Windows 10: Sound not working/Can't system restore

Hello,


I have a Dell Inspiron 15 7577 that I bought in Japan. Last summer, I deleted the RealTek Audio Driver that came with it so that I could use the default "High Definition Audio". This worked fine, but when there was a big update in January to Windows 10, I lost all speaker and headphone functionality.

The "High Definition Audio Device" still appears in the Device Manager, but updating the drive does nothing. The volume icon in the Task Manager shows an X and right-clicking on it to open Settings shows no available output or input devices. Opening the troubleshooter and the only devices that are displayed are currently inactive Bluetooth speakers/headphones and "Digital Audio HDMI - High Definition Audio Device". So maybe the "High Definition Audio Device" in the Device Manager is referring to HDMI sound as well and not the computer's soundcard?

I didn't have any luck updating or installing drivers, so I tried a System Restore Restore to Original Settings, but upon reboot, I got a message that an error was encountered while trying to restore- but no details. What should I do?

:)

 

System Restore Not Working

Where you able to successfully restore your system after trying these suggestions ???? Inquiring Minds would like to Know !

 

Good surround sound headset

I know you say you're not that guy, but stepping into the $250+ range really brings a change in build quality that might have you never having to buy another set. Otherwise, getting 6 speakers with decent sound in a headset is hard, and that's what you are asking for, and I have no suggestions, but just a bump up the list. *Stick Out Tongue
