diskOS Disco! 2.7.0

Your music, to go. Disc Shelf joins the firmware, with Navidrome and SMB3 downloads in the same themed interface.

Bring your collection along

• Disc Shelf is built in; no separate app installation is needed.
• Pick Navidrome for artists/albums/tracks, or SMB3 for a simple folders-and-files browser. Only one source connects at a time.
• Familiar library rows, swipe-to-select, Download-only actions, position dots, the A–Z grid and letter circle work across Disco, Null and Squash.
• Finish partial albums or folders with Missing only. Download again replaces only matching copies owned by Disc Shelf; unrelated files are kept. Completed files survive cancellation.
• A jewel-case CD icon, compact headers, wider rows and scrolling selected names make the app fit the round screen.
• New Navidrome files use Artist/YYYY - Album/NN. Track name.ext, without a routine identifier suffix. Unknown years become 0000; collision suffixes protect existing files. Existing downloads are not renamed, and SMB names stay as on the share.
• Downloads show three lines of description, a smaller percentage with smoothed speed, and a larger MiB counter.

Set up Disc Shelf

Hold. Shuffle. Listen.

Choose Shuffle! under Display > Navigation > Gestures > Menu hold. It starts the full song library using the same shuffle path as Library, takes you to Music and shows a themed “Happy listening!” popup. Existing assignments keep their meanings. The common action picker also offers it for menu double-tap.

SongSphere now has a themed guard screen matching Disc Shelf: browse past it freely and press Open SongSphere when ready. Direct track/album/artist Mood editors remain immediate.

Squash Settings headings now align better with the back arrow, with the arrow slightly further inward.

Less unnecessary work

• During Navidrome/SMB3 copies, Wi-Fi power saving is temporarily disabled if enabled, then its exact previous mode is restored on completion, cancellation or error. Already-disabled power saving is left alone. Unsupported driver commands do not block copying; restoration is best-effort if the radio/driver disappears. No permanent preference is changed.
• No Disc Shelf background sync, discovery or full-library rescan. The backend connects only after opening the app and waits when idle.
• Navidrome batches small writes in a temporary 128 KiB buffer, reducing write calls by about 75% in a localhost test. An actual transfer-speed or battery improvement on the Disc has not been measured. Resource checks, cancellation, byte/media validation and final file synchronization remain.
• Guard screens are static: browsing them opens no app database, worker or animation engine.

Privacy and compatibility

Fresh profiles keep passwords for the app session only. Remember password On saves readable credentials in a private file, not encrypted storage. Existing Navidrome configs remain compatible. Navidrome now uses salted tokens, which are still reusable credentials; use HTTPS and keep authenticated URLs private.

SMB3 requires encrypted transport and does not fall back to SMB1/2. SMB3 remains experimental. Encrypted host wire tests passed, but independent physical NAS/Disc compatibility, peak memory/current draw and hot-card removal remain unverified. Navidrome has been used successfully on the owner’s Disc. These results do not guarantee every server or card will work.

The normal firmware install/update paths are unchanged. The 1.0.4 standalone Disc Shelf archive remains a legacy download for older firmware and is not needed on 2.7.0. No Bluetooth, power-button or upstream-settings migration changes were added relative to public 2.6.2.

Updating

Use the normal update guide and existing trusted signing keys. For a first install, follow installation instructions, starting from stock FiiO V2.57.

As always, this is an independent hobby project, experimental and provided as-is. Back up important data before installing.
