some kind person reading this could help me figure this out. Here are some details. My loaded sound and/or MIDI related modules are these: snd-seq-oss 27648 0 snd-seq-midi-event 4480 1 snd-seq-oss snd-seq 40336 4 snd-seq-oss,snd-seq-midi-event snd-pcm-oss 45992 0 snd-mixer-oss 16384 1 snd-pcm-oss snd-ens1371 18020 0 snd-rawmidi 17700 1 snd-ens1371 snd-seq-device 5640 2 snd-seq-oss,snd-rawmidi snd-ac97-codec 59616 1 snd-ens1371 snd-pcm 68616 3 snd-pcm-oss,snd-ens1371,snd-ac97-codec snd-timer 19204 2 snd-seq,snd-pcm snd-page-alloc 6408 1 snd-pcm gameport 2176 1 snd-ens1371 snd 38244 10 snd-seq-oss,snd-seq,snd-pcm-oss,\ snd-mixer-oss,snd-ens1371,snd-rawmidi,\ snd-seq-device,snd-ac97-codec,snd-pcm,\ snd-timer soundcore 6112 2 snd,bttv [I broke the "snd" module line above.] The /proc files that seem important are these: :::::::::::::: /proc/asound/version :::::::::::::: Advanced Linux Sound Architecture Driver Version 1.0.6a.

Better yet, how can I fix it? Thanks much.... -- Kevin
