Description Eddie Lania 2009-10-04 20:49:38 UTC

Description of problem:
In gnome-volume-control when using the output tab's "Fade" slider, front and rear volume levels are reversed ore labeled reversed.
When the slider is moved to rear position, volume of the rear is decreasing and, vice versa, when the slider is moved to front position, volume of the front decreasing.

Also, when te slider is moved maximum to the front position, the volume of the
rear speakers mutes so all volumes are muted (front and rear).

Version-Release number of selected component (if applicable):
I don't know which package provides "gnome-volume-control". Perhaps gnome-media-2.27.90.fix-1.fc11.i586?

How reproducible: with every sound application the results are the same.


Steps to Reproduce:
1. Open "gnome-volume-control" and go to the output tab.
2. move "Fade" slider to front and to rear position.
3.
  
Actual results: front and rear are reversed and when in maximum front position all volumes are muted.


Expected results: Normal Fade.

Nicely spotted on the labels, I fixed that upstream now.

As for the muting, I can't reproduce the problem with the latest git master of gnome-media, so I'll have to update it in F-11. Can you test with 2.27.91?

Package is at:

Comment 2 Eddie Lania 2009-10-05 17:05:40 UTC

Sorry Bastien, but after applying the packages:

[root@p3000fedora ~]# rpm -q gnome-media
gnome-media-2.27.91-1.fc11.i586
[root@p3000fedora ~]# rpm -q gnome-media-libs
gnome-media-libs-2.27.91-1.fc11.i586

The labels are still reversed and sound is still muted.

Regards,

Eddie.

Perhaps it is something that is specific to the EMU10K1 routing? Can you please take a look at bug: https://bugzilla.redhat.com/show_bug.cgi?id=478604
?

Eddie.

This build has been submitted to the updates-testing repo:
http://koji.fedoraproject.org/koji/buildinfo?buildID=135448

Please try it out, should fix both the muting and the reversed labels.

Comment 5 Eddie Lania 2009-10-07 15:55:29 UTC

Hello Bastien,

Thank you for the quick update.

I've installed the new packages. The labels are now correct, nice work.

However, I regret that I have to report to you that the sound still mutes completely when the fade slider is moved to the rear position all the way.

But I've tried it with PulsAaudio Volume control and when I open PAV, go to the "Output Devices" tab and untick the "lock channels together" option and slide the front volume sliders back to zero, the sound is muted also. It is exactly the same.

It feels to me that this could be related to pulseaudio but I would like to hear your opinion about that.

Kind regards,

Eddie.

Comment 6 Bastien Nocera 2009-10-07 16:08:37 UTC

Did you restart your session? Does it work after restarting the session?

Which version of gnome-settings-daemon are you using?

Also check whether disabling all (or one) of the running volume front-ends
works:
- killall gnome-volume-control-applet
- disable /apps/gnome_settings_daemon/plugins/media-keys/active in GConf to
disable the volume keys

And try using pavucontol then.

Comment 7 Eddie Lania 2009-10-07 16:23:54 UTC

Hello Bastien,

I restarted the computer and did all that you suggested but it doesn't help.

I am using gnome-settings-daemon-2.26.1-11.fc11.i586.

Regards,

Eddie.

Comment 8 Bastien Nocera 2009-10-07 17:35:27 UTC

Could you please try to be a bit more methodic in your approach?

What did you disable? Is it still disabled?

Did you try changing the rear/front volume using pavucontrol? Did it mute the whole output when you changed it?

Comment 9 Eddie Lania 2009-10-07 17:52:32 UTC

Ok, here R the steps I followed:


1. restarted pc and logged back in.

2. did a killall gnome-volume-control-applet

3. started gconf editor and disabled /apps/gnome_settings_daemon/plugins/media-keys/active

4. started pavucontrol from the menu and moved sliders for font left and right to minimum

result: rear and front speakers muted.

5. via menu to system -> preferences -> sound

6. tried the fade slider moving to front and rear positions: exactly the same behavior.

Thats it.

Comment 10 Eddie Lania 2009-10-12 15:54:33 UTC

I am having the same problems when I use the pulseaudio master volume control to control volume for an individual application.

I can clearly see and hear that the volume levels of the front and rear (surround) speakers are not equally changed. Only the master level is changed.

But only until the volume slider is moved to the minimum completely, then both front and rear volumes are muted.

So, I think this actually is a duplicate of bug #478604
