Hi everybody,
I've just bought a PC mainly in order to control a Midi synthesizer.
This PC is based on a DFI motherboard (AD70-SC model) with KT266A/VT8233
Via chipset. I've installed the RedHat 7.3 distribution of Linux which is based on
2.4.18 kernel. At the beginning, sound didn't work at all. So I searched through
internet and found drivers for VT8233 chipset and 2.4.18 kernel at the Via
website (http://www.viaarena.com). Then sound started to work but not midi
(still no device for /dev/sequencer).
Then I've installed Alsa 0.9rc2 (drivers, libs and utils packages).
Compilation (--with-debug=full --with-sequencer=yes --with-oss=yes
--with-isapnp=no) and installation ran without any problem, but the
situation remains the same : sound works very well (I can play samples,
movies, etc.) but midi seems to be completely "ignored", both by Alsa
(jazz complains that it can't find any midi port) and OSS emulation
(see below /proc/asound/oss/sndstat).
Here is my /etc/modules.conf :
alias parport_lowlevel parport_pc
alias char-major-116 snd
alias snd-card-0 snd-via8233
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
Here is what I get with lsmod command after login in KDE environment :

jbd 49400 5 [ext3]
As it can be seen : all sound modules are well loaded except sequencer
and midi ones.
Now here is the result of "cat /proc/asound/cards" :
0 [card0 ]: VIA8233 - VIA 8233
VIA 8233 at 0xe000, irq 5
And now the result of "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:
VIA 8233 at 0xe000, irq 5
Audio devices:
0: VIA 8233 (DUPLEX)
Synth devices: NOT ENABLED IN CONFIG
Midi devices: NOT ENABLED IN CONFIG
Timers:
7: system timer
Mixers:
0: mixer00
I'm worried by those "NOT ENABLED IN CONFIG" messages ! I'm
sure that my motherboard has Midi support because it is written inside the
provided manual and a Midi connector is present at the backside of the PC.
Moreover I checked the jumpers of the motherboard : they are set to enable
audio chipset and anyway sound works well.
I also played with bios settings without more success :
- The "Midi Port Address" parameter is by default set to 330. Other
possible choices are 300, 290 and disable. None works.
- The "Midi Port IRQ" is by default set to 10. Other possible choice is
5. But setting it to 5 makes the "Card config:" become "Via 8233 at 0xe000, irq 10"
in the /proc/asound/oss/sndstat, but midi remains "NOT ENABLED IN CONFIG".
Finally I looked the logged events in /var/log/messages, but didn't see any
alsa stuff despite the debug switch set to full during compilation. However, there
are some "worrying" messages logged by the kernel during reboot. Here they are :
Jul 29 23:51:28 localhost syslogd 1.4.1: restart.
Jul 29 23:51:28 localhost kernel: klogd 1.4.1, log source = /proc/kmsg started.

At that point, I'm completely stuck and don't see what to do
now to make my computer communicate with my synthesizer...
So any help would be appreciated.
Thanks, Lionel
