I see. Would you be willing to share one of those files here? It would help with debugging this issue.
As for the too slow playback the most likely cause of this would be either the the firmware/Tangara not being fast enough to decode the file in real time or the sample rate reported to the...
Yeah, there is a kind of ALAC files that the firmware can’t currently decode, but as far as I understand those should fail to decode before playback begins — reading the stsd box should...
Without first communicating with the host you can only draw 100 mA, which wouldn’t be enough for Tangara to function properly.
The idf.py monitor command forcefully resets the device (unless you tell it not to do that), which I guess helped here. You are also not the first person, who recently had this type of weird...
