Hello,
I am using a Kindle Paperwhite 4 (KPW4) and have installed your plugin with the correct settings, but it's not working. When I launch it through KUAL, there's no response. The ;b command can generate a PDF and it shows the MP3 files, but it also fails to play audio.
I understand that your tutorial is for Kindle 5 and Kobo devices, so I just wanted to confirm if there's any possibility of MPlayer running on the KPW4?
Thank you for your help.
