File: backtrace

Might be a duplicate of bug 466377. When running alsactl init I get this crash and the following on the screen:

bradford:~$ alsactl init

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.

Could you attach your modified /etc/asound.conf file?

/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.

*** Bug 481697 has been marked as a duplicate of this bug. ***

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?

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.

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bug reports from releases that are no longer maintained.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.
