No Sound After Reboot

Z3R0o · 01-05-2007, 11:43 AM

Hey guys,

I just installed Fedora Core 6 "Zod" about 4 days ago. I installed the drivers to my video card, and all is well and great, my network and printers are working fine, and so was my sound. After surfing the web for about 30 min or so, I rebooted. After the reboot, my sound went off.

Quote:

Kernel: 2.6.18-1.2869
Distro: FC6 "Zod"

I have a Realtek High Definition Audio card, integrated, of course. What's really bothering me is that when I type the command system-config-soundcard, it says no such command, and when I go to Administration in the KDE Menu, there is no Soundcard Detection icon anymore. It's as if anything related to sound just got removed or is not starting. I have the alsa drivers installed through Yum.

Quote:

yum install alsa*

Alsamixer is also not working, giving me this error when I try to run it.

Quote:

alsamixer: function snd_ctl_open failed for default: No such file or directory

My /sbin/lspci:

What version of alsa are you running (cat /proc/asound/version)? What Realtek Codec is it (head /proc/asound/card0/codec*)? Another useful piece of information would be the output from "lspci -s 0:1b -vn". That will help determine if your system is currently supported by alsa. If it is, then you have a bug in Fedora Core.

Well, I had to use

Quote:

yum list alsa*

to find out what version of alsa I have installed, because when I type

Quote:

head /proc/asound/card0/codec*

or if I type

Quote:

cat /proc/asound/version

It says no such file or directory. The alsa version I have installed is

Quote:

1.0.12-3

and Alsamixer version is

Quote:

0.9.0-0.3.rc1

As for the output from lspci -s 0:1b -vn, this is it.

Thanks again, for some additional info and response.

According to the source code, your system is supported. As to why Fedora Core isn't seeing it, I have no explanation.

Check the status of the alsasound init script with "chkconfig alsasound --list". It should be on for runlevels 2-5. If it isn't, run "chkconfig alsasound on". If it is, try running "service alsasound start" and see what messages are returned.

Maybe I'm doing something wrong, but it's saying in konsole that chkconfig and service are not commands. Did I do something wrong? I just typed

Quote:

chkconfig alsasound --list
chkconfig alsasound on
service alsasound start

I was in root, ofcourse when they were typed.

The bigger question I guess that I have is that all of the sound detection programs are not found. Last time this happened, I just re-installed alsa through Yum, but now, none of that works, I removed alsa through Yum, and reinstalled it like last time, but nothing again happened.
