Description Juan Hernandez 2004-05-25 19:06:20 UTC
From Bugzilla Helper: 
User-Agent: Mozilla/5.0 (compatible; Konqueror/3.2; Linux) (KHTML, 
like Gecko) 
Description of problem: 
With a fresh install of Fedora Core 2 then soundcard is recognized 
and everything works fine. I can hear the sound test of 
"system-config-sound" without problems.  
Then I change the settings in "/etc/sysconfig/desktop" to use KDM 
instead of GDM as my preferred desktop manager. After rebooting, KDM 
appears and I choose KDE for the session. And suddenly the sound 
doesn't work anymore. 
I've tried setting "/etc/sysconfig/desktop" as it was before, so 
letting GDM be the desktop manager and choosing GNOME for the 
session, but sound doesn't work: I can hear nothing using 
"system-config-sound" for a test. 
As I've been trying for a long, even reinstalling the whole 
distribution, I can asure that there is no other change from the 
fresh install than the one I mention (KDM and KDE instead of GDM and 
I haven't made any change with alsamixer, kmix or similar by my own 
and looking at the settings with alsamixer they seem OK (not mute). 
Moreover, after reading some posts in Internet, I tried checking out 
"Sound Server" in KDE Control Center and also deselecting the option 
"load mixer settings" in the mixer section of Control Center, but 
nothing changes. 
Version-Release number of selected component (if applicable): 
alsa-lib-1.0.3a-2  kdemultimedia-3.2.2-2 
How reproducible: 
Steps to Reproduce: 
1.Reinstall a fresh Fedora Core 2 
2.Change settings in /etc/sysconfig/desktop from GNOME to KDE 
3.Test the sound with system-config-sound 
Actual Results:  No sound 
Expected Results:  The test sound playing

If you run 'alsamixer' from the commandline, do you get a functional

Comment 3 Juan Hernandez 2004-05-26 08:39:09 UTC
¡Sorry very much! There´s a typographic error in the "Aditional info" 
section of the report. The correct settings 
in "/etc/sysconfig/desktop" after the cgange was:


Related to your cuestion, yes, running "alsamixer" from the command 
line shows the mixer and the settings seem ok: master volume and some 
others are set, and it seems to me the same values from the fresh 
I´ve tried this form a X console in Gnome and from a text console in 
runlevel 3.

Another point that may help is that the last time I reinstalled the 
system, I didn´t format my "home" partition, so the values stored in 
the home folder or subfolders doesn´t have any effect in the problem. 

I will try to show you the sequence I followed to reproduce the bug 
and get the sound working again:

1.- Install Fedora Core 2. Format "root" and "home" partitions.
2.- Use Gdm (default desktop manager) to log in a Gnome session.
3.- Change "/etc/sysconfig/desktop" to set DESKTOP="KDE" and 
4.- Restart the system.
5.- Use Kdm to log in a Kde session.
6.- The sound doesn´t work.
7.- Reinstall Fedora without formating the "home" partition.
8.- Use Gdm to log in Gnome. Everything OK.

Comment 4 Juan Hernandez 2004-05-26 11:31:53 UTC
I´ve read a post in <a
about 4 meters for VIA soundcards in "alsamixer" that say "VIA DXS"
and must be set to 100%. The problem, according to the post, is that
KDE sets these settings to 0% everytime you start it.

I will try this afternoon the workaround, setting the right values
manually, running "alsactl store" and creating a script in
~/.kde/Autostart to run "alsactl restore" with every KDE session. I
will append another comment to tell you if that solves my problem.

After all, it seems a KDE bug with VIA cards.

Thank you.

Comment 5 Juan Hernandez 2004-05-26 14:40:28 UTC
It seems that setting the right values for "VIA DXS" with alsamixer
and  assuring KDE desn't change them solves the problem.

Comment 6 Bill Nottingham 2004-05-26 19:38:44 UTC
Assigning to kdebase, then.

Comment 7 Matthew Miller 2005-04-26 15:33:48 UTC
Fedora Core 2 is now maintained by the Fedora Legacy project for
security updates only. If this problem is a security issue, please
reopen and reassign to the Fedora Legacy product. If it is not a
security issue and hasn't been resolved in the current FC3 updates or
in the FC4 test release, reopen and change the version to match.

Comment 8 Penelope Fudd 2006-01-11 08:49:32 UTC
I've just installed FC4, and changed /etc/sysconfig/desktop to:


and I get the same problem.  The core of the problem is the command:

/usr/bin/artsd -F 10 -S 4096 -s 60 -m artsmessage -l 3 -f

It produces these error messages:
ALSA lib conf.c:1592:(snd_config_load1) _toplevel_:51:23:No such file or directory
ALSA lib conf.c:2837:(snd_config_hook_load) /etc/alsa/cards/aliases.conf may be
old or corrupted: consider to remove or fix it
ALSA lib conf.c:2700:(snd_config_hooks_call) function snd_config_hook_load
returned error: No such file or directory
ALSA lib pcm.c:1969:(snd_pcm_open_conf) Invalid type for PCM default definition
(id: default, value: cards.pcm.default)

And it produces a pop-up window, which I'm attaching.

Comment 10 John Thacker 2006-10-25 19:53:20 UTC
Changing Version to FC4, per above comment.

Comment 11 Christian Iseli 2007-01-22 10:06:18 UTC
This report targets the FC3 or FC4 products, which have now been EOL'd.

Could you please check that it still applies to a current Fedora release, and
either update the target product or close it ?


Comment 12 petrosyan 2008-02-13 04:46:17 UTC
Fedora Core 4 is not maintained anymore.

Setting status to "INSUFFICIENT_DATA". If you can reproduce this bug in the
current Fedora release, please reopen this bug and assign it to the
corresponding Fedora version.
