Description of problem:
At volume settings below about 15% there is no audio output, once the volume is set to higher than 15% the audio output starts working, but it is a sudden jump in volume (ie the output is not very quiet).
Basically it appears to be impossible to set the output volume to low levels.
It seems that if the volume is set to just above the point where the output disappears quiet periods in the audio will lead to the output disappearing again, at which point it won't re-appear until the volume setting is increased.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Start audio playing (eg Amarok, or Flash videos)
2. Set the volume in kmixer OR pavucontrol to <15%
No audio output
Low volume audio output

Screencast of "alsamixer -c0" showing incorrect setting of "Master" control
I'm seeing the same issue on a Dell Latitude D620 with Fedora 12. I watched "alsamixer -c0" while adjusting the PulseAudio volume via the GNOME panel applet, and PulseAudio seems to be incorrectly setting the "Master" control to zero when the PulseAudio volume is low. See the attached screencast.
The workaround described in the link below (ignore_dB=1) greatly improves the behaviour of the volume control for me
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13. 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bug reports from releases that are no longer maintained.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 '13'.
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 13'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 13 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 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 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.
