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.

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.

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....

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

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:

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).

Did you try the snd_isapnp=0 option?
