You are very close to having sound. Everything looks good, it is just a
slight configuration issue.
Try aplay -Dhw:0,0 your_sound_file
I think you should try to find a wav file if you can, I'm not sure that
alsa converts formats.
If you don't have one, install audacity and convert a file you have to a
wav.
Also check if you have oss installed. There are programs out there that
still use OSS instead of alsa. Unless the alsa oss emulation packages
are installed, that won't work.
do yum list all | grep -i oss to find them.
if you have a .asoundrc in your home directory, move it to a backup. Do
the same with all the configuration files in /etc, /etc/asound.conf and
/etc/asound.state (might be in /etc/alsa/asound.state). Log in and out
to refresh the configuration to the default for the card.
You do have speakers plugged in, right. :-)
What does xmms do, (audio player). If it complains, go into the options
and select alsa as the device.
