Description of problem: During playing videos (mplayer, gmplayer, xine, it doesn't matter) sometimes the audio disappears and comes back by itself. There was no such problem under Fedora 18 on the same computer. I have two audio outputs, the onboard audio chip and HDMI audio on my Radeon card. I am using the onboard audio. In pavucontrol, the onboard audio is set to "Analog stereo duplex" on the properties page. On the output devices page, the onboard audio device is set to "Analog output". At the time when the sound disappears, it switches to "Analog headphone (unplugged)". I can manually switch back and make the audio audible again but it's a good visual feedback that it happens automatically if I leave it up on the screen side by side with the media player application.

Steps to Reproduce: 1. 2. 3. Actual results: The output device switches between "Analog output" and "Analog headphone (unplugged)" making audio flaky. Expected results: It should stay set as it was set. Additional info:
This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. 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 19 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 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is no longer maintained, which means that it will not receive any further security or bug fix updates.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.
