The plots show measurable differences in the analog output, well above the background noise. Assuming your measurements were done competently this shows that changing the software in the computer system affects the signal sent to loudspeakers. The spikes are far enough above the noise in the FFT bins that it seems likely that the tests will give consistent results, assuming the test conditions remain stable.
