Blank result? I'm skeptical about that. <*scratching head*>

The /tmp/asound file should contain at least the file names that it
found. And I can't believe that trying to play something would remove
the contents of those files. 1) It would have to be root and 2) IIRC, we
can't remove stuff in /proc as it is from the kernel and not a real file
system and 3) We could only change the contents of *some* things.

I tested the above command with a C&P and it worked. Maybe you had a
typo or the frustration is getting to you and you examined the wrong
file?

The above command s/b rpm --verify .... ; echo $?

If you meant "||", it would still be logically incorrect as we want to
see the return value, regardless.

You need an application to do that. I've only used various Gnome desktop
facilities. The file manager (Nautilus?) should do that when you double
click a sound file. I'll test ... BRB

Yep. I went to /usr/share/sounds/alsa, using file manager, and it opened
totem and played the sounds. This means that you could open totem
directly, or any other sound playing application and try it.
Unfortunately, unless we suspect broken applications are the problem,
this really only is the same as what you tried to do originally, less
the CD.
