Welcome back, Jane! I very much liked your artistic-centered (but 
nonetheless often technical) contributions, so it's really good to see 
you coming back. :-)

In case the qi kernel doesn't work, here's an answer to your questions.

They're normally in subdirectories under there, but I'm not sure if 
that's required. The kernel/ directory is for modules built from the 
kernel source; misc/ for others. That also means the packaging system 
(if you'll ever use it) will not touch misc/, so that's a relatively 
safe place to put "custom" modules. This one, I'd install in

That should work on Debian. Then it should try to load it on the next 
boot. Perhaps that fails. You can see if you load it manually.

Those are useful for dealing with the device, but don't help for finding it.

Some commands that my help you:
- lsmod: show loaded modules.
- insmod: insert module file by hand. Takes a path to a file and module
   arguments. Can be useful sometimes, but normally modprobe is better.
- modprobe: insert module. Takes a module name (not a filename!), which
   must be installed in /lib/modules/... Arguments are taken from
   /etc/modprobe.d/*, not
   from the command line.

Try modprobe and see what error message it gives you. If the module is 
there, but you still have problems, check /dev/sndstat for what the 
kernel has available.

Cool. :-D
