How to fix a crash of the teacher station control panel

  1. Problem: control panel on the teacher station  unresponsive (both hardware and software buttons). No AV and on/off switching.
  2. Cause: Octo switch in the AV cabinet crashed (it needs replacing).
  3. Resolution: Open the door to the AV cabinet and powercycle the switch (= unplug and replug the lower thin black cable in the 1st or top rightmost thin black cable in the 2nd photo). Or use the call button (still functional) and wait for help.

How to quickly check if onboard audio is disabled on student PCs with Sanako headsets

  1. Sanako Study 1200 works best with its own Sanako SLH-07 headsets (they include a USB soundcard). When using these, it is best to completely disable the analog or other sound chip/card that came with your system (onboard). Usually, you can do this in the BIOS.
  2. Before you venture in there, an easy check on which computers is necessary is possible thanks to Audacity displaying the sound card options: Start Audacity form the desktop and look in the dropdowns under the top menu which sound devices Audacity has detected on the system:
    1. This example is form a PC where I had to fix it: 20130702_160932 . Audacity should not see the SoundMax if it has been disabled in the BIOS.
    2. And this is what audacity should see (the USB sound card that comes with the Sanako SLH-07): 20130702_160943

How to fix exception: Sanako Graph Data not installed

  1. Problem: When trying to administer an oral exam, using model imitation, source: file, I could not, but rather I got this error 20130703_141106
  2. Root: The same feature had worked in the morning – however, then the Sanakorecorder interfered with the Sanako tutor. Turned out that the Sanako tutor had been installed over a Sanako Student recorder which caused the tutor pc to connect to itself (distracting, also potentially a liability since it eats up licenses if not managed). In between morning and afternoon exam, the student recorder was uninstalled, but without the required functionality testing afterwards. So this exam had to become the test.
  3. Workaround: Reinstall the student recorder. We used the “test the  Sanako installer” program on my home page to not delay the exam too much. 20130703_142634
  4. Solution: do not install the Sanako tutor over a student installation in the first place.
    1. Either remove the Student recorder after imaging the teacher station with the student image,
    2. or better, image the PC without the added baseline task “Student recorder”.
