Hey there, am interested if someone got custom music playing through BT, or at least has more info that I was able to dig out.
I'm not aware of any Kindle having audio port (besides being able to use VoiceView USB adapter but that's not exactly BT), so I guess this could be used as a list of devices that have BT -

EDIT: Wrong. Some devices have built-in speakers.
Someone had idea just converting the files to an Audible-compatible format and playing those, will try that in a bit -

Playing music in the first place seems to have been made possible in 2011~ but I don't think it applies today, and I bet it doesn't apply to bluetooth -

To play audio files without root, you need to convert into Audible's .aax format. If that'll actually register and play in the Audible app is another thing. I guess nobody anticipated and/or wanted this use case yet, because absolutely no tool seems to be supporting converting TO .aax right now.
There's an open bug issue for ffmpeg to support this

To play audio files with root, someone will have to port an existing music player to the Kindle (or roll their own if they're insane). I'll try looking into this but am far from someone who understands porting to dated Linux systems nor someone who understands audio.
I've tried a bunch of things but I couldn't get any audio to run in any way through SSH.
