Created attachment 925885 [details] Output from dmesg from the 3.15.8-200.fc20.x86_64 kernel Description of problem: Although sound works under Windows 8, I cannot get any sound under Linux Version-Release number of selected component (if applicable): 1.0.27.2-2.fv20 How reproducible: Always Steps to Reproduce: 1. Boot the computer 2. Try to use any software that plays sounds, eg Audacity, Firefox/youtube 3. Actual results: Silence, even though the software shows that sound is being processed Expected results: I should hear the sound Additional info: It does not matter whether I use headphones or the built-in speakers. I reported the problem to the kernel maintainer group (https://bugzilla.redhat.com/show_bug.cgi?id=1062099), but I suspect that it is really an ALSA problem rather than in the kernel. There are no error messages in the boot log that would flag it as a kernel problem. cat /proc/asound/cards gives 0 [HDMI ]: HDA-Intel - HDA ATI HDMI HDA ATI HDMI at 0xf0344000 irq 46 1 [Generic ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0xf0340000 irq 16 Running alsa-info.sh creates a file at: http://www.alsa-project.org/db/?f=0a1e4f9d19968eae0192124bff356002a88c428b I have updated the BIOS to the latest version. I have verified using alsamixer and pavucontrol that the output is turned on and has volume. Nothing works. I tried disabling pulseaudio but it made no difference.
you should not overwrite pcm.default if you are using pulseaudio !ALSA configuration files !!------------------------ !!System wide config file (/etc/asound.conf) # # Place your global alsa-lib configuration here... # # GF mod pcm.!default { type hw card Generic } ctl.!default { type hw card Generic }
I tried that in a a desperate attempt to get sound working. It did not help. (I do not understand the relative roles of ALSA and pulseaudio.) After removing the file, sound still does not work. I have searched the web for ideas and that was one of them. Nothing I have found has made any difference.

Do you have any suggestions on how I would do that?
I did not understand your comment. I looked in the dmesg output and found the text "(try booting with the "irqpoll" option)". I have done that. It has not fixed the problem of sound not working, but it has got rid of that message from dmesg. I have attached the new dmesg output.

I have upgraded to Fedora 21 and there is no change in the problem. I get no sound from the analog sound system (and have no way of checking the HDMI). I am using 3.17.6-300.fc21.x86_64

I have installed OpenSUSE on the machine and their team was able to fix the problem with the commands: hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x10 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x10 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x10 These set the MASK, DIR and DATA bits on pin 4 of the GPIO with the FCH Azalia sound card.
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.
