since the new sound stuff got integrated I have had a hard time
configuring kmod to properly use my Opti 931. Basically, the soundcore
module would not unload and when reloading the mad16 module, the mixer
would not work.
I have fixed this by making the unload_mad16() function look just like
the unload_ms_sound() function in ad1848.c -- for some reason the
mixer unloading part was left out.
Now, I do not know if this breaks something else. I know nothing about
the sound stuff and found this by just skimming through the sources.
To me it seems that unload_mad16() could simply contain a call to
unload_ms_sound().
Also, I had no idea how to make a proper patch file. I hope I have
done it correctly but offer my excuses in case I did not.
Concerning module unloading, I have a cron entry that does "rmmod -a"
but why does it have to execute twice before the modules get unloaded?
