The other day my 2 year old son fell on my laptop. The touchpad was pushed in and I received the above message about an audio output device. The touchpad is working fine now but I have no sound on the laptop. I've tried all the methods I could find online. Restoring to a previous date, enabling/disabling sound, etc. The computer acts like there is no option for sound at all. I had Realtek and cannot even find that on the laptop anymore. Likewise when I tried to find sounds in the Device Manager there is not even a sound option. Tried doing a search thru files and programs and the only option for sound that appears is a recorder. Is there anything that can be done to fix this? Any help would be appreciated. Thanks in advance.
