Program freezes when playing any move on 1.17.1

[nobu1308]

I'm experiencing a bug that appears to be the same as issues #752 and #768, but I'm encountering it on version 1.17.1.

The root cause may be related to either Kivy (possibly kivy/kivy#9023) or Python.

I found a couple of workarounds:

• pip install kivy==2.3.0 with git cloned Katrain
• Making the play_sound() function in katrain/gui/sound.py blank

KaTrain version: v1.17.1
Installation method: pipx install katrain
Python version: 3.12.3
OS: Ubuntu 24.04

Thanks!

It's also the same as #691

Edit:
Okay after some more testing it seems kivy's bundled sdl2 libraries are also fixed on my distros python-kivy:2.3.1-1, so i just opted to using my system packages with below.

Steps:

sudo pacman -S python-kivy sdl2_ttf sdl2_image sdl2_mixer gstreamer

# venv
python3 -m venv --system-site-packages ~/katrain-env
source ~/katrain-env/bin/activate
pip install -U katrain
katrain

Installing with venv doesnt add the app to the path though, so i just made a tiny bash script and a desktop file for launching said script.

Katrain 1.17.1
Install methond: venv/pip
Python: 3.13.5
OS: Manjaro Linux, KDE Plasma 6.4.1 (Wayland)

@ojsl1 's workaround unfortunately didn't work for me on Arch Linux, but I found a much easier one than patching out the play_sound() function--go to General & Engine settings and uncheck "Sound On". Seems to work fine obviously other than the lack of audio.
