/dev/sequencer does not exist --- Found a fix for this !!!!!

Hi guys i used to be able to play midi files and load sf2 into my audigy 2 platinum card. But last week i upgraded my system which was a 2.4 kernel and since then i get /dev/sequencer no such device.
I bit the bullet and upgraded to the 2.6-scsi kernel.
Got my sound working under alsa but still if i use sfxload i get /dev/sequencer no such device.
Now i know its there in /dev/sequencer becuase i checked the links etc.

Also here is my lsmod output :

Re: /dev/sequencer does not exist --- Found a fix for this !!!!!

Hi, try

modprobe snd-seq

or add snd-seq to your modules array in rc.conf... that works nicely for me... also try this: wiki.archlinux.org/index.php/SB_Live%21_Midi

Re: /dev/sequencer does not exist --- Found a fix for this !!!!!

It worked initially until i added snd-seq to my rc.conf and rebooted.
No i still get no such device again....

I even removed snd-seq from rc.conf rebooted and tryed modprobe but still nothing.
Why the hell did it work that once here is my updated lsmod :

Re: /dev/sequencer does not exist --- Found a fix for this !!!!!

Are these in the right order or is something missing.

# Module to load at boot-up (in this order)
#   (prefix a module with a ! to disable it)

MODULES=(usb-storage ide-floppy ide-scsi 3c59x snd-emu10k1 snd-pcm-oss snd-mixer-oss snd-seq-oss lp parport ohci1394 videodev)

Re: /dev/sequencer does not exist --- Found a fix for this !!!!!

Hmmm, well snd-seq is my last one in the array (I also have sb live):

MODULES=(uhci-hcd ehci-hcd via-rhine snd-emu10k1 snd-seq)

Hmm, maybe those oss-compatibility ones are messing something up?

Re: /dev/sequencer does not exist --- Found a fix for this !!!!!

try modprobe  snd-seq-oss
instead of modprobe  snd-seq

EDIT: You can try modprobing the modules in /lib/modules/2.6.12-ARCH/kernel/sound/core/seq
One of them might do the trick.

Re: /dev/sequencer does not exist --- Found a fix for this !!!!!

well, looking at your lsmod output, and comparing that to your very short MODULES entry, i'd say you're using hotplug.

if hotplug is loading modules for your soundcard, it's happening after the MODULES list is loaded.

i've never liked hotplug, so what you can do is add all the modules from lsmod to your MODULES list. by the way, lsmod puts the last loaded modules on the top of the list, so you're going to want to reverse it.

Re: /dev/sequencer does not exist --- Found a fix for this !!!!!

Just looking at my kernel logs and i found this.

Aug  5 18:28:22 justin kernel: Inspecting /boot/System.map
Aug  5 18:28:22 justin kernel: Symbol table has incorrect version number.
Aug  5 18:28:22 justin kernel: Cannot find map file.
Aug  5 18:28:22 justin kernel: No module symbols loaded - kernel modules not enabled.

Could that be the root of my problem ???

Help please i need my midi back...

Re: /dev/sequencer does not exist --- Found a fix for this !!!!!

in my boot directory i have 2 files very similar one is system.map the other is system26.map .
This doesnt seem right , should i maybe try renaming the system26.map to system.map after i have backed up the original system.map ????

Re: /dev/sequencer does not exist --- Found a fix for this !!!!!

Just thought id post this fix to my problem in case someone else has a similar nightmare.

I was reading through the wiki when i saw the usb midi page . Now my keyboard is not usb but still it can't hurt i thought.
And guess what i got my sound fonts to load again and my midi keyboard working.
Carefully went through all the options i had entered in the terminal to find that it was "aconnect -i" that did the trick for me so i entered this in my rc.local and rebooted to see if my midi still worked.
Hey presto i've got sound fonts and midi everytime now .
Heres my lsmod output after aconnect -i ....

Re: /dev/sequencer does not exist --- Found a fix for this !!!!!

Did you try this tip from the SBLive midi wiki:
Some users have reported that snd_emu10k1_synth needs to be preloaded in order for this to work.

I've just added it recently. It seems that that module gets magically loaded when I plug in my USB keyboard, and I always load SFs after I plug in my keyboard smile. That would explain why the USB midi howto helped you.
