Thank you so much for this solution! I've been through a number of calls with samsung for them to ultimately not be able to fix the issuea dn telling me it needs new parts. The costs to fix were around $400 through their service company and we were considering just buying a new TV. Resetting the smart hub is NOT a step that samsung had me try at all, they pretty much did everything but reset the smart hub! After resetting smart hub the TV works perfectly again! The volume was sticking, apps were disappearing and losing login info. Thank you!
Same thing has happened to me a few times and is currently doing it now. I thought it was my cable box remote so I switched to TV remote and same thing. It went away on its own before, but now the TV won't even connect with Samsung servers so I can use the Plex app that I wanted to.
I am sorry to hear about this. Please cold boot the television using the following steps.
Turn on the TV.
Press and hold Power on the remote until the television turns off and back on.
Reconnect to your WiFi network.
If you continue to have issues with your audio, please send the serial number for the TV to this PM Link.
