David,

There is no sound, although alsamixer works, and the volume is up. And yes, 
there is an internal modem.

As for the hardware, Im fairly sure it is correctly set. It used to show up 
in the kernel options as PCI device, I8x0. Now it shows up as AC97, but see 
snippet below.

'aplay -l' shows:

**** List of PLAYBACK hardware devices ****
card 0: I82801DBICH4 (Intel 82801DB-ICH4), device 0: Intel ICH (Intel 
82801DB-ICH4)
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: I82801DBICH4 (Intel 82801DB-ICH4), device 4: Intel ICH - IEC958 
(Intel 82801DB-ICH4 - IEC958)
Subdevices: 1/1
Subdevice #0: subdevice #0

Some settings stuff now:

In the kernel config, the options I have selected are:

Device Drivers ---> Sound --->
<*> Sound Card Support

Advanced Linux Sound Architecture --->
<*>Advanced Linux Sound Architecture
<*> Sequencer Support
< > Sequencer Dummy Client
<*> OSS Mixer API
<*> OSS PCM (Digital Audio) API
<*> OSS Sequencer API
< > Verbose printk
< > Debug

PCI Devices --->
<*> Intel/SiS/Nvidia/AMD/ALi AC97 Controller

Note: In the PCI device list above, there is also a new option for 
'Intel/SiS/Nvidia/AMD MC97 Modem (EXPERIMENTAL)'. This is not selected.

Dmesg shows the device quite hapily:

intel8x0_measure_ac97_clock: measured 49294 usecs
intel8x0: clocking to 48000
ALSA Device List:
#0: Intel 82801DB-ICH4 with STAC9750/51 at 0xf4fff800, irq 5

Now, further into the boot process, after INIT, I get:

Loading ALSA modules
Loading: snd-card-0
FATAL: Module snd_intel8x0 not found.
Restoring mixer levels.

The /etc/modules.d/alsa looks like this :

# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore

## ALSA portion
alias snd-card-0 snd-intel8x0
## alias snd-card-1 snd-ens1371
## OSS/Free portion
## alias sound-slot-0 snd-card-0
## alias sound-slot-1 snd-card-1
##

# OSS/Free portion - 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
## OSS/Free portion
## alias sound-service-1-0 snd-mixer-oss
## alias sound-service-1-3 snd-pcm-oss
## alias sound-service-1-12 snd-pcm-oss

alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss

options snd cards_limit=1

Now Im even more confused than I was before.

Steve.
