At the risk of transmitting harmonics as well as the principle audio...

Plus not all sound card responses are 'flat' so the levels, if outside 
the tested range (say 1500 Hz +/- 500 Hz) vary much, it may be too loud 
(overdriving) or soft.

A simple test, into a dummy load, set your audio tone for a lower tone, 
watch the output, repeat with a mid-range tone and a higher pitched 
tone.  If you don't have to readjust the audio drive to the radio (while 
keeping NO ALC), you're fine.  If you do have change levels, use the 
frequency shifting of WSJT-X to stay within the same range.

Sometimes cheap audio, is REALLY cheap audio.
