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.

I try to find ports like so:

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....

Are you using FC3 by any chance?

Your problem is a little different it seems....did you change or alter
anything in the time between midi ports showing and midi ports not
showing? It seems the right modules are still loaded according to your
lsmod...

Hmm. No kernel changes here. The kernel I'm using is my default
one in LILO, and I seldom boot anything other.

Yes. I turned off the on-board sound. I did that in order to
get the ENS1317 to be recognized at boot-time. I couldn't get
modules.conf to get those modules loaded. I'm 94.81% positive
that MIDI worked after that change. But, I turned the on-board
sound back on anyway. No change in MIDI behavior. On-board
sound is back off now for ease of loading the ENS1317 modules at
boot-time.
I'm using a different monitor and a different PS/2 mouse than I
was when MIDI worked. It could be that MIDI was broken before
making these changes; I can't remember. But, I do know that MIDI
hasn't worked ever since changing the monitor and mouse. The
mouse is using the same exact driver as before. The monitor
changed resolution capability. The video card is exactly the
same, as is the video card driver. I could put it back the way
it was, but it would be truly surprising to me if that had any
effect. Your thoughts?

Now if you were 94.825 % sure I'd could prolly help...but since your
only 94.81%... 8~) (Sorry...couldn't resist)
I'd do some Googling on Udev. Lee cites this in a folowing post and
although I'm a MDK user, I'm not familiar with Udev at all. It's a new
thingy. And I think 10.1 is the first release to use it in MDK?
Try looking at your modprobe.conf and seeing if there is anything funky
going on there as a result of turning off your card the first time;
"hard drake" can do some odd things at times in detecting new
hardware...or what it perceives as new.

I try not to think and it works for me! Having not thought about
that...let me not think about this; I doubt your mouse or monitor had
bumpkiss to do with anything here but I can only be 94.81% sure about
that. (eh-hem)

I did this in the BIOS. My ENS1317 is a PCI card.

Whew! Someone caught my joke. -sigh-of-relief-

Just checked the Mandrakelinux website, and yes udev is first seen in
10.1.

Well, if harddrake can mess up udev, then maybe that could be part of
the snarl too?
I'll follow your leads. Thanks!

The only think I can think of is that it might be udev related.

udev? Is that like DevFs? I think my system runs DevFs.
Thx again...

Looking at the lsmod output from my original email in this thread
I see that the snd-seq-midi module was *NOT* loaded. If I want
to have it be reliable, then I apparently should upgrade to ALSA
1.0.7. Is there a preferred method of upgrading ALSA on Mandrake
10.1? The last time I tried to upgrade ALSA (from 0.5 to 0.9)
on Mandrake (was it 9.0?) the drivers were built as part of the
kernel, and the ALSA apps were built & packaged separately. I'm
OK with building kernels and such. But, I'd like a *preferred*
recipe, if anyone has something like that.
Thanks...
P.S.: FWIW, I'll use my MandrakeClub status to request that they
release ALSA 1.0.7 as an upgrade.

I took the extreme route to solve my problem: I reinstalled my
system. I know, I know, this is not WinXX -- What? Was I thinking?
Since I only installed the system 3-4 days earlier, I didn't have
that much to lose.
At any rate, MIDI ports are back now, and duplex sound works. I
haven't looked at everything, but all I checked out before works
again.
Cheers....

For what it's worth, using these kernels on Mandrake 10.1 has these
results for me:
kernel-2.6.8.1.12mdk-1-1mdk - ALSA modules load fine and system
power-off works too.
kernel-multimedia-i686-up-4GB-2.6.7-1.mm.3mdk - ALSA modules load
fine. System won't power-off at shutdown (requires operator to press
on/off switch).
kernel-multimedia-i686-up-4GB-2.6.7-1.mm.7mdk - ALSA module loading
leaves snd-seq-midi *unloaded*, requires modprobe to load it. System
won't power-off at shutdown.
I hope that helps someone. Cheers....
