The name is based on 'foo' from foobar and the chinese 音 (yīn), meaning 'sound'. It's also a play on 福音 (fúyīn), meaning 'good news'.
As fooyin is built using Qt6, it will follow the system Qt style. If you're using a non-Qt DE such as GNOME or Cinnamon, you will need to install something like qt6ct.
The Flatpak sandbox restricts filesystem access, so fooyin cannot freely read directories outside of its allowed scope. To resolve this, you must grant fooyin access to your music directories and any required paths using a tool such as Flatseal.
The Flatpak uses the desktop notification portal by default, which does not support custom timeouts or album art.
To enable these options, use
Flatseal
to add org.freedesktop.Notifications to fooyin's Session Bus “talk” permissions.
