Most likely pulseaudio, reassigning. I dont know how to help diagnose what's going wrong here though... Interesting: Analog output works correctly with all components (ALSA, Pulseaudio, Phonon, KDE volume control, Amarok, etc). The problem seems to be centered in the digital output. 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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 Fedora 19 is no longer maintained, which means that it will not receive any further security or bug fix updates.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. |
Created attachment 852014 [details] alsa-info.txt I'm trying to use the audio digital output (SPDIF IEC958) of my computer. After many hours of try-and-error, and a lot of searching in the internet, I have gotten it to work, but in a rudimentary and not friendly way: Command "aplay mysong.wav" works, so ALSA works, but KDE sound (for example, amarok) doesn't work. Why? Well, to get ALSA to work, I had to uninstall "alsa-plugins-pulseaudio" package, so "kde-settings-pulseaudio" too. If I re-install both packages, then ALSA doesn't work any more ("aplay" command doesn't work, and KDE sound doesn't work). So the only way to get a bit of sound through SPDIF is by uninstalling both packages. The thing is even more strange: For the "aplay" command to work, I had to run "alsamixer" command, and, after playing a lot with the controls, set the "S/PDIF Playback AC97-SPSA" item to zero. I don't know why. Additionally (it is probably normal), "S/PDIF Playback Source" item has to be set to "PCM", and "S/PDIF" item has to be enabled. Another strange thing: "Master" volume item has no effect in the volume, so the only way I can change the volume is by using my speakers' volume control. Volume can't be changed by software. As I said, I can get sound only by using the "aplay" command (it seems to be a command from ALSA). No sound in KDE apps. I would like to use Amarok, and use the KDE volume control. Phonon (the KDE sound system) seems to be well configured: - Audio hardware setup: - Sound card: Internal audio. (the only card in the list) - Profile: Stereo digital output (IEC958). - Sound device: Playback (Internal Stereo digital audio(IEC958)). (the only device in the list) - Connector: Digital Output (S/PDIF). (the only connector in the list) - Engine: GStreamer. (the only engine in the list) Perhaps the problem could be in pulseaudio or in gstreamer, or perhaps in ALSA, or perhaps in the communication between all of those components... I don't know. Is it me, or there are too many components? I mean: ALSA, Pulseaudio, Phonon, Gstreamer... It is a mess, too much complexity, an invocation to problems. Shouldn't it be more easy? Well, that was a philosophical question. Back to my problem... To help you to help me :), I have run the "alsa-info" command, that seems to generate a lot of information, and I'm attaching the output file to this thread. I will thank you for any clue on how to make sound (digital output) run on KDE. (I didn't know which Fedora component assign this thread to. I have assigned "phonon", but be free to re-assign to the correct one (perhaps alsa or pulseaudio or gstreamer or ...))
