Fedora Core 7

DarkFalcon · 11-08-2007, 03:14 AM

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:

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.

DarkFalcon · 11-09-2007, 02:19 AM

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

I am fairly new to linux.

Thanks.

DarkFalcon · 11-10-2007, 01:17 AM

Just been waiting for a while maybe got forgotten.

man asoundconf

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

DarkFalcon · 11-10-2007, 08:43 PM

Says there is not manual entry for asoundconf.

Simon Bridge · 11-11-2007, 06:15 AM

... 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?

DarkFalcon · 11-13-2007, 12:14 AM

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.

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

DarkFalcon · 11-14-2007, 02:33 AM

Can you please explain which commands or things you want me to do and what you want my to post. I don't understand what you are getting at.

DarkFalcon · 11-14-2007, 02:39 AM

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

With the system working or not working?

Commands to run, report output.
lsmod | grep snd
cat /etc/modules.conf
cat /etc/modprobe.d/alsa-base

DarkFalcon · 11-15-2007, 02:10 AM

System was not working when i posted those things.

Code:

[root@localhost Andrew]# lsmod | grep snd
bash: lsmod: command not found

Code:

[root@localhost Andrew]# cat /etc/modules.conf
cat: /etc/modules.conf: No such file or directory

Code:

[root@localhost Andrew]# cat /etc/modprobe.d/alsa-base
cat: /etc/modprobe.d/alsa-base: No such file or directory

Simon Bridge · 11-15-2007, 03:55 AM

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?

DarkFalcon · 11-16-2007, 03:16 AM

Clicking the reload modules button in the system tab in audio configuration (system-sonfig-soundcard from terminal)
