Hi,
In the search box on the taskbar, type audio troubleshooter, select Fix and find problems with playing sound from the results, then select Next. Select the device you want to troubleshoot and then continue through the troubleshooter. It will detect and repair issue automatically.
We could go to Device Manager, right click sound driver to update it. Or we could delete the existing sound driver, then reboot computer to load it again automatically. Also we could go to device manager to download and install sound driver manually.
For more information about sound troubleshooting, please refer to link below:
