Was changing setup, it seemed like a good idea at the time.
The result is that I can't link two outputs, at all! The Pi shows them linked, but they are not. I really want to have the link work again, but I suspect I'll have to reinstall.
How can I get the link to work again? From reading other posts I suspect that I've lost the default output, but I can't find any way to set an output as default.
If I have to reinstall, will "77 Revert to default settings" do that? Or is now the time to send it in to get an updated card?
