Volume Control

Optiplex 755

If you are on an Optiplex 755, do the following:

1. Open the Volume Control Panel
2. Go to Options, Properties, pick Recording, and make sure all of them are on
   1. Select "Rear Input"
   2. Set this volume about 80% on
3. Change "Recording" to "Playback"
   1. Make sure all are on
   2. Set all volumes to 80%

Oscilloscope

If the "stop" button does not seem to work, just close the whole oscilloscope.

Weird Errors

The following have been happening semi-randomly:

• Closing softscope closes MATLAB - just restart MATLAB. This may happen a couple times... If it keeps happening, just use softscope to get your volumes correct, restart MATLAB, then skip to the next part of the lab without reopening softscope.
• Opening softscope gives an error about the GUI - restart the computer you are on.
