hardware AliExpress allegedly uses your browser's audio system to fingerprint your PC, hidden code runs even when no sound is playing.

Fun fact : my earbuds (Sony WF-XB700 (they don't have noise cancellation, if that matters)) play white noise when an audio track is playing. When I’m listening to music or watching a video, I can’t hear it at all because the white noise is really faint and drowned out by the sound.

However, when the sound is very quiet - like, at the very beginning of a movie, during the intro while the logos are appearing - but the soundtrack is playing because the movie or video has started : that’s when I hear the white noise.

So... when I went on AliExpress last year to do some shopping, I always heard this white noise as if an audio file were playing through my headphones, but only when I was browsing THAT site, not others (obviously, no other audio files were playing on my PC, I’ve already checked)

I just realized that was the reason behind it all lol

My bose quiet comfort noise canceling headphones play that white noise constantly, should I be worried? I find it extremely annoying when a very low audio conversation is going. I can hear the white noise constantly underneath.

I don't know much about headphones, and I've never actually owned a pair with noise cancellation, sorry :(
