Created attachment 892115 [details] pulseaudio log that was captured while reproducing the problem described in the ticket Description of problem: I have an Acer Aspire 8920G notebook with integrated 5.1 surround sound. In pavucontrol I did select Built-In Audio Analog Surround 5.1, however when I start playback of a media file (no matter if just music or video) I clearly hear that it is not playing in surround mode. However, if I go to pavucontrol to the "Playback" tab, click on the "Built-In Audio Analog Surround 5.1" button which is displayed next to the application that is currently playing, select some other entry in the menu (for me the other option that it lists is RV635 HDMI Audio), then click the same button again and re-select the old option "Built-In Audio Analog Surround 5.1" - then surround sound starts working and I can hear sound on all channels. The setting gets lost when the movie/song finishes, so basically I have to repeat the above steps for each media that I am playing. Version-Release number of selected component (if applicable): I had this problem right from the beginning of my Fedora 20 installation. Currently using: kernel-3.14.2-200.fc20.x86_64 pulseaudio-libs-4.0-13.gitf81e3.fc20.x86_64 pulseaudio-libs-devel-4.0-13.gitf81e3.fc20.x86_64 pulseaudio-libs-glib2-4.0-13.gitf81e3.fc20.x86_64 pulseaudio-module-bluetooth-4.0-13.gitf81e3.fc20.x86_64 pulseaudio-4.0-13.gitf81e3.fc20.x86_64 pulseaudio-utils-4.0-13.gitf81e3.fc20.x86_64 alsa-plugins-pulseaudio-1.0.27-2.fc20.x86_64 pulseaudio-module-x11-4.0-13.gitf81e3.fc20.x86_64 pulseaudio-libs-4.0-13.gitf81e3.fc20.i686 How reproducible: Already described above, start playing a media file, go to pavucontrol, select any other output mode and then re-select 5.1 to get it working. Additional info: I am attaching a pulseaudio log. I did exactly what I was describing: 5.1 is set as default, I start to play a video, then launch pavucontrol, click the output button which by default shows 5.1, select something else, then re-select 5.1 and observe that surround starts working. I then quit the playback and quit pavucontrol.
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 EOL if it remains open with a Fedora 'version' of '20'. 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. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 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, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. 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.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 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. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
