No sound - Intel 82801G ICH7 snd-hda-intel
I have searched these forums and the internet for a solution to this problem, but have not been able to resolve this issue.
I have a Toshiba Laptop with Fedora 7 installed in a dual boot configuration with Win XP. Sound works fine in WinXP.
My sound card appears to be detected properly in Fedora 7, however, I don't hear any sound. I have checked volume manager and everything is unmuted. The volume control on my laptop is also adjusted correctly.
Here are the specs:
Intel 82801G (ICH7 Family) High Definition Audio Controller
Module = snd-hda-intel
PCM = Conexant Analog
Alsa Driver = 1.0.14rc3
Alsa Lib = alsa-lib=1.0.14-0.4.rc3.fc7
Alsa Utils = alsa-utils-1.0.14-0.7.rc2.fc7
input: PC Speaker as /class/input/input4

Any ideas on how to get my sound working would be much appreciated.

I change a line in /etc/modprobe.conf and my T60 now works. Maybe it can help you.
Try changing:
options snd-hda-intel index=0
to:
options snd-hda-intel model=3stack

On reboot it didn't work. I read that if I enable the modem in BIOS that would correct the problem. I went back to the old modprobe.conf settings and enables the modem. That seemed to fix the problem with the T60.

This soundcard certainly has its problems in Linux.
Mine suddenly started working with the 2.6.22 kernel. If you haven't upgraded you may want to try.
When I did, the defaults were for microphone boost to be set as maximum causing uncontrollable acoustic feedback until I could get to a mixer to turn it down.

I fixed my sound problem.
The solution was to make the following edit to the /etc/grub.conf file:
At the end of the line that begins with -
kernel /boot/vmlinuz..... add the following :
acpi=off acm=off
Then reboot. This will turn off the power management which seems to have caused a conflict.

# grub.conf generated by anaconda

# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
# initrd /initrd-version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
