Summary:                    No audio output in a laptop with hda-intel....
Description: 
Hy, I managed to install the hda-intel on my laptop but my big problem is
:
The speakers inside the laptop work correctly but everytime I try to plug
a headset or some external speaker in the output used normally for it, I'd
the same result : no sound in the laptop'speakers AND no sound at all in
the external speakers. So after looking a long long time about that
problem, I didn't find anything. So maybe the function is not yet
implemented ? If it's the case, is it possible to do it because it'll be
very usefull for a lot of people ! Thanks for advance and don't hesitate
to send me a mail if I missed something ...

Actually, you can help the developers make the module autodetect the card.
All you have to do is to provide a tiny bit of information they need.
Here's how:

1) go to terminal, and run "lspci" in it. You'll get a list of your PCI
devices.

2) find your audio device in it. An example:
0000:00:1b.0 0403: Intel Corp. 82801FB/FBM/FR/FW/FRW (ICH6 Family) High
Definition Audio Controller (rev 04)

note the numbers at the beginning of the line.

3) run the commands:
"lspci -vs num:num" and "lcpci -nvs num:num" , where "num:num" are the
numbers you noted previously (without "0000:", and without the trailing
number after the dot). You should get something like this:

$ lspci -vs 00:1b
00:1b.0 Class 0403: Intel Corp.: Unknown device 2668 (rev 04)
    Subsystem: Fujitsu Limited.: Unknown device 1326
    Flags: bus master, fast devsel, latency 0, IRQ 17
    Memory at b0000000 (64-bit, non-prefetchable) [size=16k]
    Capabilities: <available only to root>

$ lspci -nvs 00:1b
00:1b.0 Class 0403: 8086:2668 (rev 04)
    Subsystem: 10cf:1326
    Flags: bus master, fast devsel, latency 0, IRQ 17
    Memory at b0000000 (64-bit, non-prefetchable) [size=16k]
    Capabilities: <available only to root>

4) paste the output as a comment here, in this bugreport. Also, please
check if all the controls in  mixer are working as expected, and tell if
they are.

After you do all this, you may expect the driver to work automagically,
without tweaking the modules.d/alsa next time.
