Run mmsys.cpl if you get no audible output in a Blackboard IM call on your PC

Problem: Blackboard IM (4.5.3), in its call window , gives you audio output volume meters , but no actual audio output.
Reason: Blackboard IM seems to have its on in-built idea which device to output audio to, even if you have no actual speakers plugged in to hear, and it is rather difficult to dissuade.
Solution:

Start / Run /”mmsys.cpl”, “OK”: Do the volume meters in there indicate that Blackboard IM outputs to another but your expected speaker (even if the other device is not the default)?
Right-click on the other speaker device and Disable it.
Also make sure to restart Blackboard IM. The built-in startup / dial tones will tell you immediately whether audio output works now

First I create a voice board,
4. and add an audio contribution so that students can respond:
6. Fail:
10. More fail
13. The help offered is of no use: “If the Applet displayed the message “Audio Unavailable”, click here. “ This is neither the error message, nor does the help address Java (but rather audio hardware config) issues
14. But if you refresh (F5 suffices) the window with the Setup Wizard, it starts working?
16. Even the audio recorder:
18. And the voice board (after F5):
What Java version is this under ?
1. really? have I restarted after uninstall of 7.54?
2. The running process here is now Java 6.
4. Still need to test on Java 7.45.
Now a user needs to test from the student view
