A. Troubleshooting FAQ
Click on highlighted links for more details about a particular subject.
1. No input from sound device.
Check Windows Recording mixer settings. Mic or Line input should be selected.
Depending on your sound device driver software, it may only be possible to select one input at a time.
2. Everything appears to be working, but readings seem innacurate.
There's a good possibility your sound device is off-frequency due to internal clock error. This is very common and easy to compensate for by running the built-in Calibration.
3. Calibration or decoder is reading double the tone frequency.
This is a sure sign that input and/or output level is too high, causing a 2nd or 3rd harmonic oscillation. Solve this by reducing the input (recording) level, and if needed, the output (playback) level for the Wave device. If using the microphone input, be sure the Boost is OFF and the input level is set very low.
