That's good news. Congratulations!
(It's strange that you couldn't find alsaconf though - did you run the command
updatedb again
AFTER you installed the rpm-packages?
If not, the command
locate alsaconf would not find alsaconf! )
(Also, after you installed the rpm packages of alsa the
first time - if you then did run it again, then you certainly would have gotten the message that it's already installed.)
If there's other questions in the future, just post it here - and we will do our best to help.
Have a nice day!
