problem configuring sb16 and alsa

Hi Greg. So you have a 2.4.18 kernel on another machine with sb live, and the mods are in /lib/modules/2.4.18/kernel/sound? Now you have another machine with the sb16 and you're trying to get the modules to load but they are not loading? And you have them located in /lib/modules/2.4.18/kernel/sound? What error do you get? My problem was that modprobe couldn't locate the module even if I was in the current directory. This is bad error handling on the part of modprobe, for it should have said something equivalent to could not load dependency module xxxx.o. In my case, it turned out that it couldn't locate snd_timer.o, snd-mixer-oss.o, and others. I found this out when I did an insmod snd-cs4236 in my case. I fixed the problem by putting all the modules in the same directory beta9 /lib/modules/2.4.18/misc. Everything worked fine after that. In your case, you may want to add some paths into /etc/modutils/paths. If it won't scan recursively however, you're going to add all the directories that are above the one for your sound card. Hope this helps, and feel free to ask me something if I wasn't being specific enough.

I first tried loading everything by hand, but when I got the same results then as I'm getting now, I decided to try the modules.conf. When that also didn't work, I upgraded to beta 12 in hopes of getting that to work.

Also, don't install your modules in /lib/modules/2.4.18/kernel/sound tree, because this is in conformance with the kernel 2.5.x tree. I have found that 2.4.18 has problems with this. What I did was build the code as follows: ./configure --with-oss=yes --moddir=/lib/modules/2.4.18/misc. I created the misc directory manually. I then wrote a script that loads the sound module, and runs alsactl to restore the previously saved mixer configuration.
