Today my partner's Windows 10 Lenovo Yoga 720-13IKB decided it no longer wanted to produce any audio. It's coming up with "No Audio Output Device is installed.".
Screenshot of the error message.
The troubleshooter was no help. So I thought okay, I'll uninstall the Realtek High Definition Audio Driver, restart the laptop, and reinstall.
However, the driver now seems permanently gone. I've navigated to the Lenovo site, redownloaded the driver, and attempted to install it. The Realtek Audio Driver Setup Wizard runs with no issues.
Completed Realtek Audio Driver Setup Wizard
But when I launch Realtek Audio, it opens the Device Driver Installation Wizard which seems to show a series of successes and a single failure for the driver.
All the driver names are identical. There's 3 "ready to use rows", 1 "Install Failed" row, and 4 "Not needed" rows. I still haven't managed to get the driver back in the list of drivers in Device Manager and I'm at a loss of what else to try at this point. The laptop has been restarted multiple times. Is there anything I can do to get audio back on this laptop?
My Googling seems to reveal this is a really common challenge but what I've read has boiled down to "if uninstalling and reinstalling the driver doesn't work then the hard drive is busted".
