Devices

The Devices panel lets you add, edit, and check Rockbox and mountable players.

What it does

Add Device — Register a new device with name, mount path, model, codec config, and folder layout.
Edit Device — Change any device setting.
Check Device — Compare what is on the device with the library. Shows synced, codec mismatch, to sync, and orphans.
Recheck — Re-read the device after changes (e.g. after a sync or manual file changes).
Set as default — Use this device as the default for sync and Genius.

Mount path — The root path where the device is mounted (e.g. /media/ipod). iPodRocks expects Music, Podcasts, Audiobooks, and Playlists subfolders (configurable).
Codec config — Direct copy (no conversion) or transcode to MP3, AAC, Musepack, Opus, OGG. If you use a shadow library, set the device source to "Shadow" and pick the shadow — no transcoding during sync.
Check Device — Scans the device filesystem and compares with the library. "Codec mismatch" means files use a different codec than the device profile (e.g. MP3 on device, OPUS profile); when you sync with Extra Track Policy set to "Remove", old-codec files are deleted and replaced by the new codec.
Orphans — Files on the device that are not in the library. You can remove them during sync only when Extra Track Policy is set to "Remove"; with "Keep" or "Prompt", orphans are not auto-deleted.

Add a device only when it is mounted. Use the real mount path (e.g. /media/ipod, not a symlink if that causes issues).
Choose codec based on device support. Rockbox supports many formats; use direct copy for FLAC/MP3 if the device plays them. Use MPC or Opus for smaller files.
Use shadow libraries when you want to pre-transcode once and sync quickly to multiple devices.
Check Device before syncing to see what will change. Use "Recheck" after a sync to confirm.
Playback log — Enable if you use Genius playlists; iPodRocks reads playback.log from the device for listening history.
