No sound into earphones

Audacity version is 3.1.3 On my system all sound comes into earphones. I loaded an audio file for testing. On Windows 10 the microphone setting is ON for all apps. All cables and the input to the computer were checked. I played the file-the audio signal in the play window was active so the audio signal is is being detected by Audacity. I tried all three of the playback source options but I hear no sound in the earphones with any of them. What setting am I missing?
