It's a long time since I was familiar with this stuff so what I say below could be wrong (and perhaps I'm also over complicating things (normal for me!)). As I see it now-a-days there's no need to install any module. The kernel will suss out the hardware itself and load the appropriate module. So I suspect either you will have (a) somehow got your sound module blacklisted in /etc/modprobe.d, (b) the kernel can't find a module (i.e. package not installed or recognised), or (c) /etc/udev rules are screwed up. The latter wouldn't stop you loading the module with modprobe <module> but the kernel wouldn't load it at boot. You can check out (a) by examining the files in /etc/modprobe.d. (b) /lib/modules/<kernel name> if your module ain't listed you may have to install a firmware package (alsa-firmware?). If (c) you've got your work cut out unless you're familiar with writing/edit udev.rules.
