Make life simpler in the language lab by disabling extra audio panels
- Problem: Having multiple audio panels enabled can led to too many options = sources of errors and confusion.
- Software (e.g. Saba Centra) may defaults to different audio panels (front “Microphone” preferred over a “Rear Input” that can be used as a Microphone and is the preferred device in your lab (for security, safety and ergonomic reasons).
- Students may make erroneous assumptions and try to reconfigure the PC audio by plugging cables into a different outlet.
- ESP Panel software detects plugging in of devices and asks users to identify whether microphone or line-in device has been plugged into rear input which confuses our users even more.
- Software configuration: On Dell Optiplex 760 under Windows 7 , you can
- run mmsys.cpl,
- go to tab:“recording” devices
- to disable the front panel input microphone:
- select “microphone”(that is the front input)
- right-click and choose “disable”:
- result:
- right-=click and uncheck “show disabled devices”
- to configure the “rear input”:
- select and click “properties”
- go to tab “custom” (may require having an add-on driver installed, consult the DELL driver update utility)
- check “use as microphone”
- check (optional, recommended): “microphone boost”
- select and click “properties”
- “Ok” out of all mmsys.cpl dialogues and (for good measure) restart computer.
- Test your software configuration to work (listening, recording) with the applications used in your lab:
- Sanako student recorder
- Saba Centra
- Audacity
- Voicethread
- Moodle: Audio and Kaltura (even though no webcam)
- Etc.?
- Hardware configuration
- Plug your headset microphone and speaker into the rear audio panel. Tie the microphone cable down with a cable tie. Students have managed to pull the cable through the cable tie, so tie the cable into a knot around the cable tie to prevent that
- Tape (plastic that student cannot push a plug through easily) over the front audio panel and put a label on top: “Do not use! Get help at desk!”. Instruct your help desk student staff.
