I have implemented readahead buffering in https://codeberg.org/cool-tech-zone/tang.../pulls/308. This should resolve stuttering for most SD cards. If you have an SD card that stutters with Tangara, I'd appreciate if you could test that pull request for a few hours of playback (stuttering might not show up right away).
After weeks of experimentation and investigation, I have come to the unfortunate conclusion that the combination of some SD cards and the Tangara hardware is just cursed and will never work without stuttering. I wrote a summary of my investigations on the bug tracker. TL;DR: if https://codeberg.org/cool-tech-zone/tang.../pulls/308 doesn't fix stuttering for you, you probably just need a different SD card. It doesn't have to be the most expensive SD card with the fastest advertised speeds because Tangara doesn't come close to those speeds by 5 orders of magnitude. For me the problematic card is a Microcenter brand 512 GB card that I got several years ago. So my advice for buying an SD card for Tangara is just find one at a decent price that isn't some sketchy unbranded too-cheap-to-be-true thing.
