> Is there an example or anecdote you have in mind of a platform meddling with mixing? Sure, Android resamples everything to 48kHz, uses software mixing. No workaround. GNU/Linux by default does the same with PipeWire, PulseAudio and ALSA (dmix). One can configure it for bitperfect playback though. I can’t say about modern Windows, the last one I used was Windows 7, and by default it resampled everything to 48kHz too. > USB Audio that is special The last time I saw a non USB audio class device was some 15 years ago. I frankly do not understand, why are you stressing this so much.
