+systemctl --user link ~/Projects/hypr-dotfiles/systemd/user/auto-mute.timer
+systemctl --user link ~/Projects/hypr-dotfiles/systemd/user/auto-unmute.service
+systemctl --user link ~/Projects/hypr-dotfiles/systemd/user/auto-unmute.timer
+systemctl --user enable --now auto-mute.timer auto-unmute.timer
+```
