Fix PulseAudio backend not working by updating SoundCard dep

[renyuneyun]

This should fix #107. Though, I'm not sure if this is the best remote version to use.

This is due to a change in Python 3.10.

The key change needed is to use collections.abs.Iteration rather than collections.Iteration.
The way SoundCard fixes this is correct, but it may not be the best. In theory, it may cause backward-compatibility issues for older Python versions. Though the collections.abc module was introduced in version 3.3, which should only cause problems on really old systems.
If really needed, see this SO answer for a better practice.

Considering the repo hasn't had a commit in 2 years, and there are basically no other decent audio visualizer plasmoids (that I can find), I may build and install this PR for my desktop if it works for you xd

As you mentioned "The key change needed is to use collections.abs.Iteration rather than collections.Iteration.", I clone the raw repository rbn42/panon and get submodule as said in README:

git clone https://github.com/rbn42/panon.git
cd panon

# Download SoundCard and hsluv-glsl
git submodule update --init

Then modify ./panon/third_party/SoundCard/soundcard/pulseaudio.py :

...
#The comment part are the lines before modification.
#import collections
import collections.abc
...
#        if isinstance(self.channels, collections.Iterable):
        if isinstance(self.channels, collections.abc.Iterable):
...
#        if isinstance(self.channels, collections.Iterable):
        if isinstance(self.channels, collections.abc.Iterable):
...

Finally build as said in README:

# Build translations (optional)
mkdir build
cd build
cmake ../translations
make install DESTDIR=../plasmoid/contents/locale
cd ..

# To install
kpackagetool5 -t Plasma/Applet --install plasmoid

Done. PulseAudio backend now works for me. Sure there should be a better way to solve the problem, but this is the fastest way.

BTW, my Desktop information:

• OS: Archlinux
• Version of Plasma Framework: 5.106.0
• Python: 3.11.3

Bug is the same as #107

I can confirm that this makes the widget work again on OpenSUSE Tumbleweed

[Oguidan]

what about we create a new repository base of this one and then publish it? If I do will you support me?

[Oguidan]

I have tried, it work also for Ubuntu 23. What do you think about the idea I have given.

[creeloper27]

I have also tried this and it works on Nobara Linux 37 (Fedora 37 Based), would love for this to get merged and a new release to be made so that the plasmoid store version becomes working again as well @rbn42 :D

[creeloper27]

@qspidy You do not need to compile and install from source, if you download the latest version from the plasmoid store and then run sed -i 's/collections.Iterable/collections.abc.Iterable/g' ~/.local/share/plasma/plasmoids/panon/contents/scripts/soundcard/*.py to fix the python files it works as well, I think this is quite a lot faster :P

I have just sent an email to Chen-ZZ which is currently beeing followed by rbn42 and asked him if he is able to contact him, we'll see how this goes, it would be nice if we could keep this project here and with the same name.

update: I have also found rbn42's email and sent one to him as well.
update2: I am starting to contact some of the other maintainers as well, I see some have recent activities on github.

@creeloper27 good idea

Any responses? @creeloper27

Any responses? @creeloper27

It's almost been a year and I got back 0 responses unfortunately :/

Meanwhile someone else forked the project and republished with the name panon-fixed, I guess that can be used instead for now.
