System: Windows 10 Pro 64-bit (latest version 1803)
Speakers: Bose (older MediaMate)
Earphones: Sennheiser BTD 800 USB
Using the audio manager from Windows 10, set the earphones to be the default device and all audio is okay (i.e. CDs, videos, MLB broadcasts, etc.).
When enable and set the speakers to be the default, NO SOUND – but when choose Test get 'test beep' from left then right speaker.
Suspect there is another setting which I've missed (used to work correctly when had Windows 7).
