Install sound switcher indicator

I’m trying to install the Sound Switcher Indicator application. Downloaded the tar file, extracted it and installed it with the python command:
sudo python3 setup.py install
When i try to start the application nothing shows up in my taskbar. Has anyone used this application and nows what to do to use this app ?

What is this, and why are you installing it using

?

There should be plenty of applets in the repos already, e.g. mate-media for MATE, or something more comprehensive like pavucontrol (not an applet, but…).

Have you tried running it from a terminal to see what output it provides?

I don’t know which DE you are using, but if you are with KDE there is a nice widget you can add to your panel, called “Audio Device Switcher”.
Here how it appears in my panel.

Is this widget also for switching to hdmi audio. Because that is why i want to use this application.

I can’t tell 100%, because I don’t use hdmi audio but it should recognizes all audio sources. Why don’t you try ? It’s easy to grab the widget to your panel and test it. If it does not work you can just remove it. :slightly_smiling_face:

That is the app. I have used this app before without a problem. I did a new install this morning and don’t seem to get it to work. Probably is missing some dependencies.

I got this message when i start it from the terminal:

Traceback (most recent call last):
  File "/usr/lib/python3.8/site-packages/indicator_sound_switcher/indicator.py", line 11, in <module>
    gi.require_version('AyatanaAppIndicator3', '0.1')

    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace AyatanaAppIndicator3 not available

During handling of the above exception, another exception occurred:

You’re right, it’s a missing dependency.
