Ever since my last firmware update, 2021.4.18, I've been having issues with USB audio. Sometimes it works fine, sometimes it doesn't show up and an error message shows up saying there's an error with the USB port. I've used 3 different USB drives and all of them have this intermittent problem. I've tried flipping which drive is in which port (the 2nd drive is for the dashcam). All my USB drives (including the dash cam one) are 128gb Lexar USB 3.0 drives, "S75" is the model). I listen to audiobooks in the car and it's quite annoying that I can't listen continuously. For example I listen on the way home, everything is fine. I don't remove the USB drive, don't even touch it. The next morning the USB drive is not listed on the audio options and the error message is there. Never had a problem before this last update. Anyone else having this issue?
