Thanks to
@f205v I've just found this thread, having reported elsewhere (
High-Resolution USB Audio Broken?) that my car with an older firmware version (2020.36.11) had mysteriously lost the ability to play my 24-bit 96- or 192kHz FLAC files.
I reported this to Tesla via the "Report a Bug" feature (probably speaking into a black hole) and then telephoned Tesla service and was amazed to be able to speak with a real human being! She duly took my details and later e-mailed with the usual checks: USB stick formatting, etc. No doubt this will be noted somewhere at the bottom of a very long bug list, then struck off as "low priority" by some manager. Meanwhile, my £2000 "Premium Audio System" is unused because I can't hear my latest recordings and can't bear to dumb them down to 48 kHz (aside: sampling rate IS important: it reveals subtle transients and spatial details that we, as human beings are particularly sensitive to).
Meanwhile, I'm curious as to the legal case here: our cars have lost functionality as a result of a software update. Under English Common Law (which, I believe, underpins much of US law as well) we are entitled to be redress - but no doubt we signed our rights away by agreeing to accept software updates (though in some cases such updates have been forced on individuals as "safety precautions"). Curious.
