Check your default audio device in Windows.   Sometimes when DAX is installed, it can change it.  Make sure it is set to the correct output physical device and not a DAX channel.   Also check your default MIC.   Hover your arrow over REMOTE to see what your OS is set to.  Right click on the speaker Icon on the task bar to quickly get to the OS preferences regarding those settings.

I had the same thing happen. If you hover over Remote it may provide a reason. In my case the Windows default playback option had changed somehow to a DAX instead of the speakers.

Yep, the DAX install changed the default playback device.  I just didn't hover over the REMOTE button long enough because if you hover there, it tells you that the default playback device is invalid.....  Nice.  Thanks Chris.

Do you have a slice selected with TX also selected?

You shouldn't have to have a slice with TX selected.  The Remote button just sends audio to your default audio device on your computer.  The problem was that the new DAX install removed my default audio device.  Without a default audio device, SmartSDR doesn't allow you to select the REMOTE button.   If I would have just hovered my mouse over the REMOTE button, I would have seen a dialog box pop up that would have told me that there was no default audio device defined.  Geez, who would have thought I'd actually have to read something? hahaha....
