Sound working but not MIDI
 
I haven't been able to get midi playback working on Slackware 10. I have an on-board sound card, AC'97, Intel8x0. I can play MP3's and CD's no problem. The Linux MIDI-HOWTO doesn't help me, and I've searched google and these forums, but I haven't found any advice that has helped me to get midi working.

Here is the output of '/sbin/modprobe -l | grep midi':

Code:
/lib/modules/2.4.26/kernel/drivers/sound/v_midi.o.gz
/lib/modules/2.4.26/kernel/drivers/usb/usb-midi.o.gz
/lib/modules/2.4.26/kernel/sound/acore/seq/snd-seq-midi-emul.o.gz
/lib/modules/2.4.26/kernel/sound/acore/seq/snd-seq-midi-event.o.gz

/lib/modules/2.4.26/kernel/sound/drivers/snd-serialmidi.o.gz
/lib/modules/2.4.26/kernel/sound/drivers/snd-virmidi.o.gz
The output of 'lsmod' that has to do with sound:

soundcore              3396  4  [snd]
My /etc/modules.conf file has:

Code:
alias char-major-116 snd
alias char-major-14 soundcore
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss

alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
alias snd-card-0 snd-intel8x0
alias sound-slot-0 snd-intel8x0
Any ideas on what to do, or where to go for help/info?

Download and installpkg timidity from linuxpackages.net. It works like a charm.
The problem is afaik, the onboard sound card does not have a midi capability, so you have to emulate it and that's what timidity does.

Thanks. Midi is not that important to me, I'm just putting my Linux system to the test, so to speak, just seeing what I can do with it.

Is it possible to emulate /dev/midi device with timidity ?
I know it can play midi files from the command line, but i would like to let other programmes play midi files too, hopefuly by emulating the midi device somehow.
My sound card is onboard AC'97 too, it has no midi device for sure.

This page (http://www.linuxfocus.org/English/Se...ticle259.shtml) seems to cover it, but I've been unable to compile it in. Grrr.
