My sound work fine and the gnome volume control work fine. My card use
the module snd-intel8x0.

I map my mute button on my keyboard in the gnome keyboard shortcut to
the mute field.

More FC3 problems: cannot configure which channel to affect with
multimedia keys.

After mapping the multimedia keys with Preferences | Keyboard
Shortcuts the increase volume, decrease volume and mute keys shows the
visual feedback (a speaker with a volume bar) when pressed. It  looks
perfectly OK, the bar is longer when increased, shorter when
decreased, and the mute button toggles it to a zero state.

The volume, however, is not affected at all, always the same. 

My setup is such that the 'Master' channel does not affect the volume;
the 'PCM' and 'Master surround' does, though. Since the built-in
volume command affects the 'Master' channel I presume this is the
problem. The ACME package had a configuration option to determine
which channel should be affected by the multimedia keys.

BTW, testing with gnome-alsamixer I can confirm the mute bug: The
'increase volume', 'decrease volume' buttons affects the Master
volume; looks fine. The 'mute' button just pulls it to zero, and there
it stays even if you push it again :-(

The ACME package worked in RH9, but not in FC2. Havn't been able to
find a compilable RPM of ACME to try in FC3. (there is a compile bug
which is fixed in the gnome sources, but in the RPM:s).

FC2 had the same problem. 

Sw: FC3, updated as of Jan 18.

Fedora Core 3 is now maintained by the Fedora Legacy project for security
updates only. If this problem is a security issue, please reopen and
reassign to the Fedora Legacy product. If it is not a security issue and
hasn't been resolved in the current FC5 updates or in the FC6 test
release, reopen and change the version to match.

Thank you!

Closing per lack of response to previous request for information.
This bug was originally filed against a much earlier version of Fedora
Core, and significant changes have taken place since the last version
for which this bug is confirmed.

Note that FC3 and FC4 are supported by Fedora Legacy for security
fixes only.  Please install a still supported version and retest.  If
it still occurs on FC5 or FC6, please reopen and assign to the correct
version.  Otherwise, if this a security issue, please change the
product to Fedora Legacy.  Thanks, and we are sorry that we did not
get to this bug earlier.
