Description Matthias Clasen 2007-09-25 14:35:03 UTC
When I use the mixer applet while another volume control (gnome-volume-control
or the pulseaudio volume control) is running, muting happens randomly while I
drag the slider.

Comment 1 Bastien Nocera 2007-09-25 15:17:47 UTC
Problem is that there's no get_mute, so the only way to get the status reliably
is to use the new notification mechanism to get updates.

This is a pretty large change to add to gnome-media right now.

There's also problems with the tracks' left and right channels randomly
unlocking themselves from each other, which are probably due to some get_volume
failing within the alsa mixer plugin.

Which version of the mixer applet are you using? It shouldn't mute the track
when volume is reaching 0 anymore.

Comment 2 Matthias Clasen 2007-09-25 16:19:50 UTC
This is with gnome-media-2.20.0-2.fc8

And, urgh, now that I try again, I see random muting even without any other
volume control app running...

Comment 4 Bastien Nocera 2007-09-25 17:06:54 UTC
So that's the mixer applet running on its own causing problems?

The mute overlay is used for volume == 0, and when muted (properly), so this
means that gstreamer/alsa is sending spurious mute updated messages, or that the
volume getting gets 0.

Could you please ltrace the mixer applet and check the results for failed 

I haven't been able to reproduce the problem. If the problem comes from spurious
mute messages, I'll cook up a patch to gnome-applets for debugging.

Comment 5 Matthias Clasen 2007-10-03 16:06:33 UTC
I cannot really reproduce the problem anymore here. 
So lets assume that things work better now.

Hi there, 

please try also with gnome-media 2.23.3 (should be out in a few hours ;), it
removes the weird code that was muting the device when all sliders where 0, and
was not changing this back according to device events.
