Additional context
Add any other context about the problem here.

I found out that importlib.metadata was introduced in Python 3.8 and is no longer provisional from 3.10.

I found out, that python in snap environment is to old:

poschi@bart-nb:~$ snap run --shell indicator-sound-switcher
To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

poschi@bart-nb:/home/poschi$ python3 --version
Python 3.6.9

From snapcraft.yaml I can see that the package is based on core18

indicator-sound-switcher/snap/snapcraft.yaml

Line 2 in 01018d2

base: core18

which means Ubuntu 18.04 LTS (Bionic Beaver).

May be it is possible to update core version?

I have the same issue on 22.04.4 with snap package so I decided to remove snap and install indicator-sound-switcher from PPA.

$ snap remove indicator-sound-switcher

$ sudo apt-add-repository ppa:yktooo/ppa
$ sudo apt-get update
$ sudo apt-get install indicator-sound-switcher

It works fine as my Python version is 3.10.12

$ python3 --version
Python 3.10.12

You may consider this as workaround :-)

Yes I'm aware of the problem and looking for a solution. Unfortunately, switching base in a snap is a hassle (mildly put), because the differences between different bases are huge and poorly documented.

Resolved and released in 2.3.10.1.

Thank you! It is working fine now :-)
