ok, so you should be using the es1371 sound module, I think.
Try to see with lsmod if it is there.
If not try modprobe es1371 so that it installs all the needed modules and dependencies.
Do you have any error ? Ie modules missing in the kernel.
Do you have some utility soft like sndcfg, sndconfig (soundconfig stuff), even some wavplay soft if not, to try a sound ?
Do you have any audio stuff that could cause a "conflict", like a usb webcam with a microphone... if then rmmod all modules related to usb (uhci, etc.) and try again to play a sound.
Can you show us the lsmod and lspci output, if this doesn't work ?
