I have a similar problem on a Dell D600 laptop and Intel sound using Test1 and Test3. 
Bizarrely it worked fine on Test2.

The problem I have is the sound modules are not loaded at bootup, even though they are 
correctly in /etc/modprobe.conf. I haven't figured out why yet - anyone else know?

A workaround is to manually load the modules. Before logging into KDE (or presumably Gnome 
also), switch to a VT and try this:

   # lsmod | grep intel

If that doesn't find anything the modules are not loaded, so:

   # modprobe snd-intel8x0
   MC'97 1 converters and GPIO not ready (0xff00)

   # lsmod | grep intel
   snd_intel8x0           26280  1
   snd_ac97_codec         50436  1 snd_intel8x0
   snd_pcm                68872  1 snd_intel8x0
   snd_page_alloc          7940  2 snd_intel8x0,snd_pcm
   gameport                3328  1 snd_intel8x0
   snd_mpu401_uart         4864  1 snd_intel8x0
   snd                    38372  9 
snd_intel8x0,snd_ac97_codec,snd_pcm,snd_timer,snd_mpu401_uart,snd_rawmidi,snd_seq_device

Now switch back to X and login. Sound should work. I think the reason 
system-config-soundcard works is because it must do a modprobe first - maybe someone else 
can confirm this.

If it is any help, my modprobe.conf is:

# cat /etc/modprobe.conf
alias eth0 tg3
alias snd-card-0 snd-intel8x0
install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 && /usr/sbin/alsactl 
restore >/dev/null 2>&1 || :
remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r 
--ignore-remove snd-intel8x0
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd
