Just to manage expectations: the iPod was a personal music storage and playback device. That’s what it did. So it evolved rapidly to become a great one.
Tesla never has, and never will, prioritize USB. It’s a nice feature they provided alongside streaming, which has been their focus for entertainment. While a lot of us wish they had just licensed usb music software with all the standard features, they did not... they wrote a rudimentary system with half the standard features.
having used USB as my primary Tesla music source since 2012, and participated in all of the threads about it, I’ve learned to manage my expectations and enjoy what’s there. Life is too short to tilt at windmills.
they can’t “fix” gapless playback or gain leveling. They never had it. They could add it, but don’t hold your breath.
they have largely fixed “resume”. Didn’t use to work at all, and now mostly works. I’m convinced that when it doesn’t, it is issue of timing between usb device and startup of other components. They are going to tell you to change devices. Don’t bother unless it is frequent... you will waste time and money.
album art is broken. It DID work and now doesn’t. We should continue making noise about that. And I’m confident they will fix eventually. It took over a year to fix resume when they broke that a few years ago.
asking for a full featured usb player is tilting at windmills... don’t waste your energy and outrage. Enjoy great flac playback and listen to the music
