Sound card plays audio files but no sound is heard
Last modified: 2009-07-14 11:29:38 EDT
Description of problem:
My soundcard seams to work but no sound is heard during playback.
I have this soundcard:
$ /sbin/lspci |grep audio
00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] AC'97
Sound Controller (rev a0)
When I do this:
aplay -D hw:0 /usr/share/sounds/startup3.wav
it doesn't show any errors and seams to play but no sound is heard.
I tried also running alsamixer -c 0 and all outputs are around 70-80% of volume.
I also tried playing one video ogg theora from redhatmagazine.com and it plays
but I still don't hear any audio from speakers.
I also tried playing with:
pasuspender /usr/bin/aplay -- -D hw:0 /usr/share/sounds/startup3.wav
also I tried killing pulseaudio and starting it again with:

I have the same issue on my inspiron 8200 laptop. After boot into gnome I start
'gnome-volume-control' then I need mute and then un-mute PCM slider then sound
will work. Also shows no errors. Let me know what other info I can provide to
help troubleshoot this.
do you have alsa-utils package installed?
This looks like yet another of those incomplete default mixer initialization
problems. Reassigning to alsa-utils.
It took me a while to see that there are more than one comment here!
anyway, i opened 'gnome-volume-control', and no matter what device and engine
(pulseaudio, alsa, oss etc.) i select, when look in into switches, i can't find
the 'Speaker', so i can't select/unselect it... it's simply not there!
maybe it would help if i said that before this fedora on my laptop, i tried
ubuntu 7.10 and 8.04, as well as fedora 8, and basically had same problem with
any of them...

[root@scooter ~]# rpm -qa alsa-utils
I also noticed that I hear a click sound at the nash kernel boot time. Like it
clicks on and clicks off again a couple of seconds later.
yeah, the same clicking sound from speakers is happening to me too! any ideas?
This is a long time problem, and it is also a duplicate of bug 196597.
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. 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bug reports from releases that are no longer maintained.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 '9'.
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 9'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 9 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:
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
