Description petrosyan 2007-10-22 02:25:08 EDT
Description of problem:
On a Thinkpad X61 machine "volume up/down" keys change microphone's volume
instead of changing master volume. "mute" key does not work at all.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. boot from rawhide-20071019-x86_64 live CD on a ThinkPad X61 machine.

If you go into System->Preferences->Hardware->Sound what is selected for default
mixer tracks at the bottom of the capplet?

I have realized that the same bug exists in Ubuntu 7.10

The problem is that if you go into System->Preferences->Hardware->Sound nothing
is selected for the default mixer track and somehow the multimedia keys get
bound to microphone level by default. Choosing "PCM" track from the list fixes
the bug. However it should work by default as expected. So I am leaving this bug
open and hope it gets fixed before Fedora 8 release.

This problem is still present in Fedora 8. This is how "Sound Preferences"
window looks like right after install. As you can see none of the channels are
selected. By default the volume keys for some reason change microphone's
Comment 5 Bastien Nocera 2007-11-15 05:58:20 EST
I guess it means this doesn't work as it should on your system:
		/* If no track stored in GConf is avaiable try to use master track */
		if (self->_priv->mixer_tracks == NULL)
			for (m = gst_mixer_list_tracks (self->_priv->mixer); m != NULL; m = m->next)
				GstMixerTrack *track = GST_MIXER_TRACK (m->data);

					self->_priv->mixer_tracks = g_list_append (self->_priv->mixer_tracks,
g_object_ref (track));

The problem is NOT with control-center but with gstreamer. I have a fix on the
Ubuntu bugzilla.

Comment 7 Ray Strode [halfline] 2008-01-02 10:35:15 EST
Thanks for the insight.
Comment 8 Jerone Young 2008-01-05 18:29:38 EST
I have placed a bugzilla in the gstreamer bugzilla:

Comment 9 Bastien Nocera 2008-01-07 05:22:44 EST
I'll wait on feedback from upstream for that one. The patch seems to be more
intrusive than it needs to be, or a work-around.

Did you restart your session, or at least kill gnome-settings-daemon? The patch
added is the same reported as working by Jerone.
Comment 13 petrosyan 2008-01-07 12:30:50 EST
I upgraded to gstreamer-plugins-base-0.10.15-2.fc8 then rebooted the computer,
then created a new user. Logged in under the new user and volume keys were bound
to the microphone volume.
Comment 14 Bastien Nocera 2008-01-07 13:02:10 EST
I put the wrong patch in ;)
But I'm leaving it in as it fixes some issues with gnome-volume-control (and
it's my patch).
