Static noise on sanako headsets
2013/11/08
Leave a comment
We seem to have one of these outages in ever class recently. Not sure, whether it is the hardware – the headphone seems not always have static, but frequently. What would be a good way to test this before class, or – to not have to log in individually on all lab computers – at beginning of class?

View a path to where you can start troubleshooting Pearson MyLanguageLab Wimba Voice Java

We used to do proctored LRC chapter exams using this textbook online component, but the Wimba Voice student recording tools stopped working, although a possible solution has been proposed with the problem report. This screencast leads to an exercise where more testing (each supported browser will behave differently – this is Chrome) is possible:: 
Forced downgrade to Color scheme Windows 7 Basic since “exceeded its allowed memory”

This warning and forced downgrade appeared on the teacher after starting using MS-Community Clips (which is just a GUI wrapper for Windows Media Encoder internally, which we used on the same machine successfully while it was still on XP).
-
The error seems slightly more informative than what we received earlier, but I did not manage to investigate since this was in the middle of supporting a teaching use .
Audacity on startup automatically selects the "microphone" as recording device…

- Which is a problem if we do not use the front microphone jack, but rather the rear input:
- Seems to be still an issue on the Group computers….
- Solution is the same as found and documented for the listening stations in relation to problems students had with how Saba Centra handles audio hardware, disable the front jack in mmsys.cpl of Windows7:
Troubleshooting NanoGong recorder assignments for students and rich HTML editor content creation by teachers
2013/10/17
Leave a comment
- Once, when submitting, I got this error? But other teachers managed to test the NanoGong recording assignment application successfully when working as a “permitted student”? That may be related to using a project site.
- If you try to use NanoGong in a browser not fully supportive of Java, you can get easily stuck:
- Firefox which has not been explicitly configured to allow JAVA applets – you will get stuck w/o the option to bypass warning dialogues.
- Chrome is not very forgiving either (here for the HTML editor plug-in):
, but you can get past it: 
. - I am running into more problems using the rich HTML editor recorder plug-in which I supposed to make it easier for the teacher to provide their own audio to their students:
- IE8 does not display the content at all.
- Chrome 30 spits out raw code, and when you locate and click on the loudspeaker icon, I only get this :
. - IE8, on the other hand, draws a blank:
JAVA warning dialogues to bypass during NanoGong activities
2013/10/17

- You may be prompted to update JAVA – likely a not a bad idea:
![java outdated warning_thumb[1]](https://thomasplagwitz.com/wp-content/uploads/2013/10/java-outdated-warning_thumb1_thumb1.png?w=560&h=354 "java outdated warning_thumb[1]")
- Click “RUN”:
![image_thumb[8]_thumb[1]](https://thomasplagwitz.com/wp-content/uploads/2013/10/image_thumb8_thumb1_thumb1.png?w=461&h=542 "image_thumb[8]_thumb[1]")
- Check (1) “Accept”and Click (2) “Run”:
- Click “Don’t Block”:
![CAM03106_thumb[1]](https://thomasplagwitz.com/wp-content/uploads/2013/10/cam03106_thumb1_thumb1.jpg?w=556&h=294 "CAM03106_thumb[1]")
- Even more annoying when warning dialogues do not come to the foreground, and your computer/web browser simply seems to be stuck. Check your task bar/dock for blinking/jumping JAVA notifications, like here:
. - You have to bypass these dialogues only once – per session (lab) or possibly per computer. Choose the right answer, for university assignments, it is safe to “Allow! Allow! Allow! (“run”, “don’t block:”, update”, what ever – use common sense).
- Remember, thinks could be worse, – like if you try to use NanoGong in a Firefox that has not been explicitly configured to allow JAVA applets – read more on our troubleshooting NanoGong page.

Teacher cannot remote control student computers in Sanako Study 1200 Autoscan
2013/10/15
Leave a comment
- Problem:
- The 1st video shows me unable to remote control a student PC from the Sanako Tutor/ Screensharing / Autoscan window, despite (audibly) clicking the mouse and typing on the keyboard.
- The 2nd video demonstrates another strange behavior: Not only can I not remote control the student PC – the Autoscan window keeps showing the same screen even after switching to the next student – although students all work on different texts, as is further evidenced by the thumbnail view of the whole classroom on the left.
- This photo was supposed to demonstrate another oddity: the teacher’s typing (instead of going to the student) flashing up in the upper left of the Autoscan window, between the “Monitor” button and the “Word” window frame – but I missed the right moment. Besides, it may be an additional complication due to the Office 2010 Japanese IME chosen here on both teacher and student. Or it may be the root of the problems (but including mouse? screen not updating)
- Additional Info: For what it is worth: here are the Sanako log files from
- Debugging:
- Can this be replicated with an IME other than Office 2010 Japanese (or any non-Western IM), on teacher and/or student? An actual student should be logged in (<- permissions issue?), preferably many (<- performance issue?). Update: No, could not be replicated yet using another keyboard than an East-Asian IME is involved – bug?

Driverinstaller has stopped working
2013/10/14
Leave a comment
A frequent crash message on both student and teacher station:
Update: I think this could be a Sanako issue. The release notes for Sanako Study 1200 ver 7.1 mention: “Fixed issue where a "DriverInstaller has stopped working" notification was shown in Windows 7 64bit environments when Student application was started up after crashing ”. This indeed looks like the context I have been seeing this in regularly:
