I tried yesterday what you had advised me to do : we draw
near the goal, but not completely reach it ! Indeed Alsa now seems to
partly recognize Midi.
First I tried this configuration of /etc/modules.conf :
> alias parport_lowlevel parport_pc
> alias char-major-116 snd
> alias snd-card-0 snd-mpu401
options snd-mpu401 snd_port=330 snd_irq=5
> alias char-major-14 soundcore
> alias sound-slot-0 snd-card-0
> alias sound-service-0-0 snd-mixer-oss
> alias sound-service-0-1 snd-seq-oss
> alias sound-service-0-3 snd-pcm-oss
> alias sound-service-0-8 snd-seq-oss
> alias sound-service-0-12 snd-pcm-oss
> alias usb-controller usb-uhci
>
With that configuration, here is what I get with lsmod command :
Module Size Used by Not tainted
snd-pcm-oss 50596 0 (autoclean) (unused)
snd-pcm 78688 0 (autoclean) [snd-pcm-oss]

It feels good except that snd-seq-oss isn't loaded. I think
it should be, shouldnt't it ?
Now here is what I get with "cat /proc/asound/oss/sndstat" :
Sound Driver:3.8.1a-980706 (ALSA v0.9.0rc2 emulation code)

Of course sound isn't working anymore but this time
Midi seems supported, which is my main goal. But if I run jazz,
it complains about "ioctl", and more precisely here are the last
10 lines (after running jazz) that I get with dmesg command :

If I try to run Rosegarden (which uses OSS /dev/sequencer device),
the whole system freezes when I try to play a Midi file : I must turn off
power to get out of troubles !
Ina second time I tried this other configuration of /etc/modules.conf :
> alias parport_lowlevel parport_pc
> alias char-major-116 snd
> options snd snd_cards_limit=2
> alias snd-card-0 snd-via8233
> alias snd-card-1 snd-mpu401
> options snd-mpu401 snd_port=330 snd_irq=5
> alias char-major-14 soundcore
> alias sound-slot-0 snd-card-0
> alias sound-service-0-0 snd-mixer-oss
> alias sound-service-0-1 snd-seq-oss
> alias sound-service-0-3 snd-pcm-oss
> alias sound-service-0-8 snd-seq-oss
> alias sound-service-0-12 snd-pcm-oss
> alias sound-slot-1 snd-card-1
> alias sound-service-1-0 snd-mixer-oss
> alias sound-service-1-1 snd-seq-oss
> alias sound-service-1-3 snd-pcm-oss
> alias sound-service-1-8 snd-seq-oss
> alias sound-service-1-12 snd-pcm-oss
> alias usb-controller usb-uhci
>
With that configuration, here is what I get with lsmod command :

snd-seq-oss module isn't still loaded. But without surprise,
sound is working well this time.
Now here is what I get with "cat /proc/asound/oss/sndstat" :
Sound Driver:3.8.1a-980706 (ALSA v0.9.0rc2 emulation code)
Kernel: Linux localhost.localdomain 2.4.18-3 #1 Thu Apr 18 07:32:41 EDT 2002 i686
Config options: 0
Installed drivers:
Type 10: ALSA emulation
Card config:

MPU-401 UART at 0x14a, IRQ 5
Audio devices:
0: VIA 8233 (DUPLEX)
Synth devices: NOT ENABLED IN CONFIG
Midi devices:
1: MPU-401 (UART)
Timers:
7: system timer
Mixers:
0: mixer00
1: mixer10
Finally the jazz test gives with that configuration the same "ioctl errors".
Here are the last 10 lines that I get with dmesg command :

Moreover the Rosegarden test still freezes my system.
Has anyone got an idea about what's happening now ?
Thanks, Lionel
