Subject: [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.
Compiled on Sep 30 2004 for kernel 2.6.7-1.mm.7mdk-i686-up-4GB.

::::::::::::::
/proc/asound/cards
::::::::::::::
0 [AudioPCI ]: ENS1371 - Ensoniq AudioPCI
                     Ensoniq AudioPCI ENS1371 at 0xdc00, irq 18

::::::::::::::
/proc/asound/devices
::::::::::::::
  0: [0- 0]: ctl
  8: [0- 0]: raw midi
 17: [0- 1]: digital audio playback
 16: [0- 0]: digital audio playback
 24: [0- 0]: digital audio capture
  1: : sequencer
 33: : timer

::::::::::::::
/proc/asound/card0/midi0
::::::::::::::
ES1371

Output 0
  Tx bytes : 0
Input 0
  Rx bytes : 0

I try to find ports like so:

[#43] aplaymidi -l
 Port Client name Port name

[#48] aconnect -li
client 0: 'System' [type=kernel]
    0 'Timer '
    1 'Announce '
        Connecting To: 63:0

[#49] aconnect -lo
[#50]

 

What can I do better to debug this? Better yet, how can I fix it?

Thanks much....
