Summary:                    Sound card snd-hda-intel emits NO sound
Description: 
Hi

I was merrily running Fedora Core 4 and after upgrading the kernel to
2.6.16 my sound no longer worked under Linux (it works under Windows). 
After a lot of battling I figured I may as well upgrade to FC5 now.  A
clean install, out of the box, and the sound STILL did not work.  I've
applied every available patch to date and no luck.  Tonight I installed
the Alsa 1.0.11 driver, lib and util tarballs -- all installed
successfully -- but there is STILL no sound produced.

Everything LOOKS normal.  There are no errors that I can detect.  In the X
and console versions of Alsamixer I have ALL the devices displayed and
unmuted with the volumes at max. I've removed the sound lines from
modprobe.conf and am running with alsasound and that didn't help either --
even though it says the driver has been loaded.

FYI, the OSS Volume control calls it a Realtek ALC260.  lspci refers to it
as Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller
(rev 01).


Please help.

OK then, so what must I do to fix the problem?  The sound card is being
activated by the supplied alsasound startup script in my init.d folder. 
If I run 'alsasound status' I'm told 'ALSA sound driver loaded.'

As I mentioned, after nothing was working, I installed the ALSA driver,
still nothing work, so then I removed the sound lines from modprobe.conf. 
It looks like this:
alias eth0 tg3
alias scsi_hostadapter ata_piix

Sadly there is still no sound.  Do I need any sound stuff in there?

Thanks for your time so far.  I DO appreciate it.

I see from below that the model is set to NULL and enable is set to N.

1.  How do I make alsasound script set the model=auto?
2.  Should enable=N?  How do I make it set to Y?
3.  I get no errors.  The OS thinks the card had loaded.  However,
regardless of where the volume controls are, no sound plays.
