Might be a duplicate of bug 466377. When running alsactl init I get this crash and the following on the screen: bradford:~$ alsactl init ALSA lib conf.c:3366:(snd_config_hook_load) Unable to find field files in the pre-load section ALSA lib conf.c:3286:(snd_config_hooks_call) function snd_config_hook_load returned error: Invalid argument ALSA lib control.c:902:(snd_ctl_open_noupdate) Invalid CTL hw:0 Neoprávněný přístup do paměti (SIGSEGV) (core dumped [obraz paměti uložen]) bradford:~$ My hardware information is http://www.alsa-project.org/db/?f=c4173296488957629e548acf29f1743c274fd98b bradford:~$ amixer -c0 ALSA lib conf.c:3366:(snd_config_hook_load) Unable to find field files in the pre-load section ALSA lib conf.c:3286:(snd_config_hooks_call) function snd_config_hook_load returned error: Invalid argument ALSA lib control.c:902:(snd_ctl_open_noupdate) Invalid CTL hw:0 amixer: Mixer attach hw:0 error: Invalid argument bradford:~$ Headphones (with jack) work perfectly, but nothing comes out of loudspeaker.

This problem should be fixed in the alsa-lib-1.0.21-3 package.
It isn't. alsactl works only when Pulseaudio is running. bradford:~$ rpm -qa \*alsa\* alsa-utils-1.0.21-2.fc12.x86_64 alsa-utils-debuginfo-1.0.21-2.fc12.x86_64 alsa-plugins-pulseaudio-1.0.21-2.fc12.x86_64 alsa-lib-1.0.21-3.fc12.i686 alsa-oss-libs-1.0.17-4.fc12.x86_64 alsa-lib-1.0.21-3.fc12.x86_64 python-alsaaudio-0.5-2.fc12.x86_64 alsa-lib-debuginfo-1.0.21-3.fc12.x86_64 alsa-lib-devel-1.0.21-3.fc12.x86_64 alsa-oss-1.0.17-4.fc12.x86_64 bradford:~$ alsactl init Unknown hardware: "HDA-Intel" "Conexant CX20561 (Hermosa)" "HDA:14f15051,17aa211c,00100000" "0x17aa" "0x20f2" Hardware is initialized using a guess method V /var/spool/mail/matej máte novou poštu bradford:~$ paplay archiv/music/Sound_Clip/Ubuntu-startup.wav ^Cbradford:~$ sudo -i [sudo] password for root: bradford:~# vim /etc/asound.conf bradford:~# vim /etc/pulse/client.conf bradford:~# pkill -f pulseaudio bradford:~# pgrep -f -l pul bradford:~# logout bradford:~$ alsactl init ALSA lib conf.c:3366:(snd_config_hook_load) Unable to find field files in the pre-load section ALSA lib conf.c:3286:(snd_config_hooks_call) function snd_config_hook_load returned error: Invalid argument ALSA lib control.c:902:(snd_ctl_open_noupdate) Invalid CTL hw:0 Neoprávněný přístup do paměti (SIGSEGV) (core dumped [obraz paměti uložen]) bradford:~$
Could you attach your modified /etc/asound.conf file?
Created attachment 362530 [details] /etc/asound.conf
Please, comment out whole @hooks block or rename "/etc/alsa/pulse-default.conf" file. Your change in the configuration file is invalid - "ALSA lib conf.c:3366:(snd_config_hook_load) Unable to find field files in the pre-load section". Anyway, the SIGSEGV should not occur. I'll look to this problem.

Discussed at today's blocker bug review meeting. We believe this is not a blocker as long as Jaroslav's comment #10 is accurate - if you can only hit this bug by manually screwing up your ALSA config files, it shouldn't block the release. mcepl, can you please confirm that if you fix your asound.conf , you no longer hit the bug? -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Yes, confirming. I really don't have luck with ALSA bugs. This is certainly low priority bug ... ALSA shouldn't crash with whatever crap anyone puts into configuration file, but with fixed /etc/asound.conf (the one from the package) everything works as it should.
Thanks for confirming. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle. Changing version to '12'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
