I had some issues on CentOS 2.6.32-279.5.2.el6.x86_64.

I had to remove this line from /etc/modprobe.d/blacklist.conf:

# sound drivers
blacklist snd-pcsp

so that I could use the "PC" speakers. Then to add that module to the kernel I did:

modprobe snd-pcsp

After that I verified basic sound functionality with alsamixer and was able to:

ogg123 - < /dev/netcat

as root without problems.
