Assuming you are using Gnome, do you have a Preferences -> Advanced
Volume Control, if not install the gst-mixer package.

Once you have it, take a look at the levels for all your different
Channels - you may find one that it set too low or even muted.

FWIW, I have an HP Compaq 6910p and my speakers work fine, although
the card is a little older:

[sam at samlap ~]$ lspci | grep Audio

Controller (rev 03)
