I recently dug an ISA-PnP CMI8330A up somewhere and tested it -- it
seemed to work fine. What problems are you experiencing with the driver?
from dmesg
after alsaconf (but first insertion is similar)
ALSA ../alsa-kernel/isa/cmi8330.c:338: CMI8330/C3D (SB16) PnP configure
failure
ALSA ../alsa-kernel/isa/cmi8330.c:480: cmi8330: PnP detection failed
ALSA ../alsa-kernel/isa/cmi8330.c:612: CMI8330 not found or device busy
Okay, this means it couldn't enable the SB part. Are you forcing any
resources using the sbport/sbirq/sbdma8 or sbdma16 parameters? That is,
do you provide any of these on the modprobe command line, or are they
present in your /etc/modules.conf?
If not... a CMI8330 is a chip that requires a lot of hardware resources.
It's a "Windows Sound System" and "Sound Blaster 16" on one chip. The
WSS part requires:
- 8 ports (at 0x530,0xe80 or 0xf40. typically 0x530)
- an IRQ line (5,7,9,10,11 or 12. typically 11)
- an 8-bit DMA channel (0, 1 or 3. typically 0)
The SB part adds:
- 16 ports (at 0x220,0x240,0x260 or 0x280. typically 0x220)
- an IRQ line (5,7,9,10,11 or 12. typically 5)
- an 8-bit DMA channel (0, 1 or 3. typically 1)
- a 16-bit DMA channel (5 or 7. typically 5)
The chip then adds an MPU401:
- 2 ports (0x300,0x310,0x320 or 0x330. typically 0x330).
- an IRQ line (5,7,9,10,11 or 12. typically 9)
an OPL3:
- 8 ports at 0x388
and a gameport:
- 8 ports (0x200,0x210,0x220,...,0xfe0. typically 0x200)
Most importantly in this list, 3 IRQs, and 2 8-bit DMAs. If you have
more hardware in there that requires an 8-bit DMA channel it could very
well be that there simple are none available anymore -- if you set your
parallel port to ECP, it already grabs DMA3. Or, you might have set most
of these resources to "Reserved for ISA" in your BIOS. So try if you
still have a problem with only this ISA card present, and try fiddling
with the reservation settings and "PnP OS" settings in your BIOS. If
it's a matter of an overcrowded PC, there's nothing Linux can do about it...
Thirdly; I've seen no end to trouble with 2.4 ISA-PnP. 2.6 behaves much
better. So trying a 2.6 distribution would also be good. 2.4 is really
quite obsolete.
In any case, this problem is not ALSA...
Rene.
