Description Frank 2009-07-15 16:40:20 EDT
Description of problem:
Upgraded to Fedora 11 on Dell Latitude C640: no sound. Worked perfectly well before. Everything seems in place, no error messages, all applications work, but no sound. I feel I checked everything... Nothing is muted, all levels are at 100%,  all modules and drivers loaded. I googled and searched bugzilla and a 100 other places, tried all modifications in /etc/modprobe.d/alsa.conf suggested that i could find, reinstalled pulsaudio, and followed all hints that had "no sound in F11" printed on them.
Sorry if I overlooked something, but I searched for days without result...

Comment 1 Frank 2009-07-18 08:12:49 EDT
Well, simple solution is that after opening Preferences->"Advanced volume control" and just *touching* the PCM control (which was already at 100% unmuted), sound reappeared.
I leave this open because it's still a bug, but no longer a serious one.

This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11.  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bug reports from releases that are no longer maintained.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 '11'.

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 11'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 11 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:
