Requirements

  • Kindle with Bluetooth support
  • Jailbroken with KUAL installed
  • Download either SF (softfloat) or HF (hardfloat) version matching your Kindle firmware

How to Install

Install through Kindle Forge (recommended):

  • Click the download button in Kindle Forge for SOX once installed. It will appear in KUAL automatically.

Manual installation:

  1. Visit the official SOX Media Player thread and download the correct zip for your firmware (SF or HF).
  2. Unzip the file on your computer.
  3. Copy the SOX folder to /mnt/us/extensions/ on your Kindle.
  4. Place your music or audiobooks in /mnt/us/music/ on your Kindle.
  5. Safely eject and disconnect your Kindle.

How to Use

  1. Pair your Bluetooth audio device with your Kindle via Settings.
  2. Open KUAL on your Kindle.
  3. Launch SOX Media Player from the KUAL menu.
  4. For internet radio, edit menu.json to add custom streams (see the README and forum thread for setup details).

Notes & Troubleshooting

  • All files in a single playlist or call must share the same format, rate, channels, and bit depth.
  • Bluetooth may sometimes disconnect; if playback freezes, reconnect your device or restart the Kindle.
  • AAC files are not supported — playback attempts will fail.
  • Ensure your device is properly paired before launching SOX for smoother performance.
