python - Is it possible to ensure audio isn't modified when playing back under Windows -

-

we have python program outputs specific waveforms on audio drive led, easy , cheap robot programming device.

with windows systems we've tested works fine, on systems waveform seems altered. we've used control panel disable 'enhancements' audio output endpoint doesn't seem help.

so, possible, using python, instruct windows play audio unchanged? or of audio gurus here have theory of affecting audio?

sound cards playing audio, not sending data. can't rely on arbitrary signal not being altered hardware, less software. example, many sound cards have capacitor in series output filter out dc bias. if try pass dc-biased (or low frequency) signal through such sound card, distorted. , there's nothing can @ software level.
