Having not been bombarded with responses, I thought perhaps I should offer more 
details.  Here goes:

Sound problem 2/15/07

Following the solutions guide,
http://doc.gwos.org/index.php/Comprehensive_Sound_Problems_Solutions_Guide
I get:

aplay -l

 From the above, I conclude that things are installed properly, and should work. 
  They do not.  So, more results follow.

Note from Ubuntu forum:

ATTENTION:

Due to an unavoidable ABI change the Ubuntu 6.06 and Ubuntu
6.10 kernel updates have been given a new version number, which
requires you to recompile and reinstall all third party kernel modules
you might have installed. If you use linux-restricted-modules, you
have to update that package as well to get modules which work with the
new kernel version. Unless you manually uninstalled the standard
kernel metapackages (linux-386, linux-powerpc, linux-amd64-generic), a
standard system upgrade will automatically perform this as well.

Is emu10k1 third party?  To what does the pronoun "this" in the last sentence refer?


Any offerings are most welcome.

-Denis
