在用户设置，配置，前端通知中，当我选择播放声音为10秒时，它实际的持续时间为消息超时时间，默认60秒，我手动修改了超时时间（在/usr/share/zabbix/include/sounds.inc.php此处修改）为10秒，它的实际播放时间为10秒，当前的设置没有按预期执行，存在BUG。

In the user settings, configuration, and frontend notifications, when I select the sound playback duration as 10 seconds, the actual duration corresponds to the message timeout, which is 60 seconds by default. I manually modified the timeout duration (in /usr/share/zabbix/include/sounds.inc.php) to 10 seconds, and the actual playback duration then became 10 seconds. The current settings are not working as expected, indicating a BUG.
