That's indeed relatively reasonable, but,AFAIK, the audio adapter isn't sold separately. OTOH, you can buy a cheap usb audio dongle for as little as $5.

One example is
this model.
However, this model and other similar models are unpowered and since the USB ports of eInk Kindles don't support
USB OTG, an external 5V power source would most likely be needed.
And since Kindles are Linux machines, this would most likely also involve fiddling with configuration files to load the USB audio driver or Kernel module, which could only be done with jail-broken Kindles.
That's why I posted my question in this forum.
