A while back, the issue was raised of lack of wired audio support on the Kepler Pro. Recently Amazon released a Kindle Audio Adapter for audio-less Kindles, which has spurred people to work out
"How to Make Your Own Kindle Audio Adapter for Under $2", using "a regular micro-USB OTG cable and USB sound card adapter". It occurred to me that it is possible that a similar technique
might work with the Kepler Pro -- a bit clunky perhaps, but an option for those for whom wired audio is a must have.
