Fedora Core 7 - Sound System not working.


I have been using fedora core 7 for two weeks now and have just about got all the problems sorted when i booted kde and this message greets me:


Code:
 Sound server informational message:

Error while initializing the sound driver:

device: default can't be opened for playback (No such file or directory)

The sound server will continue, using the null output device.
The sound system was working fine yesterday. I have seen other threads with this problem but their solutions either are obsolete or don't work.

As requested by the forum sticky:

Output from "/sbin/lspci"

Code:
00:00.0 Host bridge: Intel Corporation 82865G/PE/P DRAM Controller/Host-Hub Interface (rev 02)

Please help me with this if anyone can.

Someone who reads the stickies deserves a quick response:

You may need to execute the asoundconf(1) set-default-card macro.

Hi, Thanks for the quick help

But could you please explain to me how I "execute the asoundconf(1) set-default-card macro."

I am fairly new to linux.

Thanks.

man asoundconf

When you see an instruction that has a number in brackets, it is a reference to a man(1) page.

... from the man page:
Code:
 asoundconf - utility to read and change the user’s ALSA library config-
uration
Type "man asoundconf" into google...

asoundconf list (gets the names of the available cards)
asoundconf set-default-card CARDNAME

Note: when reporting the result of commands, it is best to copy the command and the result to a code-box in the forum than to describe the result like you did.

So, for me, the commands look like:
Code:
$ asoundconf list
ICH5
$ asoundconf set-default-card ICH5
See?

Okay, I used the soundcard config utility ( "system-config-soundcard" from terminal as su) and i play the sound test and i get nothing, then i go to the "system" tab and click "reload drivers" then apply the changes and the test sound works and my sound works.

The problem now is whenever i boot or reboot my system it goes back to the error and no sound again, so i have to reload the drivers again.

00:1f.5 Multimedia audio controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02)

hmmm... that's the same card I have. The main modules seem to be snd_intel8x0 and snd_ac97_codec ... lets have a look at your alsa modules before you "reload modules" (lsmod | grep snd) and the content of /etc/modules.conf (cat /etc/modules.conf - don't worry if you don't have one.) Then try using modprobe from CLI.

If that doesn't result in a persistent loading, I guess you can always add the modprobe commands to /etc/rc.local

In the system tab of "Audio Configuration" window (system-config-soundcard from terminal) under sound test tab the selected card area contains this writing:

Code:
Vendor: Intel
Model: Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller
Module: snd-intel8x0

Good grief!

/sbin/lsmod | grep snd (lsmod is one of the basic utilities)
ls /etc | grep mod (modprobe is supposed to have a configuration file - somewhere, check your modprobe man page, see if it tells you any different from above.)

How are you reloading the modules?
