muted output becomes volume == 0 on session restart

Bug #173212 reported by James Westby on 2007-12-01

pulseaudio (Ubuntu)

Bug Description


If I leave the mixer muted (with the mute control, rather than zeroing the volume)
when I logout, when I next log in the volume is set to 0.

I am able to unmute the sound by raising the volume using the slider
or the mouse wheel.

Steps to reproduce:
1. Have audio output at e.g. 50%
2. Mute the output, check that the volume slider is still shown at the same level.
3. Restart the session.
4. Note that the output no longer has the mute checkbox on, but the volume is
at 0%.

I believe this inconsistency is a bug.

I only see it on my snd_emu10k1 system, not on my snd_hda_intel system.

I have seen this problem since gutsy, but the symptoms changed slightly,
presumably with the move to pulseaudio.

I am not sure why you are claiming it is not a bug report, it certainly seems like
a bug to me, could you please explain?

I am setting the status back to new. If you need some more information to
convince you of why it is a bug then please set to incomplete. If you have
a good reason why this behaviour is correct then please set to Invalid again
and accept my apologies.

the bug lack basic informations like the version of ubuntu you are using for one thing. Could you also try if that's specific to the applet or happens when using the mixer for example?

Sorry for the delay, some hardware trouble meant that I couldn't test the bug.

I am using gutsy.

Your question about whether it is specific to the applet has pointed me to some
more information. If I right-click on the applet and open the volume control
the master channel is not muted, but is set to zero volume. The applet
is shows that there is volume, it is just that master is muted.

Also, testing on another system it appears as though the problem is specific
to the driver. I can't replicate the issue on my laptop (snd_hda_intel), and
so it may be specific to snd_emu10k1.

Please let me know if I can provide any more information.

Hi Sebastien,

I still get this, but the symptom has changed slightly, I the "Mute"
option in the context menu is now no longer selected, but selecting
and un-selecting it have no effect.

the issue seems rather a driver or alsa one

Got similar issue with audigy 2zs + nForce 2 400 Ultra. Mute microphone makes its volume 0, not actually mutes it. But when unmuted its volume stays at level 0, but not restores level before mute.

This problem is still present in the latest builds of 9.10 for some people (see

Sorry, looks like we are facing a different problem actually. I apologise for my previous comment, and will file a new bug.
