Q1: I changed the configuration file to a new trigger mode. The default trigger mode is still used, instead of the new trigger mode.
A1: Make sure your computer is not set to hide the file extensions. Your file is incorrectly named "read.cfg.txt" instead of "read.cfg". Uncheck "hide extensions for known file types" under "folder options" and rename your config file to "read.cfg"
Q4: How do I adjust the volume of the board?
A7: No, the headphone jack gives an audio signal only to an external amplifier/active speaker/headphone. The volume adjustment relies on the connected devices.
