Bad audio quality in Moodle Kaltura recordings on iMacs under ambient sound conditions. A running log (closed)

  1. Symptom: See title.
  2. Cause: While speakers of the 3.5 mm headset take over from the iMac speakers, when plugged in, the 3.5 mm headset micro does not disable the webcam micro. The webcam micro remains the recording source for Moodle Kaltura (mac os x.6, safari 6, flash 10).
  3. Possible solutions:
      1. 1st choice: is there a way for the admin to override this permanently?
      2. 2nd choice: is there a way for the end user to override this on a case-by-case basis?
      3. "The Califone 3066AV is compatible with both Windows and Mac audio outputs (but is not compatible with iMacs)." ("The Wow starts now!").. Do we have to tie up our boom and lavalier microphones for this?
      4. Try the flash settings by right clicking in the video window, selecting the microphone icon, then choosing the external (= non-webcam) microphone for input.

      6. Fail. The real culprit is the iMacs line-in audio-in for which you need a preamp to get it to work with analog microphones. Preamps seem to start at $40, but for that I can get a PC webcam (Microphone included).

Student email in Office365/Outlook.com slow on reception desk computers

  1. Problem: Since last week (or so; interestingly, only individual users seem to have been affected at first), we seem to experiencing regular (but not consistent) issues with meeting requests mostly
    1. slowness
    2. browser-specific behavior
      1. internet explorer 9: crashes
      2. chrome: crashes
      3. Firefox: (sometimes just seems to hang, with some coercion can bring up an “unresponsive script” warning dialogue that a script is hanging: image
  2. Workaround:
    1. Best so far: if you see the Firefox warning dialogue, check “do not warn again” and click on “continue”(?)
    2. we will try to look into common browser configuration (like popup blockers).
  3. Root cause: ?
    1. Firefox provides only this help on unresponsive script error;
    2. the slowness could be in the actual script, on the client, in the network, on the server…
  4. Resolution: ?

New supervisor role for senior LRC Assistants

  1. A new LRC Assistant list, sorted by hire date, has been posted on the inside LRC reception desk. Use it to determine who is currently the most senior LRC assistant at the desk. The current most senior LRC assistant serves as supervisor and always wears the green supervisor badge pictured below. When the supervisor leaves, the supervisor passes on the badge to the next senior LRC assistant in line.

  3. Supervisors do not have to perform clerical tasks (meeting requests, equipment handling, etc.) as long as there are enough less senior LRC assistants to handle the client load. Rather, supervisors monitor less experienced LRC assistants operating the reception desk computers, equipment etc. , help train them and avoid mistakes.
