Notice the audio level on the status bar on the top of my screen.

When opening a windows game through proton on steam, closing the game will soft-crash deej as seen in the video above (the tray icon never disappears when deej stops working and I can still close and refresh the app list from the icon). I can open and close non-proton/wine apps without issue.

I ran a very similar experiment again with deej-release instead of deej-dev so I would get a log file. On this attempt deej stopped working before I got a chance to close the game:

Also, here are the contents of my config.yaml:

slider_mapping:
  0:
    - brave
  1: 
    - vesktop
    - Ferdium
    - Discord
    - WebCord
  2: Spotify
  3: deej.unmapped
  4: master

invert_sliders: false

com_port: /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0
baud_rate: 9600

noise_reduction: low

I was initially unsure of the cause but was hinted to wine/proton being the issue from this thread on the deej discord: https://discord.com/channels/702940502038937667/1224327587493445653

Hi, i notice a very similar bug on Linux.
I have the same soft-crashing behavior. For me it occurs whenever:

• i open Steam or
• i open a non-native Steam game

Closing Steam or a closing a non-native Steam game doesn't trigger the soft-crash for me.
As @joe483 described, everything seems normal in debug, except that deej doesn't recognize any slider changes.

A few infos on my setup:
OS: CachyOs (Arch-based)
DE: KDE Plasma 6
Compositor: Wayland
Sound-Framework: Pipewire (with pipewire-pulse)
