I used above command with a C&P as well. I've also verified the
command to my another FC7 box which has sound worked well, it also
shown a blank result as well.

Actually, I tried without echo $? first, it display lots of
parameters, seems file. I can try the echo $? again, what is the
correct command for it? Is following command correct?
rpm --verify alsa-lib-1.0.14-1.rc4.el5.i386
lsa-utils-1.0.14-3.rc4.el5.i386; echo $?

I can use vlc to play the *.wav or other audio files, but I tried to
figure out where is the block or missing link with the audio. Right
now, no sound when I run vlc to play audio files. If I could check and
play in some means with low level driver first, I guess I could find
if the problem is high level applications or low lever drivers. Seems
that the drivers all there, but don't know if them are working or not.
Thank you.
