I have a p4p800 running rh9.0
I was able to install the onboard nic but i am unable to install onboard sound.
I am using the driver provided by asus.
followed the instructions below.
all three commands had no errors.
rh sees a sound card. but when i try to play the sample sound i recieve a error.
Can anyone who owns this board and has sound working help me?

The three basic commands needed to build the AC97 ALSA driver
are summarize here: (These commands should be executed from the root account.)

./configure --with-cards=intel8x0
make install
./snddevices

This is a copy of the full install instructions from asus.

Instructions for Installing the ALSA Driver


1. Copy the distribution zip file to the target machine. This zip file
is password protected. The password is in the notification email.

2. Unzip the distribution zip. It will ask you for the password.

unzip <distribution-file-name>

3. You should have the ALSA driver tar file and this document.
Untar the ALSA files with the command:

tar xvzf alsa-driver-0.9.1ADI.tgz

4. You should have a directory called alsa-driver-0.9.1adi. CD to
that directory and follow the standard ALSA build instructions in
the file INSTALL.

cd alsa-driver-0.9.1adi
