Red Hat Bugzilla – Bug 275931
AC97 sound card not detected
Last modified: 2008-08-02 19:40:35 EDT
Description of problem:
Previous versions of Fedora (FC3-FC6) detected the embedded AC97 sound
controller on my Asus P4 motherboard without problem but Fedora 7 does not. That
is to say, the hardware is recognized but automatic sound card detection fails.
This is the case both with the current kernel, v184.108.40.206-65.fc7, as well as the
original release kernel, v2.6.21-1.3228.fc7
I am using ALSA driver v1.0.14
------- rpm -q alsa-lib --------
------- rpm -q alsa-utils --------
Steps to Reproduce:
1. Ran sound card detection.
2. Test Sound.
Actual Results: No sound is heard.
Expected Results: There should have been sound heard through the speakers.

The full name of the embedded sound card is: "Intel Corporation 82801EB/ER
(ICH5/ICH5R) AC'97 Audio Controller"
Please run system-config-soundcard, switch to "System" tab and select "rewrite
configuration files" and reboot your box. The USB sound device is loaded as the
first soundcard (index 0) and the AC97 fails to load then.
I rewrote the config files following your instructions and rebooted, but it did
not appear to make a difference; card is still not recognized.
Not sure what you mean by USB sound device. AFAIK, I don't have one attached.
Can you please run system-config-soundcard and attach a screenshot of the first
and second page of that utility?
I have the same pb as firstname.lastname@example.org. As requested I run system-config-soundcard,
switch to "System" tab and select "rewrite configuration files". I reboot the
system and now it's ok.
