sb 16 pro + alsa 0.5.12a + k 2.4.17

sb 16 pro + alsa 0.5.12a + k 2.4.17

[Ludovic Drolez]

Hi !

I trying to make my SB16Pro work (not pnp). I've compiled alsa with no isa pnp support but 
when I insert the module I get the following messages:

/lib/modules/2.4.17-k6/misc/snd-card-sb16.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or 
IRQ parameters
/lib/modules/2.4.17-k6/misc/snd-card-sb16.o: insmod 
/lib/modules/2.4.17-k6/misc/snd-card-sb16.o failed
/lib/modules/2.4.17-k6/misc/snd-card-sb16.o: insmod snd-card-sb16 failed

and dmesg says:

isapnp: Scanning for PnP cards...
isapnp: No Plug & Play device found
snd: Sound Blaster 16 soundcard #1 not found at 0x220 or device busy
snd: Sound Blaster 16 soundcard #2 not found or device busy

BUT, If I switch to k 2.2.19 and recompile alsa 0.5.12 or 0.5.11 it works perfectly !!! 
So, Yet Another Kernel 2.4. bug ????

Cheers,

   Ludovic Drolez.

Very clear error message: please supply proper parameters for the
snd-card-sb16 module. "modinfo snd-card-sb16" will tell you what
parameters the module accepts.

I don't think so. I think you either forgot to specify the correct
module parameters, or you somehow loaded the kernel Soundblaster
driver.

Did you read the file Documentation/Changes in the kernel source tree?
The linux-2.4 kernels need quite some new userland programs to work
properly.

I have supplied all parameters you can imagine. And my launch script is the same for k 
2.2.19, and for 2.4.17...

Yes, I have upgraded dozen of packages (a Debian 2.2 with bunk's packages).
What I find strange is: the kernel is scanning for pnp card although I told alsa to ignore 
pnp card....

And did you run "update-modules && depmod -a"?

It could also be that it is compiled into the kernel itself. See
/proc/ioports to see which driver claims the ports.

OK, Adrian Bunk's packages work fine.

You told the kernel that you want ISA PnP support, so the kernel will
scan for cards. Recompile your kernel and disable PnP support.

sb 16 pro + alsa 0.5.12a + k 2.4.17 = alsa isapnp bug

[Ludovic Drolez]

Hi !


I recompiled alsa with the '--with-debug=detect' option to find why alsa 0.5.12a works 
perfectly with my 2.2.19 kernel but not with a 2.4.17.
Both kernel are compiled with ISAPNP but Alsa is compiled '--with-isapnp=no' because the 
SB16Pro is not PNP.

With k 2.2.19, 'modprobe snd-card-sb16 snd_irq=5' gives:

Feb 11 18:46:52 red kernel: snd: SB [0x220]: DSP chip found, version = 4.13

Ok, no problem at all, now with 2.4.17:

Feb 11 19:50:57 red kernel: snd: isapnp failed for SB16
Feb 11 19:50:57 red kernel: snd: Sound Blaster 16 soundcard #1 not found at 0x220 or 
device busy
Feb 11 19:50:57 red kernel: snd: Sound Blaster 16 soundcard #2 not found or device busy 


Problem: Alsa tries to detect a PNP card even with '--with-isapnp=no' !
Indeed the 1st line (...isapnp failed...) is output by card-sb16.c line 536.
There is a bug here because 'snd_sb16_isapnp()' should not be reached because of a '#ifdef 
__ISAPNP__' and because 'CONFIG_ISAPNP=0'.

My quick fix to make my card work with 2.4.17:


--- include/driver.h.orig       Mon Feb 11 22:04:50 2002
+++ include/driver.h    Mon Feb 11 22:05:02 2002

So there must be a problem with all the #if but I do not know exactly where.

(CONFIG_ISAPNP is redefined somewhere but it should not be).


Cheers,

   Ludovic Drolez.

Did you try the snd_isapnp=0 option?
