Subject: ISA Soundblaster problem
Reply-to: [email protected]

The Maintainers list does not contain anyone for 2.4 Soundblaster modules, so perhaps some one on the mailing list is aware of a solution. My ISA Soundblaster 16waveffects worked fine in kernel 2.2 with XMMS. But I have never been successful in a varity of 2.4 kernels, the latest being 2.4.5-ac12. This is what I know:

[DMESG]
isapnp: Scanning for PnP cards...
isapnp: Calling quirk for 01:00
isapnp: SB audio device quirk - increasing port range
isapnp: Card 'Creative SB16 PnP'
isapnp: 1 Plug & Play card detected total

}modprobe sb
/lib/modules/2.4.5-ac12/kernel/drivers/sound/sb.o: init_module: No such device
/lib/modules/2.4.5-ac12/kernel/drivers/sound/sb.o: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters /lib/modules/2.4.5-ac12/kernel/drivers/sound/sb.o: insmod /lib/modules/2.4.5-ac12/kernel/drivers/sound/sb.o failed /lib/modules/2.4.5-ac12/kernel/drivers/sound/sb.o: insmod sb failed

sb: No ISAPnP cards found, trying standard ones...
sb: dsp reset failed.

So it seems that PnP finds the card, but the connections (or even the forced values) to the sb module fail. Back when this was a single processor machine, but still running 2.4 kernel, a windoze installation found the SB at the listed interface parameters.

Anyone have a solution?

Same problem without modules.conf settings, valid version of mod utilities, a web search did not help,...

TIA

I have the sound blaster 16 card on one of my athlon (on PIII i have es1731), that has one isa slot on its MB.
It works well, but i do not use isapnp nor any pnp support is enabled inside of the kernel.
running 2.4.5/2.4.6-pre2

I had a similar problem with different card (Gravi Usltrasound PnP). The solution turned out to be to avoid dma 1 channel. May be some BIOSes or ISA chipsets got the 8-bit dma channels handling wrong, but I really don't know. Btw: for me 2.2.x autodetected right, 2.4.x need explicit setting.
