Description of problem:
After I updated my Asus A7N8X Deluxe (nForce 2 version 1.4) I lhave
lost sound from the onboard sound chip (nForce2 AC97 Audio Controler
(MCP)from listing in the hardware browser). Clicking on the soundcard
detection module it shows "The following audio device was detected.
Vendor: nVidia Corporation Model nForce2 AC97 Audio Controler Module:
snd-intel8x0. When I click "Play Test Sound" I get "Error: Automatic
detection of the sound card did not work. Audio will not be available
on the system. Please click OK to continue" If I boot to the original
kernel I am able to get the sound card to function as it should.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot to the 2.6.6-1.427
2. Try to play any sound files, or test soundcard
Actual Results: no sounds played
in soundcard detection: Automatic detection of soundcard did not work
Expected Results: Card should be detected as previously.
Should be able to hear sounds.
The original Core 2 (Tettnang) Kernel detects and is able to use the
onboard sound chip with out any additional configuration on my end. I
can still boot into the other kernel and play my music files without
any issues. I also have an old Adaptec 2940 Ultrawide and 2, 8 gig
hard drives that seem to function fine. Also my Logitec USB MX500
mouse is working OK. On the previous test kernels I would lose
function of the USB mouse a few minutes after boot (3-5 minutes)
Same problem here but with kerenl .435
lsmod |grep snd comes up empty.
Try using pci=nocpi in your grub boot command.
title Fedora Core (2.6.7-vanilla8stack)
kernel /vmlinuz-2.6.7-vanilla8stack pci=noacpi ro
Well I tried adding the option pci=noacpi to the grub file...(using
2.6.6-1.435.2.3 Kernel) Sound still does not work. I get about 2
seconds of the beginning of the file then silence. Going back to .358
still works fine. other ideas??
mass update for old bugs:
Is this still a problem with the 2.6.9 based update kernel ?
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat. The Fedora legacy project will be producing further kernel
updates for security problems only.
If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.
