Description Espen Stefansen 2009-05-29 06:42:03 EDT

Hmm, this is probably just an issue of an incomplete mixer initialization. Could you please read this mail from Adam: https://www.redhat.com/archives/fedora-devel-list/2009-April/msg02321.html Then, please attach amixer outputs before and after you tried to fix the situation with alsamixer!
Comment 2 Espen Stefansen 2009-05-29 07:34:32 EDT
Yep, you were right. It was an issue of an incomplete mixer initialization. I installed gst-mixer and turned on IEC958, and the sound came out of the headphones. Here's the diff from amixer before and after: [root@itse6848-2 ~]# diff -u amixer-before.txt amixer-after.txt --- before.txt 2009-05-29 13:24:10.000000000 +0200 +++ after.txt 2009-05-29 13:30:33.000000000 +0200 @@ -20,7 +20,7 @@ Simple mixer control 'IEC958',0 Capabilities: pswitch pswitch-joined Playback channels: Mono - Mono: Playback [off] + Mono: Playback [on] Simple mixer control 'IEC958 Default PCM',0 Capabilities: pswitch pswitch-joined Playback channels: Mono

Comment 4 Lennart Poettering 2009-05-29 08:21:12 EDT
Hmm, that is weird. You turn on spdif and this makes the headphones work? Hmm, Jaroslav, what's going on here?
Comment 5 Espen Stefansen 2009-05-29 08:35:14 EDT
Just to clarify. Before turning on IEC958: - When the laptop is in the docking-station and no headphones are connected, sound plays from the builtin speakers - When headphones are connected to audio jack on laptop, sound plays from the headphones - When headphones are connected to audio jack on the docking-station, sound plays from the _builtin speakers_ After I turned on IEC958: - When the laptop is in the docking-station and no headphones are connected, sound plays from the builtin speakers - When headphones are connected to audio jack on laptop, sound plays from the headphones - When headphones are connected to audio jack on the docking-station, sound plays from the _headphones_ Turning on IEC958 makes everything work as it should.

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 8 Peter van Hooft 2009-07-01 13:27:05 EDT
I want to report the same problem against an uptodate 11 installation on a Dell Latitude D630 laptop when docked. This problem has plagued me since at least fedora 10. Usually, toggling the IEC958 switch in any mixer that supports it solves the problem. When it doesn't, installing the alsa-kmdl from atrpms sometimes works. I'll attach my /tmp/alsa-info.txt
Comment 9 Peter van Hooft 2009-07-12 14:20:26 EDT
Update: when I run pavucontrol, I can switch audio output to 'Output Digital Stereo (IEC958) + Input Analog Stereo' which makes audio output fully functional, even the gnome volume applet can now control volume correctly. Comment: Perhaps pavucontrol should be installed by default? It seems audio+video control for docked laptops is severely lacking. It would be nice to have some sort of profile management for systems that can operate in different hardware configurations (like there is for networks).
Comment 10 Bug Zapper 2010-04-27 10:34:10 EDT
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. 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 '11'. 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 11'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 11 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
Comment 11 Bug Zapper 2010-06-28 08:44:44 EDT
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 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.
