Audio has completely stopped working on HP Spectre x360 today. Looked up how to uninstall and reinstall audio drivers and did that, already did audio check through HP Support Assistant. Have shut down, started up several times. Did not recently update anything before this happened. Worked fine yesterday. Don't know what else to do.

Step 4: You will now get the following confirmation dialog. Select Delete the driver software for this device checkbox and then Yes button when you see the confirmation dialog to go ahead and uninstall the device driver.
Restart your PC once & it should auto-reinstall a working driver.
