Description of problem:
On my linuxbox, with a clean Fedora Core 5 installation, audio is correctly
configured with snd-hda-intel module. My soundcard is a 82801G (ich7 family)
rev. a. When i try to reproduce some audios i can hear sound and music, but
there's always an high frequency noise and if i change volume on alsamixer audio
stops, my device become mute and i have to reboot to have audio up.
After a general update, with kernel version 2.6.16-1.2133_FC5smp and alsa
1.0.11rc4 i've got the same issues.

Version-Release number of selected component (if applicable):
Kernel Version 2.6.16-1.2133_FC5smp
Alsa drivers 1.0.11rc4
Fedora Core 5

How reproducible:
Install Fedora core 5 on a pc with 82801G ich7 audio controller
play a sound


Steps to Reproduce:
1. Install fedora core 5
2.play sound
3.(eventually) perform a yum update
  
Actual results:
