Works with the Intel HD audio driver which should be compiled as a module for sound to function:
CONFIG_SND_HDA_INTEL=m

To enable sound support for this machine, use the following setup:

Device Drivers  --->
    Sound  --->
        <M> Sound card support
        Advanced Linux Sound Architecture  --->
            <M> Advanced Linux Sound Architecture
            <M> Sequencer support
            < > Sequencer dummy client
            <M> OSS Mixer API
            <M> OSS PCM (digital audio) API
            [*] OSS PCM (digital audio) API - Include plugin system
            [*] OSS Sequencer API
            Generic devices  --->
                <M> Dummy (/dev/null) soundcard
            PCI devices  --->
                <M> Intel HD Audio

After the kernel is setup for sound, we need alsa to detect and setup the configs:
# alsaconf
The card should be now detected. Alsaconf will add the following to your modules.conf:

# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-hda-intel
# module options should go here

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

To hear any sound, we still have to unmute the audio channels:
# alsamixer
Unmute (m key) and set the volume (arrow keys) and then save your settings:
# alsactl store

If you use xmms, make sure the output plugin is set to ALSA. KDE needs no modification after the above has been setup.
