A useless green volume control keeps appearing and disappearing

[vivian-unger]

Ever since I updated my Ubuntu to 16.10, I have seen a mysterious green bar periodically appear and disappear in the upper right corner of my screen. I'm attaching a screen shot of this bar. It looks like a volume control, but I can't do anything with it, such as adjust the volume. If I float my mouse over it, it "greys out" (or really, it becomes a lighter green).

In my efforts to make it go away (because it really is annoying) I uninstalled Pulseaudio. This did indeed make it go away, but I also lost the real volume control on my top panel. I reinstalled Pulseaudio, and neither the real nor the fake volume control came back.

After some internet searches, I found out about indicator-applet. Reinstalling it (sudo apt-get install indicator-applet) put the volume control back in my panel, but it also brought back the ghostly green volume control.

I have therefore concluded that indicator-applet is doing this--why, I don't know. It never did this before the 16.10 upgrade. I would like to discover a way to get it to stop doing this, without actually uninstalling it, since I like having a volume control in my top panel. But I will uninstall it if that's the only way to get rid of the durned thing.

Can anyone help?

Don't think you can easily remove the sound notification witout removing all of them but depending on how serious you are about removing it..

It's a notification? What's it notifying me of? :confused:

EDIT: OK, I read the link. I'm not aware of modifying the volume when it comes up. Maybe there's some hotkey I'm unaware of that I'm pressing?

Thanks for your help, howefield!

I just booted up this morning and the indicator came up while I had my hands completely off the keyboard. It just came up again while I was typing this message. I didn't alter the volume in any way. I think this is a bug.

Is anyone else having this problem?

The only time it's noticeable here is when the volume is changed.

It seems you have a problem or a bug of one kind or another.

If you shut off notifications, does it still happen?

Renaming org.freedesktop.Notifications.service has stopped the volume notification. Though of course it doesn't fix whatever underlying problem is making the volume notification pop up when there's no change in volume.
