sound card modules has been lost
 

Recently, I installed `hsfmodem' driver, for my external modem, provided by `linuxant'. The modem is working correctly, but I lost my sound card. Seems that `hsfmodem' replaced sound card modules. When I run `alsaconf', it say that it didn't find any PCI or PnP sound card on my system.

I use Debian Lenny on Acer Extensa 4220 machine, and its manual said that it have an `Intel High Definition Audio'. And `lspic' says that I have a `ICH8 Family' chipset.

I can't remember exactly what kind of module was loaded for the sound card before installing `hsfmodem'. That was something like `intel-snd-...'. And now, `lsmod' says that there's no sound module loaded.

Any idea? Can you tell me which package should I install in order to restore old sound card modules?

And ...
`modprobe snd-hda-intel' is not working, say:

FATAL: Module snd_hda_intel not found.
FATAL: Error running install command for snd_hda_intel

The problem dosen't solved yet.
Any idea?
