From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20040922 Description of problem: Several of the sound volume sliders are not available for me. This happens on a freshly installed FC3 system. The function of the soundcard (snd_via82xx) has been verified in firstboot. I installed the xmms-mp3 plugin from freshmeat and can hear mp3 soundtracks but the volume seems to be set to 100%. So I tried to change the volume level using alsamixer and gnome-mixer. The master-volume slider has no effect at all and strange enough I see a PCM field but no slider is associated to it. There are also several other sliders missing (Line-In, Mic, ...). So sound itself seems to work but I can't change the volume settings. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. try to change sound volume settings 2. 3. Additional info:
Additonal note: When I scroll to the right end of gnome-mixer or alsamixer I find 4 sliders all named VIA DXS. The first one of these indeed does control the volume for me, but it is unclear if this is the PCM or master volume.
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you.
Thanks Dave. The system has been upgraded to FC4 in the meantime and now the volume sliders work as expected.
