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.
