Sometimes the audio service hangs which causes audio playback issues. This is especially true if you use multiple audio devices such as docks, different monitors with audio playback, or USB audio DACs. Simply restarting the service by running the two commands below in a command prompt typically resolves the issue, though, sometimes in chrome I have to reload the tab or sometimes the entire browser.
Open command prompt:
Win + r
type "cmd"
hit run
For 90% of people you just need audiosrv but you can run the optional commands (without the "(optional)"):
net stop audiosrv
net stop AudioEndpointBuilder (optional)
net start audiosrv
net start AudioEndpointBuilder (optional)
This is essentially what fixes the issue when you do the reboot because the audio service restarts during the reboot.
