Some people have had sucess with some HP laptop by using this line in /etc/modprobe.conf
options snd-hda-intel model=hp-dv5 enable_msi=1

It seems that you have 3 sound devices on your system. Try this as a regular user :

pulseaudio -k
pulseaudio &

As root :
urpmi pavucontrol

As a user:
pavucontrol

This will give you the Pulse Audio Control panel where you can default a playback device.

If you want more info about the the hardware part of your sound system :

As root :
urpmi hwinfo
hwinfo --sound

You'll get much info, namely the driver status.

You should also run kmix and set sound levels correctly.
