Re: [Alsa-user] Alsa 0.9 / chipset 8233 : audio OK but not Midi

[Niek van der Maas]

Hi Lionel and others,

I've a KT333 motherboard with the VIA8233A chipset, and I've the same problem 
as you. "cat /proc/asound/oss/sndstat" gives me the following output:

----------
Sound Driver:3.8.1a-980706 (ALSA v0.9.0rc2 emulation code)
Kernel: Linux tussen.huis 2.4.19-gentoo-r7 #2 SMP Fri Jun 14 18:48:35 WEST 
2002 i686
Config options: 0

Installed drivers:
Type 10: ALSA emulation

Card config:
VIA 8233 at 0xe000, irq 11

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
----------


If I try to load the snd-seq-oss module (I think that's the problem) I get 
these errors:

----------
tussen root # modprobe snd-seq-oss
/lib/modules/2.4.19-gentoo-r7/kernel/sound/acore/seq/oss/snd-seq-oss.o: 
init_module: Device or resource busy
Hint: insmod errors can be caused by incorrect module parameters, including 
invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg
/lib/modules/2.4.19-gentoo-r7/kernel/sound/acore/seq/oss/snd-seq-oss.o: insmod 
/lib/modules/2.4.19-gentoo-r7/kernel/sound/acore/seq/oss/snd-seq-oss.o failed
/lib/modules/2.4.19-gentoo-r7/kernel/sound/acore/seq/oss/snd-seq-oss.o: insmod 
snd-seq-oss failed
----------

When I look at my dmesg, I see this:

----------
ALSA ../../../alsa-kernel/core/seq/oss/seq_oss.c:223: can't register device 
seq
ALSA ../../../alsa-kernel/core/seq/oss/seq_oss.c:223: can't register device 
seq
----------

Perhaps it's a problem with the driver or so? Sound is working very well, 
except for midi. Anyone with a VIA8233A who got midi working?

Thanks,

Niek.
