Well, having some idea of your exact hardware setup would help - debian often has a limited subset of drivers, but i'd start with installing and using lshw (debian suggests using hotplug for usb, and lspci for pci, but lshw tends to work for me, mostly) to identify the sound card, and following debian's documentation for setting up alsa

The bit about realtek sound cards looks especially interesting, since most cheap and cheerful built in soundcards are realtek, and you apparently need to download and install those drivers.

Squeeze it harder! Ok, seriously, you could just be missing the right driver. There is not much info here to go on. What does lspci show you? Or lsusb? What kind of platform is it?

BTW, chuck the pulseaudio, it won't help you. Install alsa-libs and alsa-tools.
