Hi Ed.
Let's see if I can help again.
With SDR2 software running open MB1 'UTILITY'.
Under menu 'MAIN' there are three boxes.
Sound out SDR.
Sound out PC.
Speaker.
All boxes should be checked.
If that dose not work the MB1 Utility has corrupted. and needs to be reinstalled.
Current Version is V:1.1.2.
That should solve your problem.

It may be a simple matter of MB1 Utility not loading at startup. The symptom of that is that there is no selection as you described.




To correct this, go to Task Manager, Start-Up tab, and ensure that MB1 Utility is Enabled. The Utility must be running before ESDR2 launches.

I had same issue as Ed.
Under MB1 Utility/Main/Embedded audio amplifier all boxes were checked but greyed out in SDR2 Software.
Uninstalled MB1 Utility then reinstalled then everything was fine.
Could be above mentioned issue or as you say MB1 Utility not starting before main software.

Problem correct, thanks for the support, deleted MB1 Utility with my REVO Uninstaller, and reinstalled fresh
install. all is good!
