Chronology: My laptop was hit by Lighting because i forgot to unplug a charger, so my laptop is ok but when i restart the laptop, the laptop suddenly doesn't make a sound, and there's a X volume logo in my laptop and the driver selection is Unknown, is IC problem? I you had a same problem as me, can you send an Audio IC for Strix G531 type? (Note: my laptop problem just audio the rest is good and still On)
