Hello,

I found a lot of guys with same problem.

After reading some threads here, I did the following things to make my sound works OK:

Laptop Model:
Gateway P-6831FX
Core2duo Xtreme 3ghz
4gb RAM
8800mGTS
Sound: IDT 92DT71B8X
lspci -v:

Code:
...

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)
	Subsystem: Gateway 2000 Device 0690
	Flags: bus master, fast devsel, latency 0, IRQ 2294
	Memory at f4600000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: <access denied>
	Kernel driver in use: HDA Intel
	Kernel modules: snd-hda-intel
...
1 - put following lines on /etc/modprobe.d/alsa-base.conf
Code:
options snd-hda-intel model=hp-m4 enable=1 index=0
options snd-hda-intel enable_msi=1
Note that my notebook is an Gateway, BUT i'm using model hd-m4 (HP DV laptops) because apears to have the same chipset (IDT 92DT71B8X)

The list of the supported models you can find on following place:
http://www.kernel.org/doc/Documentat...dio-Models.txt

Code:
STAC92HD71B*
============
  ref		Reference board
  dell-m4-1	Dell desktops
  dell-m4-2	Dell desktops
  dell-m4-3	Dell desktops
  hp-m4		HP dv laptops
I've tried with some Gateway listed models, but none of them worked, so, i'll continue to use the hp-m4 model.

A strange thing happend after all configurations. I needed to put/remove the headphone jacket to turn on the laptop speakers. I think that is maybe because the model hp-m4 isn't complete compatible.

So, I hope it help.

best regards.

David
