help: fedora 4 on notebook

[marco.bertoli10 at tin.it]

Hi all,
i've installed Fedora Core 4 on my notebook (a Packard Bell 
EasyNote A5360).
The installation works well but i've two problems with 
the Soundcard (there is No audio) and
with the  internal 56k modem that 
isn't recognized by the system.
The Soundcard is a  Conexant 20468-31 
AC'97 audio codec which is integrated on the mainboard of the EasyNote 
A-series notebook while the modem is a  V.92 data/V.17 fax soft modem 
(Conexant 56K HSF modem drivers).
Thanks in advance to anyones that 
help me.
best ragards,
               marco
