Re: Unsupported audio signal. Check your device output

4190 is not the latest build available for the 3800 model - build 4200  is.

Check manually at Settings/System/System update/Check now - if it offers 4200, install it and see if this resolves your issue (its being rolled out, so it may not be available for you yet).

Otherwise, what does Settings/Audio/HMDI/Auto detect show as the detected audio modes?

And does this happen in a specific app? or all apps & the menu?
