Have you tried restarting the device? These things are just little special purpose computers. Like their big brothers sometimes you just need to clear things out by restarting them.
Depending on your Roku model and Roku version number you'll find the System restart option under Settings > System > Power or if not there, under Settings > System. Or you can just pull the power plug for a few seconds then plug it back in and wait for the Roku to start up again.
(Note that if yours is a Roku TV with "Fast start" enabled, turning it off and back on just puts it into and out of a standby state and does NOT give you a complete restart. Use the methods above instead.)
Thank you for the restart advice. Been without sound for 3 days. Saw this and it works! Easy fix once you knew what to do. To bad Roku wasn’t helpful.
